摘要
针对B样条曲线局部修改的问题,提出一种双正交非均匀B样条小波与外部能量约束相结合的算法。与传统能量约束法相比,该算法使曲线除局部修改外整体形变较小,具有一定的保形效果。
For the local shape modification using B-Spline curve, a integrated algorithm of biorthogonal nonuniform B-Spline wavelets and external energy constraints is proposed. The new B-Spline curve with little deformation except for local modification, which is generated by this approach. Compared with the traditional energy constraints method, it is better to preserve shape.
