This paper presents an adaptive weighted distortion optimization algorithm used in the Rate-Distortion Optimization (RDO) process of the High Efficiency Video Coding (HEVC). RDO is an important tool to improve the coding efficiency. Usually the distortion weights of different color components are equal or predetermined. In this paper, an adaptive weighted distortion optimization algorithm is introduced...
This paper presents the results of compression comparison tests between the current state of the emerging High Efficiency Video Coding (HEVC) draft standard and the current dominant standard H.264/MPEG-4 AVC (High Profile) as an anchor reference. The conditions used for the comparison tests were designed to reflect relevant application scenarios and to enable a fair comparison to the maximum extent...
Distributed compressive sensing (DCS) is a new technique that provides a low-complexity sub-Nyquist signal acquisition and reconstruction via a small number of random linear projections. In this paper, we propose sparse filter correlation model (SFCM) to exploit the correlations among successive video frames under the framework of distributed compressive video sensing (DCVS). At the central decoder,...
In this paper, we propose a novel scheme using computing complexity layered scalable video coding (CCLSVC) to optimize the user experience of broadcasting video in the computing capability limited handheld terminals. To address the heterogeneity of computing capability among different handheld devices, we employ hierarchal B reference structure of SVC to divide the frames into multiple computing complexity...
