Hi
I need to find the surrounding edge of a region. I used these lines but it don't give me a good result . log find an edge belonging to the region when I need to find the edge that surrounds the region. Is there a matlab function that extends the edge given by log 1 or 2 pixels
I=imread('image.jpg');
edg = edge(I,'log',0);
thankx
