The general structure of the SW algorithm along with lossless decoder is p shown in Figure 4, that shows that the two different sources are encoded separately using a lossless encoder resulting in compressed outputs that are combined at the decoder end, as the scheme is based on joint decoding process with side information.
b) Encode this reduced-size image using one of the sequential DCT, progressive DCT, or lossless encoders described previously.
d) Use this up-sampled image as a prediction of the original at this resolution, and encode the difference image using one of the sequential DCT, progressive DCT, or lossless encoders described previously.
