Compute horizontal, vertical, left, right profile of a character image

How to calculate left, right, top, and bottom profile of a character image of size MxN. That is outside distance between the bounding box of character image and the edge of the character. (on each row of each first encountered pixels from left for left profile, similarly for right, top, and bottom edges of bounding box.) I want to store it into arrays array equal to size M for left/right and N for top/bottom for image/character. Note:

Thanks

What's the difference between the top and bottom profile? To get vertical and horizontal profiles, use sum() or mean():

verticalProfile = sum(grayImage, 2);
horizontalProfile = sum(grayImage, 1);  % Or could use mean()

I did not express my problem well. I meant distance profile. Thanks

You could probably use the distance transform, bwdist().
