Side Information Refinement for Transform domain Distributed Video Coding
A new side information refinement method for transform domain distributed video coding (DVC) is proposed. In DVC, side information is the frame constructed from key frames which are intra coded. It is utilized as the initial estimate of source symbols of Wyner-Ziv coded frame which is not transmitted to the decoder. Errors in the estimated frames are to be corrected by the decoder using the par...
متن کاملSpatial correlation-based side information refinement for distributed video coding
Distributed video coding (DVC) architecture designs, based on distributed source coding principles, have benefitted from significant progresses lately, notably in terms of achievable rate-distortion performances. However, a significant performance gap still remains when compared to prediction-based video coding schemes such as H.264/AVC. This is mainly due to the non-ideal exploitation of the v...
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...
متن کاملTransform Domain Residual Coding Technique for Distributed Video Coding
Due to its lightweight encoder architecture, the Distributed Video Coding (DVC) concept has been seen as an attractive alternative to its conventional counterparts for a number of applications. Exceptionally low computational complexity has been achieved by moving redundancy exploitation to the decoder. However, going against this norm, redundancy exploitation techniques such as DCT transform a...
متن کاملTransform Domain Slice Based Distributed Video Coding
Distributed video coding depends heavily on the virtual channel model. Due to the limitations of the side information estimation one stationary model does not properly describe the virtual channel. In this work the correlation noise is modelled per slice to obtain location-specific correlation noise model. The resulting delay from the lengthy Slepian-Wolf (SW) codec input is also reduced by red...
