segmentations_merge

petpal.preproc.segmentation_tools.segmentations_merge(segmentation_primary: numpy.ndarray, segmentation_secondary: numpy.ndarray, regions: list) → numpy.ndarray

Merge segmentations by assigning regions to a primary segmentation image from a secondary segmentation. Region indices are pulled from the secondary into the primary from a list.

Primary and secondary segmentations must have the same shape and orientation.

Parameters:

• segmentation_primary (np.ndarray) – The main segmentation to which new regions will be added.

• segmentation_secondary (np.ndarray) – Distinct segmentation with regions to add to the primary.

• regions (list) – List of regions to pull from the secondary to add to the primary.

Returns:

segmentation_primary (np.ndarray) –

The input segmentation with new

regions added.
