【摘要】为了实现对视频中运动目标的运动矢量估计，建立了多维矢量矩阵变换域运动估计系统，在变换域对运动视频中运动目标形成的多维能量集中平面进行研究。首先，介绍了多维矢量矩阵理论、变换理论以及运动目标在变换域形成能量集中平面的理论推导；然后，采用平面拟合的方法，求取运动矢量的大小；最后，分析对比了几种方法的效果和迭代速度。实验结果表明：多维矢量矩阵变换域的运动平面拟合方法估计的运动矢量精度达到10－2 pixel，提供了一种变换域运动矢量估计的高精度方法。%To realize the motion vector estimation targeted at moving objects in video, the motion estimation system based on transformation domain of multi-dimensional vector matrix is established.The research is then carried out in transformation domain to study on multi-dimensional energy concentration plane formed by mov-ing objects in moving videos.Firstly, the theory of multi-dimensional vector matrix and transformation are in-troduced.Then the theoretical derivation of energy concentration plane in transformation domain formed by moving objects is presented.The next step is to calculate the motion vector using plane fitting method.Final-ly,the performance and iteration speed among a few methods are analyzed.Experimental results show that the motion vector accuracy
