The Canny Edge detection method relies on various steps:
1. Convolution with Gaussian.
2. Estimation of Gradient Vector.
3. Non Maxima Suppression.
4. Thresholding and Connectivity Analysis.
Good job. but matlab already has 'edge'...
Hi all, I am very interested in this code, I am using it to measure how it is the dilatation of metal samples and taking pictures. I convert the picture to BW format only binary, to see in pixel precision the edges. What I want to know, is measure the space in a straight line between two pixels, by doing this in the picture, handling for instance. Like Autocad does with the magnetic cursor, make a cursor or something like that, sensitive to pixel precision and take measures in a easy way. Tell me if you have an idea by email.
Thanks you at all.
Hi Gagan. I found a error in your code. The degree range of 'atand' is [-90,90]. Thanks.
Hi Gagan, would you explain what the input arguments are. I'm familiar with only the basics of edge detection so it'd be helpful if you could explain them and also give some examples if possible.
