Description
The operation removes all boundary pixels from the region (thus leaving only the interior pixels). The definition of boundary pixel depends on the inConnectivity value:
- If inConnectivity is set to Four directions, boundary pixels are those having at least one of the neighbours in four major directions (up, down, left, right) not contained in the region
- If inConnectivity is set to Eight directions, boundary pixels are those having at least one of the neighbours in all eight directions (four major + four diagonal) not contained in the region
