| Abstract: |
Intra prediction is an effective method for reducing information in image and video coding. A sample predictor block is created by extrapolating the reconstructed pixels surrounding the target block to be coded. This is subtracted from the target block and the resulting residual coded using transformation, quantization and entropy coding. However the extrapolation method is not able to represent sample prediction blocks with complex texture. Furthermore, pixels that are far from the surrounding pixels are usually badly predicted. In this paper, a new method for sample predictor creation by template matching in a region of reconstructed pixels is presented. Improvements in coding efficiency by more than 11% in bitrate were achieved. |
