Abstract

Features of the JPEG2000 compression standard include coding efficiency at low bit rates. However, its compressed bit stream is sensitive to transmission error. This paper presents three techniques to reduce both the computational complexity and the memory requirement in the ternary MQ arithmetic decoding. Such coders introduce a controlled degree of redundancy during the encoding process, which can be exploited at the decoder side in order to detect and correct errors. Our proposed techniques result in a substantial saving of decoding time and memory usage, with no or little degradation in the PSNR metric.
