This paper discusses the feature of redundant discrete wavelet transform and proposes an irregular triangular mesh design method in wavelet domain for motion compensation in wavelet video codec.
A motion compensation method based on overlapped triangular patches is proposed after analysing the general triangular patch compensation method using affine transformation.
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。

Meanwhile, the triangular grids are deformed according to the motion of solid bodies with a 'spring' analogy approach.
