- Building require ITK version 4.XX and cmake version 2.6 or later
- legacy tool ( volume_patches ) requires LIBMINC ( https://github.com/BIC-MNI/libminc )
These programs were originally designed to be used with MINC files, but should work with any file format supported by ITK version 4 Most tools have an optional paramter called search radius - which specifies how non-local the search should be (in voxels) and patch radius - the radius of the local patch used to extract features.
Denoising requires specifying noise level ($sigma), and optionall search radius $search_radius and patch radius $patch_radius
itk_minc_nonlocal_filter input.mnc output.mnc --noise $sigma --search $search_radius --patch $patch_radius
Adaptative denoising have optional parameters: search radius $search_radius and patch radius $patch_radius
itk_minc_nonlocal_filter input.mnc output.mnc --search $search_radius --patch $patch_radius --anlm
All segmentation tools and scripts require library of labelled samples.
Segmetnation tool require library of presegmented examples $train, number of classes including background $classes and optionally search radius and patch radius
Training examples are referenced in a comma separated file in the format: <image.mnc>,<labels.mnc>
itk_patch_morphology input.mnc output_labels.mnc --discrete $classes --search $search_radius --patch $patch_radius --train $train
Several high level scripts are included in scripts directory:
ventricles_segmentation_pipeline.pl- segmentation script for latera ventricle segmentation, uses volume_patches program from legacy directoryhcag_segmentation_pipeline.pl- Hippocampus and Amygdala segmentation scriptmiccai2012_segmentation_minipipe.pl- whole head segmentation pipeline, used in MICCAI 2012 Grand Challenge and Workshop on Multi-Atlas Labelingpatch_segmentation_pipeline.pl- generic segmetnation script used in RASCAL paper
All grading tools and scripts require library of labelled samples.
Similar to segmetnation tool, grading require library of presegmented examples $train and optionally search radius and patch radius
Training examples are referenced in a comma separated file in the format: <image.mnc>,<labels.mnc>,<grading>
Two training libraries can be provided , which are both loaded (and optionally each is used independently for pre-selection)
itk_patch_morphology input.mnc --grading output_grading.mnc --search $search_radius --patch $patch_radius --train $train --train2 $train2
