= 1.5.0 (2012-02-22) = :: "Better late than never" =

The most notable overall changes are:

new framework for PCL examples in the example/ folder
added the ICCV 2011 tutorial code to the list of bundled applications
a brand new PCL tracking library (libpcl_tracking)
new, well-tested implementations for OrganizedNeighbor and BruteForceSearch in libpcl_search
considerable speedups for: eigendecomposition, covariance matrix estimation, and normal estimation (now running at 30Hz on VGA data)
a lot of bug fixes and code refactorizations and optimizations (thanks to everyone that contributed!)
compilation now defaults to Eigen column major again, but all the code in PCL should compile and work against both row major and column major matrices.
libpcl_range_image is now incorporated into pcl_common, no extra linking required.

`libpcl_common`

added two new methods to compute centroid and covariance at once. Both are faster than calculating first the centroid and afterwards the covariance matrix. The float versions of the new methods are twice as fast but less accurate, whereas the double versions are more accurate and about 35% faster.
fixed a few issues in our ScopeTime class where the creation of the string as well as the cerr were contributing negatively to the time measurements
added empty() to PointCloudEigen::MatrixXf to return whether the matrix is empty or not
added size to PointCloudEigen::MatrixXf and fixed the constructor warnings exposed by -pedantic
added two new Point Types: Axis and ReferenceFrame as they are used in the Reference Frame calculations
added a helper functor (CopyIfFieldExists) for copying out specific data out of a PointT field. See test_common.cpp for usage examples
implemented and tested a fix for feature request #558: Implement IO for PointCloud

`libpcl_filters`

refactored RandomSample to return sorted indices. In addition it now runs nearly twice as fast at it did previously.
fixed and implemented feature #518: VoxelGrid<> performance improvement (roughly 50+ times)

`libpcl_kdtree`

removed unneeded mutices, added asserts instead of constant checks (the user is responsible for passing in valid data!) and sped up a few other things in KDTreeFLANN

`libpcl_search`

adapted use of flann::Matrix to new semantics of the 'stride' parameter, fixing incorrect results and a crash in FlannSearch
changes that affect pcl_features, pcl_search, pcl_octree, pcl_registration, pcl_surface:
- we used to have 3 "overloads" for nearestKSearch and 3 for radiusSearch that every class inheriting from pclk::KdTree or pcl::search::Search needed to implement. Because most of the children always had the same implementation (copy&paste) we moved it up in the base class, made the methods virtual, and only children that need to change that behavior will overwrite it.
- the max_nn parameter from radiusSearch has been changed from int with a default value of -1 to an unsigned int with a default value of 0. Each radiusSearch implementation should check for 0 or >= max_points_in_cloud and branch accordingly (if needed).
- const correctness is now implemented everywhere in all nearestKSearch and radiusSearch operations
added an implementation of KdTreeFLANN for PointCloudEigen::MatrixXf data structures
FlannSearch: don't include flann/matrix.h, move all FLANN includes to impl/flann_search.hpp. Also adapt max_nn parameter in radius search to change r3962 (pass 0 to search for all neighbors instead of -1)
completely new and shiny BruteForceSearch and OrganizedNeighbor classes

`libpcl_octree`

fixed issue #513 (bug in octree iterator)
fixed octree bounding box adaption
fixed range test in getPointByIndex method (octree)
fixed bug #604 & removed compiler warnings in Visual Studio 10

improved performance with std::deque in OctreeBreadthFirstIterator class
added breadth-first octree iterator and depth-first octree iterator classes, restructured octree iterator classes, moved "getVoxelBounds" method from OctreeIterator class to OctreePointCloud class

`libpcl_sample_consensus`

added explicit checks + errors for NaN covariance matrices
fixed a crash on 32bit platforms (thanks bharath)
fix for #498: Bug in setOptimizeCoefficients for pcl::SACMODEL_SPHERE. The issue actually exposed a grave bug introduced with r2755, when we switched from CMinPack to Eigen. The fix touches all segmentation models in pcl_sample_consensus using Levenberg-Marquardt, and TransformationEstimationLM in libpcl_registration. Also added unit test to catch this in the future.

`libpcl_io`

fix row-major/column-major issues in I/O (#578 related)
fixed #593 by removing unimplemented method declarations
added a saveVTKFile method helper for saving sensor_msgs::PointCloud2 data
added support for reading PCD ascii and binary files (binary_compressed not implemented yet!) for pcl::PointCloudEigen::MatrixXf datatypes.
implemented and tested a fix for feature request #558: Implement IO for PointCloud
added PointXYZRGBA callbacks for OpenNIGrabber and PCLVisualizer
fixed issue #565
fixed a few bugs in PCDReader regarding uint8/int8 data values and added a comprehensive unit test for all possible combinations of data types that we support in PCL
added isValueFinite for checking whether a value T is finite or not, and rewrote the PCDReader bits of code that perform the is_dense checks
integrated libply written by Ares Lagae as an independent component in io
rely on ply library for PLY parsing, remove the old parser and use the freshly integrated libply, change the namespace ::ply to ::pcl::io::ply to avoid any potential issue

`libpcl_surface`

Updated convex hull. It should now be somewhat faster, and allows users to optionally specify if the input is 2D or 3D, so the input dimension need not be calculated every time.
fix for #562: pcl::ConcaveHull crashes on an empty cloud (thanks Mourad!)
added option to ensure that triangle vertices are ordered in the positive direction around the normals in GreedyProjectionTriangulation
fixed issue #489 in GreedyProjectionTriangulation
fixed triangle vertex ordering issues in OrganizedFastMesh
MarchingCubes now adheres to the new pcl_surface base class architecture
added PCLSurfaceBase base class for MeshConstruction and SurfaceReconstruction, to unify the API around setSearchMethod(&Search) and reconstruct(&PolygonMesh)
added marching_cubes_reconstruction tool

`libpcl_features`

fixed issue #550: Uninformative error in VFHEstimation (thanks David!)
fix for #504: Make ShapeContext and SpinImage uniform (thanks David!). Note: this is an API breaking change, as setInputCloudWithNormals, which was deviating from the FeatureEstimation API is now replaced with patched setInputCloud and setInputNormals, thus no longer causing an error. However, we are confident with this change as the API was broken, so this is a bug fix.
fixed a bug in the PointCloud<MatrixXf> feature estimation and I/O regarding the fields count property
fixed an issue where the header stamp should only be copied from a PointCloud into a PointCloud in PCL standalone, and not in PCL in ROS
optimized RSD computation

fixed issue #539 (fpfh_estimation tutorial)
fixed issue #544 (overflow in implicit constant conversion warnings)

added getter/setter for maximum number of inner iterations to control number of optimizations in GeneralizedIterativeClosestPoint
fixed issue #507
fixed issue #533 (WarpPointRigid missing EIGEN_MAKE_ALIGNED_OPERATOR_NEW)
fixed issue #464 (already defined function pointers)
fixed a grave bug on 32bit architectures where MapAligned was used incorrectly

`libpcl_segmentation`

fixed a segmentation fault in SACSegmentationFromNormals caused by calling segment without passing the input XYZ or normal data
added a missing setDistanceFromOrigin to SACSegmentationFromNormals for SACMODEL_NORMAL_PARALLEL_PLANE (thanks A. Barral)

`libpcl_visualization`

added PointXYZRGBA callbacks for OpenNIGrabber and PCLVisualizer
fixed two bugs where a segfault would occur in addPolygonMesh when the input cloud would be empty, as well as #563 : PCLVisualizer::addPolygonMesh crash (thanks Mourad!)
added the capability to remove a cloud when removeShape is called, to preserve API backward compatibility (a PolygonMesh is not treated as a CloudActor inside PCLVisualizer)
fix #472: at startup the camera view pointis set to last added point cloud, but with the key combination ALT+r on can iterate through the view points of the visualized point clouds.
added addPointCloud method for sensor_msgs::PointCloud2 data (useful to bypass the conversion to XYZ for pcd_viewer)
added PCL_VISUALIZER_IMMEDIATE_RENDERING for processing large datasets
refactorized pcd_viewer to consume less memory by skipping the intermediate conversion to PointCloud<PointXYZ>, clearing the PointCloud2 data once converted to VTK, and enabling intermediate mode
added setPosition to pcl::visualization::ImageViewer for allowing the image viewer to be moved somewhere else on screen
changed the openni_image viewer tool to display both RGB and depth images
fixed a nasty bug where the scalars range were not correctly updated in the mapper on updatePointCloud thus causing weird VTK warnings at the console
added setupInteractor to allow QVTK customizations
pcd_grabber_viewer now shows the recorded images in PointXYZRGB clouds, and can use fps=0 and trigger each new frame manually by pressing SPACE
fixed an BGR/RGB issue in image_viewer
added setKeyboardModifier to change the default keyboard modifier from Alt to Shift or Ctrl so that in QVTK or other widgets, we can still use shortcuts like Mod+r, Mod+f, etc
PCLVisualizer is now working with VTK compiled for cocoa, no X11 necessary on OS X
build bundle executable for pcd_viewer if VTK is compiled with Cocoa. With that the keyboard events are handled by the application
modified openni_passthrough to use QVTK instead of VTK
added PCLVisualizer zoom in/out via /- [ alt]
implemented feature #516 (pcd_viewer multiview with .vtk files)
added showMonoImage for displaying a monochrome unsigned char 2D image in PCLVisualizer
added setFullScreen and setWindowBorders methods to allow an user to change the full screen/border properties of the PCLVisualizer GUI
fix for issue #519 (set the minimum number of cloud points to 1 in vtkLODActor)
fix for issue #524 (ctrl problem with pcd_viewer)
fix for issue #532 (PCLVizualizer::addCoordinateSystem() switch from Eigen::Matrix4f to Eigen::Affine3f)

fixed issue #525 (pcd_viewer did not handle nan values correctly in fields other than x, y, z)
fixed a bug where changing the point color using setPointCloudRenderingProperties would not update the actor's colors on screen
workaround for displaying FPS rate on PCLVisualizer - disabled backface culling because of known VTK issue

The most notable overall changes are:

changed the default on the order of data in all Eigen matrices to be row major -DEIGEN_DEFAULT_TO_ROW_MAJOR (Eigen defaults to column major). Be careful if your code was using 1D index operators, as they might be broken! See http://eigen.tuxfamily.org/dox/TopicStorageOrders.html and http://listengine.tuxfamily.org/lists.tuxfamily.org/eigen/2011/12/msg00062.html.

`libpcl_common`

added an isFinite method to check for x/y/z = NaN in point_types.hpp
moved internal headers from pcl/ros/point_traits.h into pcl/point_traits.h and pcl/ros/for_each_type.h to pcl/for_each_type.h (these headers are for internal use only and should have never been imported by user code - however pcl_ros in perception_pcl_unstable will need to be modified when following trunk after this revision, as that is the only external piece of code that should import these headers)
fixed one of the constructors for pcl::PointCloud<T> (cloud, indices) that was incomplete
no longer checking "frame_id" parameters in header for operator += in pcl::PointCloud<T>
added operator + for pcl::PointCloud<T>
improved doxygen documentation all around libpcl_common

added CloudProperties class for optional properties for pcl::PointCloud<Eigen::MatrixXf>, and moved sensor_origin_ and sensor_orientation_ there (as properties.sensor_origin and properties.sensor_orientation), and removed header, while keeping header.stamp as properties.acquisition_time
fixed the copy constructor (vector<size_t> -> vector) and added an implementation for the + operator
added a general convolution class. Convolution handles point cloud convolution in rows, columns and horizontal directions. Convolution allows for 3 policies: zero padding (default), borders mirroring and borders duplicating through PointCloudSpring class
refactorized PointCorrespondence and Correspondence into the same thing, per issue #458
added ChannelProperties in preparation for 2.0
fixed bug #445: Overloaded the setIndices method in PCLBase so that it can accept boost::shared_ptr<const std::vector> >
disabled unit test for getMatrixXfMap in DEBUG mode, as it was failing due to eigen's strictness on aligned/unaligned data, and added const+non consts versions

better Doxygen documentation to PassThrough, VoxelGrid and Filter
moved the set/getFilterLimits, set/getFilterFieldName, and get/setFilterLimitsNegative from Filter into VoxelGrid and PassThrough, as they were the only filters using it. The rest were not, thus leading to user confusion and a bloated API.

`libpcl_kdtree`

fixed bug #442: reversed template parameters preventing use of nearestKSearchT and radiusSearchT in pcl::search::Search and pcl::kdtree:KdTree

`libpcl_search`

cleaning up OrganizedNearestNeighbor as well as implementing one of the missing radiusSearch methods
improved documentation for libpcl_search and silenced all Doxygen warnings
removed auto (it needs to be completely rewritten and was left in a very bad state)
made sure all the output of the search method is consistently returning 0 in case the nearest neighbor search failed and not -1
updated kdtree wrapper code for the latest FLANN release

fix: rgb values need to be packed before saving them in PointCloud2 for PLYWriter
added example code for accessing synchronized image x depth data
added support for the Stanford range_grid element and obj_info for PLY files. If you chosse to use range_grid instead of camera then only valid vertices will be written down to the PLY file.

`lipcl_keypoints`

added refine method for Harris3D corner detector
rewrote big parts of the NARF keypoint extraction. Hopfully fixing some stability issues. Unfortunately still pretty slow for high resolution point clouds.

reviewed and slightly modified mls implementation. Added MovingLeastSquaresOMP OpenMP implementation
new architecture for the mesh processing algorithms using VTK: MeshProcessing
overloaded reconstruction and performReconstruction in SurfaceReconstruction to output a PointCloud<T> and vector<Vertices> as well
added a new class called MeshConstruction per API design decision to split the surface reconstruction methods into topology preserving (EarClipping, OrganizedFastMesh, GreedyProjectionTriangulation) and the rest. The new class implements a reconstruction/performReconstructionforPolygonMesh(for backwards compatibility purposes) and a faster set of the same methods forvector`
refactorized GreedyProjectionTriangulation by making it inherit from the new MeshConstruction base class, and removed a lot of old buggy code
overloaded performReconstruction (PointCloud<T> &, vector<Vertices> &) per the new SurfaceReconstruction API
fixed a bug in OrganizedFastMesh where the x/y/z indices were assumed to be 0/1/2, and made it part of the MeshConstruction API

fixed ShapeContext3DEstimation computation and unit tests by switching from stdlib.h's random () to Boost.
fixed a bug in IntensityGradient: need to demean also intensity values, otherwise its assumed that the hyperplane goes always through origin which is not true
overloaded compute in pcl::Feature to save the output in an PointCloud<Eigen::MatrixXf>. Added partial specialization on Eigen::MatrixXf to all features and implemented computeFeature (PointCloud<MatrixXf> &output)
major doxygenization work

added new unit tests for the Eigen::MatrixXf output
fixing the MacOS GCC 4.2.1 compiler segfault by removing the OpenMP #pragma (related to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35364 ?).
fixed bug #468: refactored to make floor explicit.
added a setUseInternalCache method for PFHEstimation to use the internal cache on demand only. Other fixes to PFH/FPFH/PPF signatures (histogram sums were not adding up to 100.0 in some cases)
major improvements for integral images + added template specialization for one dimensional integral images

`libpcl_registration`

fixed some bugs in ELCH, thanks Frits for pointing them out
Big ELCH cleanup.
- elch.h (API changes):
- Use Boost bundled properties for LoopGraph, every vertex stores a pointer to the corresponding point cloud in graph[vertex].cloud.
- loop_graph_ is now stored as a shared_ptr.
- loop_start_ and loop_end_ are saved as ints for now (will change in the future).
- loop_transform_ is not stored as a pointer (may change in the future).
- elch.hpp:
- Remove call to PCLBase::initCompute() as ELCH doesn't use a single input cloud or indices.
- Change loopOptimizerAlgorithm to use start and end of the loop as stored in the object.
- Adapt to API changes in elch.h.
added 2D implementation of Normal Distributions Transform for registration (Biber, Strasser; 2003), including example tool program.
reworked internal Registration API: Remove private computeTransformation without guess, make computeTransformation with guess abstract, Adapt all classes implementing Registration accordingly.
implemented SampleConsensusInitialAlignment with initial guess (thanks Dennis Guse)
cleaned up the CorrespondenceRejector API, per #375
apply Mourad's patch for #454; add more doc comments

added updateFeatureHistogram functionality to PCLHistogramVisualizer, per #456 (thanks Asil!)
added patch from Adam Stambler (Bug #396)
added removePolygonMesh to make the API more user friendly (addPolygonMesh was already existing, but the polygon meshes were removed using removeShape until now)
made the polygon meshes actually implement CloudActor structures internally, so that we can use different colors per vertex
added updatePolygonMesh and improved the efficiency of addPolygonMesh for fast online rendering (i.e., produced via OrganizedFastMesh)

= 1.3 (2011-10-31) = :: "Gaudi" =

From 1.3 we are constructing the Changelist for each library separately, as they can in theory be mixed and matched with older versions (though we officially do not support this yet). The most notable overall changes are:

removed wxWidgets as a dependency from PCL and implemented the Image visualization classes using VTK
removed cminpack as a dependency from PCL and implemented the LM optimization functionality using Eigen
added a new library called PCL Search (libpcl_search) that has a more uniform API for nearest neighbor searches and stripped the unneeded functionality from libpcl_kdtree and libpcl_octree. Search now wraps KdTree and Octree for NN calls. This is a MINOR API BREAKING CHANGE. To change your code switch from:

pcl::KdTree -> pcl::Search (if the purpose is to use one of its children for search)
pcl::KdTreeFLANN -> pcl::search::KdTree
pcl::OrganizedDataIndex -> pcl::search::OrganizedNeighbor

improved MacOS support
improved documentation and unit tests
added lots of application examples and demos. Note: not all have a complete functionality... we will try to clean this up in 1.4 and future releases.

Build system changes

define PCL_ROOT environment variable using the NSIS installer
removing test+python from the dependency graph
fixed bug #374
remove cminpack from PCLConfig.cmake cmake and 3rdparty (switched to Eigen's Levenberg-Marquardt implementation)
update NSIS.template.in : use CPACK_PACKAGE_INSTALL_REGISTRY_KEY as the registry key
added the capability to build an all-in-one installer
fixed the build system to work 100% on Android and MacOS

`libpcl_common`

add overriding for operator[] to shorten code
add a setIndices method that computes indices of points in a region of interest
add demeanPointCloud with indices as PointIndices as well
added eigen allocator to correspondence vectors (pcl::Correspondences) and adapted all registration modules => be sure to use pcl::Correspondences instead of std::vector<pcl::Correspondence>
fixed a few doxygen errors
added simple stop watch for non-scoped function time measurements and made ScodeTime derived from StopWatch
fixed a bug in getRejectedQueryIndices, wrong output when order of correspondences have been changed
moved getRejectedQueryIndices to pcl/common/correspondence.h
added more doxygen documentation to the registration components
marked all getRemainingCorrespondences-functions as DEPRECATED, we sould replace them with purely stateless version outside the class body
fixed a const missing in PolynomialCalculationsT (#388 - thanks Julian!)
add PCL_DEPRECATED macro, closes #354.
added PointXYZHSV type and the conversions for it
added check for endianness for the Android platform

`libpcl_search`

BIG changes introduced - migration from KdTree to pcl::Search: moved OrganizedDataIndex and OrganizedNeighbor classes to libpcl_search
added new templated methods for nearestKSearch and radiusSearch for situations when PointT is different than the one the KdTree object was created with (e.g., KdTree vs nearestKSearch (PointT2 &p...)
added two new methods for getApproximateIndices where given a reference cloud of point type T1 we're trying to find the corresponding indices in a different cloud of point type T2
refactorized a lot of code in search and octree to make it look more consistent with the rest of the API
fixed a bug in octree_search which was semantically doing something bad: for each radiusSearch/nearestKSearch/approxNearestSearch call with a PointCloudConstPtr, the octree was getting recreated. Changed the API to be consistent with the rest of PCL (including pcl_search and pcl_kdtree) where we pass in a PointCloud instead of a PointCloudConstPtr which simply calls searchMethod (cloud.points[i], ...)
minor code optimizations
renamed organized_neighbor.h header in pcl_search (unreleased, therefore API changes OK!) to organized.h
disabled the auto-search tuning as it wasn't really working. must clean this up further
remove all approxNearestSearch methods from the base pcl::Search class as they did not belong there

`libpcl_io`

use stringstream instead of atof because of locale issues in IO (note that we can't use the ifstream directly because we have to check for the nan value)
added locale independent PCD ASCII i/o
implemented setMapSynchronization for pcl::PCDWriter. When set, msync() will be called before munmap() in the pcl::PCDWriter::write* calls, which guarantees data reliability. Though I/O performance is 300% better when unset, data corruption might occur on NFS systems, as indicated by http://www.pcl-developers.org/PCD-IO-consistency-on-NFS-msync-needed-td4885942.html.
added new writeBinaryCompressed functionality for general purpose sensor_msgs::PointCloud2 data (which is still our generic data container in PCL 1.x)
added additional unit tests for binary_compressed
fixed a grave bug in PCDReader (most likely introduced a few releases ago due to code refactorization) where the data was incorrectly copied if a PCD ASCII file had a field with multiple count elements (field.count) as first. Binary files are not affected by this bug. Added an unit test to catch this in the future.
added functionality for openni_grab_frame (added optional command line options, optional output filename, chose output format)
changed to new location of samplesconfig.xml for OpenNI
added signal and slot blocking into grabber. Using blocking to skip first frame in openni_grabber, since it is corrupted
added PLY format file support in binary and ascii mode (requires boost::iostreams library)

`libpcl_keypoints`

added 3D versions of Harris/Noble/Lowe/Tomasi and Curvature-based keypoint detection... scale space still missing
work on making SIFTKeypoint more flexible by saving scale only when the output point type contains "scale" (the catch is that all point types must be correctly declared via our macros - see the modifications in test_keypoints.cpp). This allows us to use a SIFTKeypoint<PointXYZRGB, PointXYZRGB> and thus removes the constraint on using copyPointCloud afterwards.
fixed an issue in SIFTKeypoint where width/height were not correctly set

`libpcl_features`

specialize std::vector for Eigen::Matrix4f (alignment issue with msvc 32bit) in SHOTEstimation
added a faster (eigen-based) integral image calculation => sped up normal estimation to 15Hz
added Unique Shape Context (USC) feature descriptor
added Shape Context 3D feature descriptor
fixed a bug in the normalization factor of VFH for the distance component (only affecting if set distance component is true)
fixed a few bugs regarding Windows build introduced in earlier commits
BIG changes introduced - migration from KdTree to pcl::Search
merged libpcl_range_image_border_extractor into libpcl_features. There's absolutely no reason why we should have 2 libraries generated from the features module.

`libpcl_filters`

added FilterIndices functionality #315
added a RandomSample filter which makes use of indices #323
added a new (very fast) class for data decimation: ApproximateVoxelGrid
fix for #369 (StatisticalOutlierRemoval crash when input dataset is empty)
implemented feature request #346

`libpcl_octree`

added function genVoxelBounds to octree pointcloud class
added octree neighbor search class
added octree-ray-tracing patch to octree_search class
buxfix in octree ray traversal function getIntersectedVoxelCentersRecursive
added unit test for getIntersectedVoxelCentersRecursive
added method getIntersectedVoxelIndices for getting indices of intersected voxels and updated unit test
refactorized a lot of code in search and octree to make it look more consistent with the rest of the API
fixed a bug in octree_search which was semantically doing something bad: for each radiusSearch/nearestKSearch/approxNearestSearch call with a PointCloudConstPtr, the octree was getting recreated. Changed the API to be consistent with the rest of PCL (including pcl_search and pcl_kdtree) where we pass in a PointCloud instead of a PointCloudConstPtr which simply calls searchMethod (cloud.points[i], ...)
minor code optimizations
renamed organized_neighbor.h header in pcl_search (unreleased, therefore API changes OK!) to organized.h
disabled the auto-search tuning as it wasn't really working. must clean this up further
remove all approxNearestSearch methods from the base pcl::Search class as they did not belong there

`libpcl_registration`

fixed a minor bug in CorrespondenceRejectorSampleConsensus: getRemainingCorrespondences tried to nput_ although it should only use the given input correspondences
added missing implementation for TransformationEstimationLM on correspondence vectors
added eigen allocator to correspondence vectors (pcl::Correspondences) and adapted all registration modules --> be sure to use pcl::Correspondences instead of std::vector<pcl::Correspondence>
fixing the API: a few left inconsistencies between vector<Correspondence> and Correspondences. The latter is to be preferred as it contains the Eigen aligned allocator.
added new ELCH loop correction API (New pcl::registration::ELCH class (WIP), add Registration::Ptr typedef)
added unit tests for the (new) registration API and all registration components
Further cleaning up registration code and writing documentation.
- fixed bug in getRejectedQueryIndices, wrong output when order of correspondences have been changed
- moved getRejectedQueryIndices to pcl/common/correspondence.h
- added more doxygen documentation to the registration components
- marked all "getRemainingCorrespondences"-functions as DEPRECATED, we sould replace them with purely stateless version outside the class body
Update: remove ciminpack dependency and rely on eigen for LM
Fixed a bug in ICP-NL by modifying WarpPointRigid to preserve the value of the 4th coordinate when warping; Re-enabled missing unit tests for ICP and ICP-NL
Added point-to-plane ICP
added nr_iterations_ and max_iterations_ to the initializer list (were mising)
Fixed bugs in WarpPointRigid3D and TransformationEstimationLM
fixed a problem where if no correspondences would be found via nearestKSearch, the RANSAC-based rejection scheme would fail (thanks to James for reporting this)
changed the default LM implementation to use L2 instead of L2SQR
Added a new TransformationEstimationPointToPlaneLLS class that uses a Linear Least-Squares approximation to minimize the point-to-plane distance between two point clouds
Added the ability to specify the error function to be minimized in SAC-IA (see Feature #362)

`libpcl_sample_consensus`

reimplemented the Levenberg Marquardt code that was using cminpack with Eigen, thus dropping the cminpack dependency for PCL

`libpcl_surface`

fixed bug in surface/mls: when no search interface and no tree is given, mls creates its' own tree, but didn'tupdate the search method to use
added citation for Rosie's work (http://dl.acm.org/citation.cfm?id=1839808)
added some error checking for missing/ill formed inputs for MarchingCubes
don't delete smart pointers (thanks Chytu: http://www.pcl-users.org/Seg-fault-while-using-VTK-Smoother-tp3380114p3381648.html)
added computation of area and volume for convex hulls.

`libpcl_segmentation`

added a labeled cluster euclidean segmentation method

`libpcl_visualization`

fixed an issue where saveScreenshot was not correctly initialized with the proper renderer, thus not saving the data
supporting fontsize in addText (per feature #365)
fixing the interactor style by ignoring all combinations in OnChar that we cover in OnKeyDown
added removeAllShapes and removeAllPointClouds per #353
renamed deleteText3D to removeText3D to consolidate the API
fixing the API: a few left inconsistencies between vector<Correspondence> and Correspondences. The latter is to be preferred as it contains the Eigen aligned allocator.
added patch from Lucas Walter to fix pcl::visualization::PCLVisualizer::removeAllPointClouds and removeAllShapes
fixed a few doxygen errors
cleaned up the PCLHistogramVisualizer API by moving to a vtk interactor instead of ours, and removed unnecessary calls such as saveScreenShot (never used with the histogram visualizer, and most likely buggy), wasStopped and resetStoppedFlag (never used).
removed PCLVisualizerInteractor and switched back to a better default vktWindowRenderInteractor for VTK >= 5.6. Adjusted and fixed the internal API. No public API changes were made (except the removal of the PCLVisualizerInteractor class which was never meant to be used externally anyway).
cleaned up and implemented the ImageViewer class properly and demonstrated it in a single thread via openni_viewer. The other tool (openni_viewer_simple) will not work due to CloudViewer starting its own thread and thus clashing on the same OpenGL context.
fixed the correct order in initializer list for ImageViewer
removed wxWidgets completely from the codebase
added implementation for markPoint to ImageViewer to mimic older wxWidgets-based code
fixed an issue in PCLVisualizerInteractorStyle where mouse events were not properly mapped in Qt (#389 - thanks Adam!)
added an extra field of view to the camera paramers (#392 - thanks Adam!)
small bugfix when the radius_sphere was different than 1 for renderViewTesselatedSphere

Pre 1.0 (copied from http://pcl.ros.org/ChangeList) - for historical purposes.

The version numbers below belong to the perception_pcl stack in ROS, which coordinated both the release of PCL, as well as the release of the ROS PCL wrappers. From 1.0 onwards PCL got separated from ROS, and the release process of perception_pcl and PCL diverged.

[[flann]]
Updated to version 1.6.8
[[pcl]]
