Abstract
Generalized multiple description coding (GMDC) is source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may pro- duce a useful reconstruction. This paper reports on ap- plications of two recently proposed methods for GMDC to image coding. The first produces statistically correlated streams such that lost streams can be estimated from the re- ceived data. The second uses quantized frame expansions and hence is conceptually similar to block channel coding, except it is done prior to quantization.Keywords
