We propose a Taylor- series-based rate-QS model and a scene-change aware rate-QS model to determine quantization parameters for general intra- frames and scene- ...
Abstract—Most of rate-control researches focus on inter-coded frames, instead of intra-coded frames which are more possible to.
This letter presents a rate control algorithm for intra-frame coding. We propose a Taylor-series-based rate-QS model and a scene-change aware rate-QS model to ...

IEEE Transactions on Circuits and Systems for Video Technology · Year : 2010 Volume : 20 · Issue 12 · Scene Change Aware Intra-Frame Rate Control for H.264/AVC.
In this work, a scene change is detected by comparing the ratio of the sum of absolute difference (SAD) between two consecutive frames. As the scene change is ...
Abstract: In this paper, a coding tree unit (CTU)-level rate control (RC) scheme is proposed for intra-frame coding in the high efficiency video coding ...
As the scene change is detected, the proposed method, which is modified from the ref- erence software of H.264/AVC, re-assigns a quantization parameter (QP).
