H.264/MVC is the latest video standard for three-dimensional video compression. Similar to H.264/AVC, H.264/MVC carries out the compression for multi-view image system to achieve the more compression efficiency. This paper focuses on the inter-view redundancy reduction in disparity prediction. For disparity estimation, this paper produces a more accuracy disparity vector predictor and narrows down...
This paper presents two low complexity macroblock-level MAD (Mean Absolute Difference) prediction algorithms for H.264/AVC rate control. Both of the algorithms consider the rate-distortion performance and its hardware cost jointly. One of the algorithms predicts the MAD value by observing the motion vector of the surrounding macroblocks (MB), the other one uses numerical analysis to find the best...
In this paper, an efficient mode decision algorithm and a high throughput hardware architecture with eight-pixel parallelism for improving the H.264/advanced video coding intra coding efficiency are proposed. Based on the inherent features of the discrete cosine transform, the input block is first transformed and then analyzed to determine its texture directional tendency. A few candidate modes are...
H.264, MPEG-4 Part 10, is the latest digital video coding standard that is noted for achieving very high data compression by using several new coding features. One of the key features is the intra prediction based on the rate distortion optimization (RDO) procedure, which requires a true encoding of the intra block by trying all intra prediction modes. The computational burden of intra prediction...
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...
