Investigation of Shift Dependency Effects on Multiresolution-Based Image Fusion Performance

Image fusion techniques using multiresolution decomposition have become a hot research area due to the fact that it is suitable for multi-scale properties of the human vision system. According to subsampling methods, multiresolution decompositions can be divided into redundant and non-redundant which corresponds to different shift dependency such as shift-variant or shift-invariant. However, there have been comparatively few studies that have focused on its effects on the fusion performance. This paper investig
