| 摘 要： | 提出用于电子稳像的一种改进的灰度码位平面运动估计算法.该算法首先提取视频中当前帧和参考帧的相邻2层位平面,并进行比特变换,然后对其进行子图像运动估计,从而得到当前帧相对于参考帧的运动矢量,进而进行运动补偿,实现视频稳定.实验结果表明,该算法能在减小计算复杂度的同时提高稳像精度,实际应用效果较好.

| Abstract: | An improved algorithm for gray bit-plane motion estimation for image stabilization system is developed.Firstly,this method extracts and bit-switches the adjacent bit-plane images which are from the present image and the reference image,then estimates the motion of the sub-image,and obtains the motion vectors of the present image relative to the reference image,which carry out motion compensation and realize video stability.Experimental results show that this algorithm can reduce the computational complexity... |
