7. (a) Explain non-maximum suppression as proposed in Canny edge detection. (b) Canny edge detection applies Sobel operators to calculate the gradients. What will be the effect to the detected edges of reversing the signs of the Sobel operators e.g. -1 to 1, -2 to 2, and vice-versa? Explain your answer with an example.
