Abstract :
In the state of the art hybrid video coding structure, intra prediction and transform coding are the most important two parts for intra picture coding. Generally, the prediction process and the transform process are separated. The current block is first predicted from the neighboring reconstructed pixels, the residue block is then transformed. In our approach, the prediction process and transform process are combined, therefore more information can be used for prediction and more accurate prediction can be achieved.
