inConnectivity | AvlNet.RegionConnectivity | Type of connectivity used for the region foreground. | |||
outRegion | AvlNet.Region | Output region. |
Description
The operation removes all internal pixels from the region (thus leaving only the boundary pixels). The definition of internal pixel depends on the inConnectivity value:
- If inConnectivity is set to Four directions, internal pixels are those having neighbours in all four major directions (up, down, left, right) also contained in the region
- If inConnectivity is set to Eight directions, internal pixels are those having neighbours in all eight directions (four major + four diagonal) also contained in the region
