A Novel Rate Control Algorithm Based on <i>ρ</i> Model for Multiview High Efficiency Video Coding

Most existing rate control algorithms are based on the rate-quantization (R-Q) model. However, with video coding schemes becoming more flexible, it is very difficult to accurately model the R-Q relationship. Therefore, in this study we propose a novel <i>&#961;</i> domain rate contro...
