Image Fusion Survey: A Comprehensive and Detailed Analysis of Image Fusion Techniques

Abstract

Image fusion is very trending area of research in the field of image processing. It has vast range of applications in miscellaneous fields like surveillance, diagnosis, and photography. In this survey paper, all the methodologies have been discussed and various approaches are given to overcome the shortcomings of sundry problems. Detailed analysis is carried out in this paper. Many efforts have been made to find out the challenges and also the achievements done so far. We undergo various research papers and tried to cover every aspect relating image fusion. Multi-scale transform image fusion methods have been discussed on the basis of their domain, i.e., in spatial and frequency domain. First, image fusion is explained in details with its major applications as well as techniques entangled. Second, comparison of various fusion methods is done in tabulation. Finally, concluded with the current insightful discussions of image fusion and future aspects. This survey will be used as a reference for image fusion related domain.
