Abstract: |
Efficient intra prediction is an important aspect of video coding with high compression efficiency. H.264/AVC applies directional prediction from neighboring pixels on an adjustable block size for local decorrelation. In this paper, we present an extended prediction scheme in the context of H.264/AVC that comprises two additional prediction methods exploiting self-similar properties of the encoded texture. A new macroblock type is implemented, allowing for flexible selection of the available prediction methods for sub-partitions of the macroblock. Depending on the content of the encoded video sequence, substantial gains in rate-distortion performance are achieved. The results may indicate directions towards an enhanced intra coding scheme with improved rate-distortion performance. |
