This paper proposes a unidirectional encoder rate control (ERC) scheme in the interpolation based distributed video coding. As the encoder is complexity constrained, accurate estimation of number of bits to decode each bit plane is indeed difficult at the encoder. In case of under-estimation of the bits, correction of the errors in the decoded bit planes, by utilizing the available information, is...
Distributed Video Coding (DVC) provides a new coding paradigm based on lower complex encoders than decoders. On the decoder side some missed frames have to be estimated by means of available frames and a correlation noise model. In addition, parity bit chunks can be requested to the encoder across the feedback channel to correct the mismatches of these frames. This is an iterative procedure which...
In most Wyner-Ziv video coding approaches, the temporal correlation of key frames is not exploited, since they are simply intra encoded and decoded. In previous work, by using the previously decoded key frames as the side information, we proposed to divide the frequency bands of each block into two classes. Wyner-Ziv coding was used for the low frequency bands of each block, while high frequency bands...
Traditional multiview video coding schemes exploit all types of correlations at the encoder. The inherent high encoder complexity and the needs for large volume data communication between cameras make them impractical for many applications. In this paper, we propose a novel distributed coding scheme for multiview video. All the views are separately encoded but jointly decoded. At the decoder, we design...
Low-complexity video encoding has been applicable to several emerging applications. Recently, distributed video coding (DVC) has been proposed to reduce encoding complexity to the order of that for still image encoding. In addition, compressive sensing (CS) has been applicable to directly capture compressed image data efficiently. In this paper, by integrating the respective characteristics of DVC...
Distributed video coding has become increasingly popular in recent years among the researchers in video coding due to its attractive and promising features. DVC proposed a dramatic structural change to video coding by shifting the majority of complexity conventionally residing in the encoder towards the decoder. Nevertheless, these kinds of architectures have some serious limitations that hinder its...
