A novel weighted cross prediction for H.264 intra coding

In this paper, a novel weighted cross prediction (WCP) mode is proposed to replace DC mode in Intra_4times4 prediction of H.264/AVC. In the proposed scheme, the upper right part of one 4times4 block mainly employs vertical prediction while the lower left part mainly uses horizontal prediction, predicting both in vertical and horizontal directions in one block. This scheme uses simple prediction equations with fixed weighting coefficients. Experimental results show that WCP has improvement compared to H.264 and it is very competitive while comparing to other Intra_4times4 prediction algorithms.
