A variational approach to blending based on warping for non-overlapped images

摘要

This paper presents a new model for image blending based on warping. The model is represented by partial differential equations (PDEs) and gives a sequence of images, which has the properties of both blending of image intensities and warping of image shapes. We modified the energy functional in [W.-H. Liao, A. Khuu, M. Bergsneider, L. Vese, S.-C. Huang, S.

The PDEs from the proposed energy functional cover not only overlapped images but also non-overlapped ones.
