Features from habitat maps

HABIT-native definitions, formulas, and output CSV columns for features extracted on habitat maps (after habitats exist). Intensity / texture / shape radiomics follow IBSI definitions as implemented by PyRadiomics (3-D averaged texture). ROI-level radiomics, voxel-level radiomics, and 3-D shape match FeatureExtractor.execute() — see PyRadiomics alignment on Traditional Radiomics. Official digital-phantom numbers: Traditional Radiomics. PyRadiomics catalogue: PyRadiomics Feature Reference.

Each page: Output → Definition → Formula (if any) → Output columns → Implementation → References (if any).

Light built-in families (volume, msi, ith_score, graph) are peers in feature_types. Topology walk-through: Graph features. CLI / YAML bookmark: Graph topology features.

Voxel-level texture used as habitat inputs (voxel_radiomics) is a different product surface — slice figures live under Voxel texture and GPU, not as a feature_types CSV family. Registered extractor names (input side and map-side): Habitat Spec component catalog.
