Image metamorphosis or image morphing

used for creating a smooth transition between two images

is a hotspot in the field of image processing. At present

the morphing processing focuses on two-dimensional images. With more and more images generated from three-dimensional models

extending the morphing techniques to three dimensional models is attracting more attention. In this paper

based on the analyses of feature-based metamorphosis

considering three dimensional data model

we put forward an algorithm on feature-based three dimensional morphing to deal with scatting data. In the algorithm

firstly shifting smooth interpolation is used to simulate the warp

then blending method is used to improve the precision and effect of morphing. The implementation shows that the method is reliable. The method is available for not only three dimensional

but also two dimensional image morphing.
