Consider the following 4*4 block of image f(x,y). (1) Calculate the DC coefficient and the first two AC coefficients i.e F(0,0), F(0,1) and F(1,0) of the block. The transformed block was lossless encoded and transmitted. (ii) Suppose the decoder is able to recover all coefficients in the transform block exactly except F(0.0) which was decoded as 36. Calculate what will be the pixel values in the reconstructed block. x y-> 1 V 10 0 0 0 0 100 0 0 0 0 0 0 0 0 0 10 Consider the following 4*4 block of image f(x,y).
