1) Write a Matlab function that takes as input a grayscale image and an integer n, then (1) partitions the image into 8x8 blocks, (2) computes the 2D-DCT of each block, (3) sets the last n DCT coefficients in each block to zero (choose the last coefficients according to the raster scan), (4) computes the inverse 2D-DCT of each block of coefficients, and (5) plots the resulting image

2) 2) Repeat 1) but replace the raster scan by the JPEG zig-zag scan and compare the PSNR for the two scans when the input image is ‘[login to view URL]’ and n = 48.
