英文摘要	Region of interest (ROI) has been widely used in the extensive applications, such as video conferencing, video surveillance, videophone etc. In this paper, an optimal bit allocation scheme between ROI and non-ROI area is proposed, which aims to improve the visual quality of ROI while guarantee the overall visual quality (OVQ) of the video is also optimal. In the proposed scheme, the visual quality of a certain area, including ROI and non-ROI, is predicted by a visual quality model, and the overall visual quality is modeled by the visual quality difference between ROI and non-ROI. Based on the proposed visual quality models, the optimal bit allocation is achieved, and experimental results show that the proposed scheme can effectively improve the overall visual quality of the video.; EI; 0
