摘 要 :本文阐述了一种基于曲率的多分辨率缝补方法。该方法不仅继承了小波多分辨率缝补方法[6] 的优点,而且,利用轮廓曲率的特性,可以更有效地选取轮廓的顶点,使得对原始轮廓的近似更合理,此特性对于优化过程也是有直接帮助的。另外,由于采用了B样条平滑变换计算曲率,使得本方法变得更为简单、更便于操作。

ABSTRACT :We described a multiresolutionmethod based on curvature for constructing a tiling between a pair of planar contours. Themethod not only inherited the advantages of wavelet multiresolution method[6] ......
