A Constant Quality Coding Framework for H. 264/AVC  
Abstract Quality control is important in video coding, which tries to dynamically adjust the encoder parameters for achieving the target distortion. In this thesis, we propose a quality control framew......

RBF-based QP estimation model for VBR control in H. 264/SVC  
Abstract In this paper, we propose a novel variable bit rate (VBR) controller for real-time H. 264/scalable video coding (SVC) applications. The proposed VBR controller relies on the fact that consecu......

window-level rate control for smooth picture quality and smooth buffer occupancy  
Traditionally, rate control consists of bit allocation and QP decision on R-QP model. In bit allocation, target bits is further confined if buffer overflows. Meanwhile, rate control should also give a......

TWO-PASS RATE CONTROL FOR CONSTANT QUALITY H.264/AVC HIGH DEFINITION VIDEO CODING  
In this paper, we propose a novel rate control algorithm that adopts two-pass encoding to provide constant quality for H.264/AVC high definition videos. In the first-pass encoding, the rate and distor......

An efficient algorithm for H. 264/AVC high definition video coding  
Abstract Quality consistency has been an important issue in video applications. However, the quality fluctuation cannot be avoided in single pass video coding due to the variation of the video content......
