Abstract :
This work describes a method for providing robustness to errors from a binary symmetric channel for the JPEG2000 (J2K) image compression standard. It does so while maintaining full J2K compliance. The source rate and channel rate are jointly optimized by using a Viterbi Algorithm (VA) on a stream of fixed-size channel packets, such that the rate allocation complexity grows O(N2) with the number of transmitted packets. Punctured turbo codes are used for the channel coding, providing stronger error protection than previously available codes. The rate allocation scheme presented obtains all necessary information from the J2K encoder, and does not require image decompression
