filter_by_volume — 3D `regionprops` op

• Data kinds: voxel → voxel

• Call: import regionprops3d; regionprops3d.filter_by_volume(vol, min_voxels: 'int', connectivity: 'int' = 26) -> 'np.ndarray' (or ops3d.get("filter_by_volume"))

Usage

Return a bool mask with the connected components below min_voxels removed.
