  Abstract

In H.264/AVC, rate distortion optimization algorithm is used to decide the best block mode from various block modes. It improves a bit rate but greatly increases an amount of computation. This paper proposes a fast rate distortion optimization algorithm that omits a rate distortion optimization adaptively by predicting its cost from the cost calculated for motion estimation. The simulation results show that the proposed algorithm, on average, keeps nearly the image quality and the bit rate made by the rate distortion optimization while reduces 69.86% and 69.63% of computation added by it in CIF and QCIF respectively.
