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。
We described a multiresolution method based on curvature for constructing a tiling between a pair of planar contours. The method not only inherited the advantages of wavelet multiresolution method [6] , but also might choose effectively the vertex of the contours by characteristics of the curvature. This might approximate adequately the original contours and be benefit to the optimizing processing. Otherwise, this method was operated flexibly and simply, because the curvature was computed by the transform of the B smoothing spline.
