PLEASE HELP. THANKS IN ADVANCE

1. [DCT] Please consider the following set of DCT basis for 8px by 8px images. They are arranged, in general, in increasing spatial frequency. WW O WWW a) Let us call the basis function in the upper-left corner (0,0) and upper-right corner (7,0). By inspection, which THREE basis functions will likely to have a large coefficient amplitude if we were to encode the following image (an enlarged 8px by 8px image)? Explain your guess for EACH of the choices. b) Estimate coefficients of the 3 basis functions of your choice in (a). What will the reconstructed image look like if we only use them to encode the image? Please do a rough sketch. 1. [DCT] Please consider the following set of DCT basis for 8px by 8px images.
