Research on a novel model for intra-skip in inter coding
Ning Cao, Hui Su · 2007
The new H.264/AVC standard can achieve considerably higher encoding efficiency compared to prior video coding standards. In inter-frame coding, not only seven inter modes but also two intra modes are taken into account in order to maintain high encoding efficiency. This paper proposed a novel mathematical model for intra-skip in inter-frame coding, which provides remarkable performance exaltation by cutting down encoding time while accompanying very minor bitrate augment. In addition, this flexible model can be adjusted to various environments on account of adopting different tradeoffs between encoding speed and bitrate. The critical advantage of this novel model is that it can optimize H.264 encoder together with any fast inter methods including inter partition mode decision and motion search algorithms. Also, this model does have potential practical value in the transplantation on DSP if fully developed.
