Canny edge detection of a total of four parts:
1. the original image with Gaussian smoothing
2. the Sobel edge detection of the Gaussian-smoothed image. Also need to maintain horizontal and vertical joint, so a total of three needed Sobel edge detection image.
3. Joint Sobel test image for non-maximum suppression
4. connection points and hysteresis thresholding.
