The pgm file can be accessed with the following website http://web.eecs.utk.edu/~qi/ece315/project/cameraman.pgm 2. (30 pts) Comparison of performing convolution in the spatial vs. frequency domain. Convolve http://web.eecs.utk.edu/-qi/ece315/project/ cameraman.pgmcameraman.pgm with convolution kernel h i.e., a 2-D impulse response using both spatial domain method (using the MATLAB function conv2)) and frequency domain method (see details below). Compare the results both visually and by reporting the execusion time. Use the MATLAB function tic and tac. . Generate convolution kernels of different sizes (e.g.. 7×7,25x 25, 49x 49, etc.)
