基于仿射变换的运动补偿
摘 要
此文在分析由仿射变换描述的三角形运动补偿基础上，提出了基于重叠区域的三角形运动补偿方法。在引入弹性网概念后，对三角形网格点进行四边形匹配，从而完成了网格点运动矢量的优化精选，提高了运动预测精度。

Motion Compensation Using Affine Transformation
() Abstract
A motion compensation method based on overlapped triangular patches is proposed after analysing the general triangular patch compensation method using affine transformation. With help of the spring net notion,the refining process of motion vector of triangular mesh points is completed by using a quadrilateral matching method,and predictive accuracy may be improved obviously.
