Abstract

The standard H.264/AVC Intra frame encoding process has several data dependent and computational intensive coding methodologies that limit the overall encoding speed. It causes not only a high degree of computational complexity but also an unacceptable delay especially for the real-time video applications. In this article, high throughput Full-Search Free (FSF) Intra mode selection and direction prediction algorithm is proposed based on DCT properties and spatial activity analysis. It significantly reduces the computational complexity and the processing run-time required for the H.264/AVC Intra frame prediction process. The empirical results using standard benchmark frames showed that the proposed FSF Intra prediction algorithm not only significantly reduces the computational complexity but also speeds up the Intra prediction operation with a factor of x2.2 at a slight PSNR degradation of less than 1.8% When compared with the Intra prediction algorithm currently used in the H.264/AVC standard software JM 18.2 while keeping the same bit rate.
