Abstract
Reliable reception of still images is imperative in providing robust multimedia transmission over networks offering non-guaranteed transmission, such as ATM and other packet-based networks, satellite channels, and wireless networks. Not only are images used in home-shopping catalogs and on-line information services, but they also form the anchor frames for many video coding algorithms, notably MPEG and H.261. When considering digital image coding, generally the rate-distortion curve is the predominant criteria for measuring the goodness of an algorithm — an algorithm that produces a high PSNR at a high compression ratio is desirable. However, when such a compressed stream is segmented into packets and transmitted over an unreliable network, packet loss can have catastrophic consequences. Depending on the type of source coding employed and the information lost, damaged images may exhibit large segments of missing data, aliasing, or generally poor quality. Robustness is therefore vital for digital image transmission.
