%Some parts of code obtained from %http://math.gmu.edu/~tsauer/class/447/proj/chap11.pdf function Xc = dequant(Y,C,Q) Xc = Y.*Q; % multiply each value by quantization matrix Xc = C'*Xc*C; % perform inverse 2D-DCT Xc = Xc + 128; % put pixels to original values
Not enough input arguments. Error in dequant (line 5) Xc = Y.*Q; % multiply each value by quantization matrix
