WebJan 27, 2024 · JPEG decoding is essentially the reverse process. Note that we say that step 4 is lossy because it can’t really be undone. We know what the quantization matrix used to divide the coefficients was, but because the coefficients were rounded, when we multiply we only get an approximation of the original coefficients.
