Review on improved image fusion approach

Image fusion is the process of blending all the essential information from multiple images, and their incorporation into fewer images, generally a single one. The single image which is accessed by image fusion gives more information and is rigorous than any single source image. This image encompass all the important information. The image fusion is not only purposed to diminish the amount of data but also to frame images that are more convenient and pertinent for the machine and human approach. Certain situations in image processing need both high spectral and high dimensional information in a single image, which is important in remote sensing. Image fusion techniques involve filtering, enhancing and decomposing the images for better results. This paper emphases on the imperative and efficient approaches for image fusion.
