Wavelet-based image codecs, such as SPIHT and JPEG2000, have shown to be superior to DCT-based image codecs in not only the coding efficiency but also the functionalities such as the progressive property, which allows the bit stream to be truncated in any position and thus provides rate scalability. Although the progressive image coding can provide excellent compression and scalability performance, it makes image bit streams very sensitive to channel noise. Therefore, how to robustly transmit progressive image over lossy channels becomes an important issue and has received much attention in the past a few years.
