To solve the fuzzy edge detection problems in image processing, a novel fuzzy clustering method based on chaos small-world algorithm (CSWFCM) is presented. The traditional fuzzy clustering method (FCM) is good at local searching capability, but it is sensitive to the initial value and easy to trap into local minimum value. The small-world algorithm (SWA), inspired by the mechanism of small-world phenomenon,...
Rate distortion optimization (RDO) based spatial intra prediction is an important new feature in H.264/AVC. It chooses the best mode for each MB by exhaustively examining all possible modes. Thus,drastically increased computation complexity is involved. This paper proposes an efficient fast intra mode decision algorithm.Prewitt operator is used to extract each block's two most dominant edge directions...
