Canny Edge Detection

Useful for Edge Detection based on Canny Edge Detection Method.

Description

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.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.7 (R2008b)

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.

Hi Gagan. I found a error in your code. The degree range of 'atand' is [-90,90]. Thanks.
