A general framework for multiresolution image fusion: from pixels to regions

摘要: This paper presents an overview on image fusion techniques using multiresolution decompositions. The aim is two-fold:($ i $) to reframe the multiresolution-based fusion methodology into a common formalism and, within this framework,($ ii $) to develop a new region-based approach which combines aspects of both object and pixel-level fusion. To this end, we first present a general framework which encompasses most of the existing multiresolution-based fusion schemes and provides freedom to create new ones. Then, we …
