Simple Implementation of Canny Algorithm for Edge Detection.
Steps/Algorithm Details :
1. Convolution with Gaussian Filter Coefficient
2. Convolution with Canny Filter for Horizontal and Vertical orientation
3. Calculating directions using atan2
4. Adjusting to nearest 0, 45, 90, and 135 degree
5. Non-Maximum Suppression
6. Hystheresis Thresholding

Input image is in RGB.
Using two values for Thresholding, T_High and T_Low.
