Survey on Multimodal Medical Image Fusion Techniques

An Image fusion is the development of amalgamating two or more image of common characteristic to form a single image which acquires all the essential features of original image. Nowadays lots of work is going to be done on the field of image fusion and also used in various application such as medical imaging and multi spectra sensor image fusing etc. For fusing the image various techniques has been proposed by different author such as wavelet transform, IHS and PCA based methods etc.The key objective of vision fusion would be to merging information from multiple images of exactly the same view in order to deliver only the useful information. This paper has centred on the many image fusion techniques. The review has shown that the still much research is needed to improve the image fusion technique further.
