Techniques for modeling the background of a video sequence can be useful in alternative video coding approaches. Sprite coding has been evolved to provide high quality decoded video frames after transmission by a reduced amount of bits. However, it has also been shown that this works only for a certain kind of video sequences. It also meets quality limits due to the Sprite generation step. To tackle...
This paper presents an enhanced rate control scheme for H.264 using motion detection and motion analysis. PSNR based measure is used for determining motion complexity and detecting scene changes. Motion vectors and rate distortion measures are further used to classify regions with motion inside a frame and macro-blocks are then grouped into slices using the flexible macro-block ordering feature of...
This paper presents a fast intra/inter frame coding algorithm. In H.264/AVC prediction, the rate distortion optimization technique with full mode search is used to select the best mode for each macroblock. To reduce the computational load in mode decision, for intra frames discrete wavelet method used to filter low-pass data; for inter frames the intra mode is skipped according to the motion vector...
