Abstract

For video communication, Region of Interest (ROI) coding offers an efficient way of improving the quality of videos. In this paper, we propose a novel rate control scheme for Region of Interest coding. We set the area covering people are interested in as the Region of Interest (ROI) to preserve better quality than the background. In addition, we set a coefficient ω to evaluate the significance of ROI, and then use it to calculate the mean absolute distortion (MAD) of the ROI and the background. Finally, the quantization parameter (QP) can be decided by the quadratic model. The difference of QP can be used to distinguish the background and the ROI with the QP which is obtained in advance, so the ROI mask cannot be coded and transmitted. Moreover, through adjusting the coefficient ω to control the degree of the protection of the ROI, our method can protect the ROI effectively and control the difference between the background and the ROI expediently. Experimental results show that the scheme works well in protecting the ROI, the objective quality of the ROI will be improved and the bit-rate can be controlled in a certain range.
