- Abstract
- In this paper, we proposed a fast intra prediction algorithm for H.264/AVC. Although the H.264/AVC achieved superior coding performance compared with previous video coding standards, the coding computational complexity is also considerable. To reduce the complexity, we select proper candidate intra prediction modes using the angle of the pixel differences along the horizontal and vertical direction to be involved in the RDO, and it results in around 77% of encoding time reduction with negligible coding performance loss. Thus, the proposed algorithm can be utilized usefully for real time high quality high quality video application.
