摘　　要：在形态运算的基础上提出了一种广义形态变换方法 .首先将被渐变物体进行凸剖分 ,对得到的子凸集进行匹配映射后再进行形态和插值 ,然后再将各变换结果合并即得到最终结果 .实验证明 ,此广义形态变换方法可以很好地解决非同构物体和凹体间的渐变 ,效果自然、质量好、速度快、自动化程度高 .可用于非刚体运动描述及二维动画关键帧的内插等领域 .A novel generalized morphologic interpolation theory for describing concave objects or non homotopic metamorphosis is proposed. By decomposing two objects into sets of individual convex sub objects respectively, constructing the mapping between two sets is constructed, and the morphological addition of mapping sets is calculated. This method can solve the metamorphosis problems of two non homotopic objects(including concave objects and holey objects). The experiments show that this method can get natural high quality metamorphosis results by simple computation. This method can be used in the field of non rigid object motion and computer animation.
