MaskRelate

Relates objects from two masks defining parents and their children objects. Children that ovelap with a parent object are given a number to refer to the parent. Children without parents get 0 value as the parent. As a default, children overlapping with multiple parents get the parent with most overlapping pixels. The value is 0 if most overlap is with no parent. In the output, you will find the relative areas of intersection to parent, child, and union objects.

names ImageList Optional A directory with the original image files, for naming the table. If omitted, names from "dir" are used.

Outputs

Name Type Description
out CSV List of relation values.
overlap ImageList Visualization of the parent-child relation.

Parameters

Name Type Default Description
emptyParents boolean true Add a 0 child for each parent that has no children at the end of table.
method string "Most" Method to solve children overlapping the edge of parent. Child may overlap with several parents, or with background. Methods to use: Most will select the parent with most overlap. Discard will set the parent 0 at any overlap situation. Any will select non-zero parent with most overlap.
