version 1.0 (3.09 KB) by

The code computes the edge map for a grayscale image using canny detector



View License

The code is divided as:

1. Smooth the input image with a Gaussian filter.
2. Compute the gradient magnitude and angle images.
3. Apply nonmaxima suppression to the gradient magnitude
4. Use double thresholding and connectivity analysis to detect
the link edges.

Running the code:

[Ioutput]= cannydetector(I);
