habit.voxel_features: per-voxel descriptors

Built-in voxel feature extractors and their registry.

User guide: Habitat Guide Voxel features · Voxel texture and GPU · Habitat domain API. Component names: Habitat Spec component catalog.

raw / local_entropy / voxel_radiomics describe each ROI voxel; concat / expression / kinetic compose those families. extract_voxel_texture() is the same voxel_radiomics pass on one ImageVolume + mask (no Subject).

Classes

VoxelFeatureExtractor	Turn a subject's images into per-voxel feature vectors inside the ROI.
RawVoxelFeatures	Per-voxel raw intensity of every requested modality inside the ROI.
LocalEntropyVoxelFeatures	Shannon entropy of each voxel's intensity neighbourhood.
VoxelRadiomicsFeatures	Describe every ROI voxel by a PyRadiomics feature vector.
ConcatVoxelFeatures	Join several voxel feature families side by side for the same voxels.
ExpressionVoxelFeatures	Per-voxel features defined by restricted arithmetic expressions.
KineticVoxelFeatures	Per-voxel enhancement slopes across a dynamic contrast series.
VoxelFeatureTree	Evaluate a voxel-level feature tree into one VoxelFeatureField.
VoxelFeatureExtractorRegistry	Name-to-implementation registry for voxel feature extractors.

Functions

extract_voxel_texture	Extract a per-voxel texture table from one image and one mask.
build_voxel_extractor	Build one voxel-level node: a leaf extractor or a combiner tree.
build_voxel_field	Assemble a VoxelFeatureField with provenance for one subject.
aligned_image	Read one modality after ensuring it shares the ROI's voxel grid.
roi_voxels	Return the ROI mask together with its boolean selector and coordinates.
load_cached_voxel_field	Load a cached field when the archive exists and is readable.
save_cached_voxel_field	Write field under the cache key (atomic replace).
voxel_radiomics_cache_key	Hash the settings that change voxel-radiomics numbers.
voxel_volume_fingerprint	Hash the image and mask arrays that enter voxel radiomics.
