would like to know the algorithm of edge detection

It's hard to find the mathematic algorithm about the edge detection. I find that the Fourier transform of first derivative has been used. But anyone can post the algorithm on? thx

Hi mahone,

 

It's hard to find the mathematic algorithm about the edge detection.

What exactly is the problem?

Best regards,
