【Abstract】 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.更多还原
