region_size

region_size(im)[source]

Replace each voxel with the size of the region to which it belongs

Parameters

im (ndarray) – Either a boolean image wtih True indicating the features of interest, in which case scipy.ndimage.label will be applied to find regions, or a greyscale image with integer values indicating regions.

Returns

image – A copy of im with each voxel value indicating the size of the region to which it belongs. This is particularly useful for finding chord sizes on the image produced by apply_chords.

Notes

This function provides the same result as flood with mode='size', although does the computation in a different way.
