Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inRegion | const Region& | Input region | |||
inConnectivity | RegionConnectivity::Type | Region connectivity semantics | |||
inMinHoleArea | int | 0 - | 1 | Minimal area of a hole | |
inMaxHoleArea | Optional<int> | 0 - | NIL | Maximal area of a hole | |
outNumberOfHoles | int& |
Description
The operation computes the number of region holes. Holes of a region are those connected areas of pixels not belonging to the region, that do not touch the boundary of the region frame.
