In this paper, we present an efficient side information extrapolation scheme with temporal and spatial consistency for low-delay Wyner-Ziv video coding. Our method is based on the regularized local linear regression (RLLR) model, in which each pixel in SI is approximated as a linear weighted combination of samples within a local temporal neighborhood. The optimal model parameters are estimated by...
Intra prediction is one effective method to remove the spatial redundancies in intra frame coding. Better intra prediction will result in the residual with less energy, which will decrease the number of bits needed to reconstruct the signal at decoder. To improve the accuracy of intra prediction, a context-adaptive pixel based prediction (CAPBP) algorithm is proposed in this paper. For each pixel...
