Motion modeling for motion vector coding in HEVC

Michael Tok, Volker Eiselein, Thomas Sikora
2015 2015 Picture Coding Symposium (PCS)  
In this paper a general motion model based vector coding scheme is introduced.  ...  This scheme includes estimation, coding and dynamic recombination of parametric motion models to generate vector predictors and merge candidates for all common HEVC inter coding settings.  ...  In such cases it is better to use a higher order motion model for motion vector prediction rather than for motion vector coding.  ...

RBF-Based QP Estimation Model for VBR Control in H.264/SVC

Sergio Sanz-Rodriguez, Fernando Diaz-de-Maria

Two-Dimensional Shape Coding [chapter]

Joern Ostermann, Anthony Vetro
2006 Signal Processing and Communications  
Coding algorithms like objectbased analysis-synthesis coding (OBASC) [30| use shape as a parameter in addition to texture and motion for describing moving video objects.  ...  This results in a new dimension of interactivity and flexibility for standardized video and multimedia applications.  ...  The parameter coder first encodes the shape of the boundary blocks using shape and texture motion vectors for prediction. Then, shape motion vectors are coded.  ...

A Rate Control Algorithm for Scalable Video Coding

Long XU, Wen GAO, Xiang-Yang JI, De-Bin ZHAO
2009 Chinese Journal of Computers  
This thesis proposes a rate control (RC) algorithm for H.264/scalable video coding (SVC) specially designed for real-time variable bit rate (VBR) applications with buffer constraints.  ...  This in-layer multibuffer framework for rate-controlled SVC does not require additional dependency layers to deliver different HRD-compliant temporal resolutions for a given video source, thus improving  ...  It should be noticed that the ∆QP (d) prediction model is a part of the RC scheme, so the overall system should be evaluated in a practical coding scenario.  ...
