This paper proposes an Iterative Joint Source–Channel Decoding (IJSCD) scheme for error resilient transmission of H.264 compressed video over noisy channels by using the available H.264 compression, e.g., Context-based Adaptive Binary Arithmetic[...]

In the joint multiview video model (JMVM) proposed by JVT, the variable block-size motion estimation (ME) and disparity estimation (DE) have been employed to determine the best coding mode for each macroblock (MB).
These give a high coding effi[...]

There is currently limited flexibility for distributing complexity in a video coding system.
While rate-distortion-complexity (RDC) optimization techniques have been proposed for conventional predictive video coding with encoder-side motion est[...]

In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients.
A hierarchical classification map is defined in each wavelet subband, which describes the qua[...]

Adaptively selecting the filter coefficients for interpolating fractional pixels (sub-pel) can significantly improve the quality of reference pictures.
However, the complexity of implementation is greatly increased by performing motion estimati[...]

This paper presents a novel approach that performs post-processing for stereo matching.
We improve the performance of stereo matching by performing consistency check and adaptive filtering in an iterative filtering scheme.
The consistency chec[...]
