Paper Abstract

When transmitting image information through a channel, the image data is sometimes corrupted by different error sources. To deal with these error issues found in different types of transmission channels, JPEG-2000 has developed several error resilience tools that can be used to improve the decoding performance in the presence of errors. The error resilience tools currently available include resynchronization markers, short packet headers, arithmetic coding bypass, arithmetic coder termination and context reset, and segmentation symbols. Resynchronization markers enable the decoder to re-establish synchronization even when bit errors occur within a packet. Short packet headers provide the ability to move the header information within a packet into the tile or main header. Arithmetic coding bypass allows arithmetic coding to be stopped and raw data to be placed within the bitstream instead. The propagation of errors is reduced through arithmetic coder termination and context resetting, since the arithmetically coded bitstream is divided into independent coder elements through these methods. The addition of segment symbols within the bitstream at the end of each bitplane allows errors to be detected within the coded bitplanes of the code blocks. This document gives a description and performance evaluation of the error resilience tools within JPEG-2000.
