AForge.NET framework provides number of edge detection filters, which may suite different tasks
providing different performance.
Below is the list of implemented edge detection filters and the result of their application to the below source
image.

Homogenity Edge Detector
The filter finds objects’ edges by calculating maximum difference of processing pixel with neighboring pixels in 8 direction.
Difference Edge Detector
The filter finds objects’ edges by calculating maximum difference between pixels in 4 directions around the processing pixel.
Sobel Edge Detector
The filter searches for objects’ edges by applying Sobel operator.
Canny Edge Detector
The filter searches for objects’ edges by applying Canny edge detector.
