| 摘 要： | 提出了一种对立体视频序列进行视差估计的新方法,利用立体视频序列前后帧之间的运动信息,来提高视差估计的精度.为了得到精确的视差图,必须找出遮挡区域并对遮挡区域的视差进行补偿.在立体视频序列中,由于前景或背景对象的运动,当前帧中的遮挡区域在前后几帧中的运动对应区域可能不是遮挡区域,因此可以利用这些对应区域的视差值来补偿遮挡区域的视差.实验结果表明本方法能对大部分遮挡区域的视差进行补偿,得到更精确的视差图.

| Abstract: | A new method is presented for disparity estimation of stereoscopic video sequences. To achieve a precise disparity map, we must find out the occluded areas and compensate the disparity of these occluded areas. To some occluded areas in the present frame, their correspondent areas in the next or last frames may be not occluded areas because of the motion of foreground or background objects. Thus we can use the disparity of these correspondent areas to compensate the disparity of the occluded areas. Experimental results indicate this method performs well to the majority of the occluded areas and achieves more precise disparity maps. |
