Detailed Description
SoRegionToObjectProcessing2d image filter
The SoRegionToObjectProcessing2d engine transforms an object image into a region image.
The SoObjectToRegionProcessing2d engine scans the image from top to bottom and left to right. The algorithm works in two steps:
- The first scan detects the boundaries between regions and creates a real boundary with gray level at 0.
- The second step applies the SoLabelingProcessing engine.
