- W2783402350 abstract "It has been shown that the quality of multimedia video and the need of real time video transmission become widely increased in these days and high efficiency video coding (HEVC) becomes the newest standard. Based on the theory of ratedistortion coding, the R-X model can describe the rate-distortion relationship more accurately in comparison with the existing traditional R-Q model. With the development of screen content coding, this paper proposes a new adaptive intra frame complexity measure method based on two complexity measure methods with a relative coefficient for intra bit rate control, respectively are the gradient based complexity measure and edge based complexity measure. Then the paper proposes an improved rate control method for the intra-frame rate control, which merges the adaptive intra frame complexity measure with R-X model based on HEVC. Along with this new adaptive rate control approach, it will show improved accuracy in rate control and enhanced performance in video coding which means better video quality. The proposed scheme can reduce the frame bit mismatch ratio by 2.8175% on average and the better B-D Rate which is 0.94% on average. Experimental results verify the effectiveness of the proposed intra frame complexity method based on X-domain rate control algorithm." @default.
