Use Sobel mask and find horizontal and vertical gradient outputs for the given 5x5 image matrix which is coded 4-bit/pixel. (Don't use padding operation, obtain your output matrix as 3x3 image size!) 3 22 13 11 323 12 3 1 11 1 13 10 13 12 13 14 12 14 12 14 2 1 12 13 2 a- Calculate the Gradient Magnitude Matrix? b- Calculate the Gradient Orientation Matrix?
