Unformatted text preview: image using the modified DCT coefficients. (for a given mask, “1” indicates to retain that coefficient, “0” means to set the corresponding coefficient to zero) What effect do you see with each mask and why? = = = = = = 1 1 , 1 , 1 , 1 , 1 , 9 1 1 9 5 4 3 2 1 W W W W W S 2. For the same image S as given in Prob. 1, quantize its DCT coefficients using the quantization matrix Q . Determine the quantized coefficient indices and quantized values. Also, determine the reconstructed image from the quantized coefficients. = 5 3 3 3 Q...
