Unequal error protection and progressive decoding for JPEG2000

This paper presents an unequal error protection scheme based on the Plotkin construction for channel (error control) codes. The resulting codes offer the novel ability of using one long channel codeword to protect an entire image, yet still allowing progressive decoding. Progressive quality improvements occur in two ways: the first is the usual progressive refinement, where image quality is improved as more data are received; the second is that residual error rates of earlier received data are reduced as more data are received.
