基于B样条曲面的图象变形技术

MORPHING METHOD BASED ON B SPLINE SURFACE

Ｍｏｒｐｈｉｎｇ（变形）为图象处理领域比较引人注目的方法之一。本文利用Ｂ样条曲面方法构造Ｍｏｒｐｈｉｎｇ中的映射关系，使得变形过程更容易控制，也更灵活。文中详述了Ｍｏｒｐｈｉｎｇ的一般原理，建立了基于Ｂ样条曲面的映射关系，给出了算法的具体过程，并讨论了实际工作中遇到的一些问题。

Morphing is one of the noticeable methods in image processing. Mapping relation in morphing construction is built through B spline surface so that the morphing process can be controlled with more ease and flexibility. The paper introduces the general principles of morphing process, the method to build the mapping relation based on B spline surface,the algorithm procedures, and some practical problems.
