habitat_region_stats

Note

This page is a reference documentation. It only explains the function signature, and not how to use it. Please refer to the Habitat Guide and Python API guide (v2.0) for usage.

habitat_region_stats(label_array: ndarray) → Dict[int, Tuple[int, int]]

Measure connected-component fragmentation per habitat.

Connected components use face connectivity, matching the SimpleITK ConnectedComponent default used by the v0.1 ITH implementation. The volume is cropped to the tumour bounding box first; that does not change region counts or sizes.

Parameters:

label_array – Integer habitat labels, 0 denoting background.

Returns:

Mapping of habitat id to (num_regions, largest_region_size) in voxels. Habitats absent from the array do not appear.
