Survey on Different Types of Images and Image Fusion Techniques

Abstract

Image fusion is an image processing technique to combine two or more images of same scene with little dissimilarity to obtain much relevant image than the input images. Image fusion is a study which has undergone  many evolutions since time; as such each case study contains different set of inputs and thus require different approaches of algorithm. This paper provides a literature survey on different types of images and image fusion process applied on them, along with a survey on types of color images taken for registration and their image fusion techniques. Widely accepted methods to perform image fusion are simple image fusion, pyramid decomposition based fusion, discrete transform based fusion. They are applied based on different input images and required characteristics in the output image.
