Abstract

A novel error-resilience tool for JPEG 2000 is proposed, based on the concept of ternary arithmetic coders employing a forbidden symbol. The proposed decoder extends the JPEG 2000 capabilities in error-prone scenarios, without violating the standard syntax, and extensive simulations on video sequences show that the proposed decoders largely outperform the standard in terms of PSNR and visual quality.

Abstract

Hybrid loss protection as a new channel of coding and packetization scheme for image transmission over nonprioritized lossy packet network is presented. A new code-allocation algorithm is proposed and the results are provided in the case of transmission of imagesencoded by SPIHT and JPEG 2000 over a wireline, as well as a wireless UMTS-based internet connection.
