We are using sobel edge detection in our application. It is working fine.  we got this sobel code from the analog devices .  In the sobel code they are making boundary pixels as zero(i,e first row ,last row, first and last elements of each row). But in our application we don't want the boundary pixels to become zero. So can you tell me what are the changes we have to do for the current code. I am attaching the sobel code here
