Detailed Description

Calculates the volume and centroid for each label in a labeled image.

Labels are expected to be of an unsigned integer type. The class iterates over all voxels, groups them by label value, and computes each label's volume (voxel count * voxel volume) and centroid (center of mass).

Note

Currently only the first time step of the image is processed.
