A novel decoder architecture for error resilient JPEG2000 applications based on MQ arithmetic

In this paper we investigate the complexity of a modified MQ arithmetic decoder architecture for error resilient JPEG2000 applications, based on the concept of ternary arithmetic decoder employing a forbidden symbol. Such ternary coding schemes have been already investigated to prove its excellent figures in terms of both PSNR and visual quality. However the complexity of the modified MQ decoder and its impact on real implementations has not been considered yet. In this paper an architectural analysis is performed and an optimized architecture is proposed.
