Image Refinement for Lossy Channels with Relaxed Latency Constraints
Numerous image coding approaches have been devised which result in high-quality reconstructions despite the presence of channel errors. This paper considers the case where a channel degrades to such a degree that decoder feedback must be applied in order for the reconstruction to be `acceptable'. It considers several means of generating refinement data, and applies these methods to a multi-channel coding technique previously dubbed `smoothed description coding'. Results are presented which demonstrate that satisfactory reconstruction quality can be attained in extremely lossy channels
