KWIVER v1.3.0 Release Notes

This is a minor release of KWIVER that provides both new functionality and fixes over the previous v1.2.0 release.

There has been a batch of updates surrounding serialization. Vital, Arrows, and Sprokit have all received updates to enhance the support of serialization. Vital has new algorithms to support the serialization of different vital types. In Arrows, there are new JSON and protocol buffer serializers for bounding boxes and detected objects. In Sprokit, there are new processes that convert serialized byte strings to Sprokit data ports.

This update also includes a series of organizational changes that reduce conflicts and increase usability.

There are many other changes in this release. These are detailed in the change log below.

Updates since v1.2.0

  • Loadable modules (algorithms and processes) have been moved under
    the .../lib/kwiver subdirectory so that they will not conflict with
    other packages.

  • Replaces sprokit_private_header_group with kwiver equivalent.

  • Remove unused Sprokit CMake support.

Vital

  • Added new class to format config block to a stream and deprecated
    print method in config_block class. Config block formatter provides
    methods to produce different format outputs. Config block
    formatting can be extended with plugins.

  • Added the data_serializer base algorithm to support serialization
    of Vital types for distributed processing and other uses.

Vital Bindings

  • Added python bindings for timestamp class.

Arrows: Core

  • Added support for RPC cameras to the triangulate_landmark implementation.
  • Added a function to render a depth map of a mesh from a perspective camera.

Arrows: FFmpeg

  • Created a new FFmpeg arrow with a video_input algorithm implementation.
    This provides an alternative to the vidl_ffmpeg_video_input in the VXL
    arrow. The goal is to provide direct access to FFMPEG without requiring
    VXL and to improve efficiency, especially with video seeking. Currently
    this implementation is not full featured and does not yet provide a
    complete replacement for the VXL implementation.

Arrows: GDAL

  • Created a new GDAL arrow with an image_io algorithm implementation.
    This allows opening images with GDAL, which is especially useful for
    Geospatial image formats like GeoTIFF and NITF.

Arrows: Serialization

  • Added JSON Serializers for:

    • bounding_box
    • detected_object (partial)
    • detected_object_set (partial)
    • detected_object_type

  • Added Protocol Buffer Serializers for:

    • bounding_box
    • detected_object (partial)
    • detected_object_set (partial)
    • detected_object_type

Sprokit: Processes

  • Added serializer_process and deserializer_process that convert from/to
    serialized byte strings and Sprokit data ports.

  • Added zmq_transport_send_process and zmq_transport_recieve process to support
    Publish/Subscribe distributed processing with ZeroMQ.

Bug Fixes

  • Fixed a problem where ports that were not supplied data in the
    input_adapter_process were incorrectly reported.

  • Fix and issue in the feature_detect_extract_SURF arrow. The arrow was using a dynamicCast
    which causes a segmentation fault on the Mac. On the Mac, symbols exported from an image loaded
    with RTLD_GLOBAL mode are not available to other images unless built with -flat_namespace.

  • Fixed issue with loading logger plugins on Windows due to a semicolon
    that gets appended to environment variables
