In this paper, a modified 3D anisotropic diffusion method is proposed to improve the multi-frame image fusion performance. Multi frame image sequence is considered to be composed of aligned and warped images. The goal of this approach is to obtain a restored image from the aligned and warped image sequence, where alignment error and Gaussian noise are reduced. The proposed method consists of medium band stack filter and tree-structured 3D diffusion filter.
