Information Re-use and Edge Detection In Intra Mode Prediction

摘要：

In intra mode prediction. obtaining the best solution among all supported modes requires extremely high com putation. Most fast search algorithms use a reduced search set to avoid this problem. Yet these methods greatly degrade picture quality and increase bitstream size if very limited computational resource is applicable. In this paper, we proposed a scheme, which allows us to take extensive advantage of correlation within a video sequence. Prediction errors and modes of neighboring blocks are employed in our mode prediction scheme. The proposed method can either work alone or with existing direction detection methods to significantly reduce computation without losing much performance.
