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

What you are asking for can be done all though it does require advanced programming capabilities, first you must write a function that detects all the pixels that have been changed due to the edge detection function and use a Gaussian algorithem to calculate each pixels distance from all the other pixels.

This is not recommended for beginners using MATLAB. Good luck

Thank you for the quick reply.
How many hours would it take to write that code? Tamir.

About 20-30 hrs. for a seasoned programmer.

if you use images in the form of matrices and command like d(i,j)=sqrt((y2(i,j)-y1(i,j))^2+(x2(i,j)-x1(i,j)^2) then it becomes easier.i am not sure but try this one.
