A Novel Rate-Distortion Method in 3D Video Capturing in the Context of High Efficiency Video Coding (HEVC) in Intelligent Communications
Résumé
High-Efficiency Video Coding is currently proposed as the newest and most efficient video coding standard by the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Compression improvement relative to existing standards is estimated in the range of 50%. It is a block-based hybrid video coding algorithm that introduces several novel features compared to MPEG-4 like Coding Units associated with Prediction Units and Transform Units, Advanced Motion Vector Prediction, minimization of a rate-distortion Lagrangian cost, directional orientations for intra-picture prediction etc. The core algorithm of Context-Adaptive Binary Arithmetic Coding is based upon that of the MPEG-4 standard. View synthesis algorithms for HEVC stereo and 3D encoding are expected to be finalized as a standard extension. A Multi-view Video Coding scheme based upon the estimation of correlated parameter sets of elastic models between views is wherein adopted. The order of the tensor equals the number of multiple views. Underlying distributions are updated step-by-step. They are modeled according to context indices.
