An improved decoding algorithm based on joint bitplane decoding for distributed video coding is proposed. The new algorithm uses the decoded bitplane results of quantization coefficients as prior knowledge, and decodes the other bit-planes to avoid correlation weakening between sources when decoding bit-planes independently. It makes full use of correlation between Wyner-Ziv frames and key frames; therefore the rate-distortion performance of distributed video coding can be enhanced without increasing decoding complexity. Simulations indicate that, compared with the independent bit-planes decoding system, the proposed algorithm can achieve 13% to 16% bit-rate saving under the same condition, and performance improves more apparently with the increase of quantization levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
