- The edges are detected by applying a statistical filter that analyzes the variations of colors in a specified direction around each pixel.
- This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
- This command does not support 32-bit grayscale images.
