dist=sqrt((y2-y1)^2+(x2-x1)^2);%%%% Where (x1,y1) and (x2,y2) are coordinates of two pixels

hello, i actually have a followup question, I am trying to find a way to calculate the distance between edges of an image created by edge detection toolbox. The edges are painted white on the image, and i need to somehow calculate the distance automatically between the longest distance of each edge. For example if the edge is a square - i would like to calculate the width and length of it.

Thank you Tamir
