def _convert_segmentation(segmentation, mask_targets, mask_types, converter): (source)

Convert segmentation to a collection of detections, polylines, etc.

converter(label_mask, label, label_type, offset, frame_size) is a function that returns a list of detections, polylines, etc. It gets called for each value in mask_targets, or for all values in the mask if mask_targets is None.

def _find_slices(mask): (source)

Return slices that tightly bound each unique object in mask.
