MATLAB: X,y coordinates of edge lines in image ?

Question

Dear all,

I've got edge of image as follows.
          I=imread('edge.png');
          I=rgb2gray(I);
          the_edge = edge(I);

Now I need to get the x,y coordinates of edge lines in image.Can anybody suggest an idea ?

Answer 1

[y, x] = find(the_edge);
