In this paper, we address the dependent joint bit allocation problem in H.264/AVC statistical multiplexing. In most existing methods, to improve the overall visual quality, the bit allocation is based upon the instantaneous relative frame complexity of different video programs. However, due to the temporal prediction employed in H.264, the influence of a frame on the rate-distortion (characteristics...
As one of the best image denoising methods, the Non-Local Means(NL-Means)algorithm[5] proposed by Buades et al. generates state-of-the-art performance. However, due to the high computational complexity, it is difficult to be directly used in practical applications. In this paper, a novel fast algorithm based on the similarity of spatially sampled pixels is introduced. Compared with other fast approaches,...
