Dependency channel model for transform domain Wyner-Ziv coding
Distributed video coding is a new video coding paradigm aimed at shifting the computational expensive motion estimation to the decoder. Side information is generated at the decoder as a prediction of the current frame. This creates a virtual dependency channel between the source video at the encoder and the side information at the decoder. Error correcting channel codes are used to correct the ...
متن کاملFeedback Channel in Pixel Domain Wyner-ziv Video Coding: Myths
Wyner-Ziv (WZ) video coding – a particular case of distributed video coding (DVC) – is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems. Recently, practical WZ video coding solutions were proposed with promising results. Many of the solutions available in the literature make use of a feedback channel (FC) to perform rate control ...

متن کاملAdaptive Unequal Error Protection Based on Wyner–ziv Coding
Compressed video is very sensitive to channel errors. A few bit losses can derail the entire decoding process. Therefore, protecting compressed video is always necessary for reliable visual communications. In recent years, the Wyner–Ziv lossy coding theorem has been applied for error resilience and achieved superior improvement over conventional techniques. In our previous work, we proposed an ...
متن کاملTransform Domain Wyner-Ziv Video Coding with Refinement of Noise Residue and Side Information
Distributed Video Coding (DVC) is a video coding paradigm which mainly exploits the source statistics at the decoder based on the availability of side information at the decoder. This paper considers feedback channel based Transform Domain Wyner-Ziv (TDWZ) DVC. The coding efficiency of TDWZ video coding does not match that of conventional video coding yet, mainly due to the quality of side info...
