I am able to find the edges of an image using sobel or canny filter. But I cant calculate the width of the edges.
Actually I want to do the following:
find the width of all horizontal and vertical edges and sum up altogether and store in a variable, say W1
Then find the width of other (non horizontal and vertical) edges. Then multiply each edge width by a factor sqrt(2). After sum up altogether and store in a variable say w2.
Finally perform (w1+w2)/N where N is the no of total edges in the image.

Looks like I responded to that 3 weeks ago and you never replied.

Oh, I'm really sorry, I just saw your response. I will reply in that thread. Thanks.

First I'd threshold ats some desired edge strength. Then I'd use bwmorph() to get the skeleton of the edges and call sum() to get the length. Then I'd call bwarea() on the thresholded image to get the area. Divide the area by the length to get the average width of all the edges.
