Abstract

In this paper, an algorithm for improving image quality with original optimized rate-distortion extraction mechanism in the scalable extension with H.264/AVC is proposed. In our algorithm, the importance of the first MGS (medium grain scalability) layer was thought higher, thus we carry more weight on it when estimating quality information and assigning priority IDs. In our experiment, the PSNR (peak signal-to-noise ratio) is really improved after extracting the encoded bitstream with inserted quality information by our proposed algorithm.
