Wavelet based Image Enhancement using Fusion

Description

Image fusion is an image enhancement approach for increasing the visual perception from two or more image into a single image. Each image is obtained from different object in focus. This process is now broadly used in various application of image processing such as medical imaging such as MRI, CT [18] and PET, remote sensing, satellite imaging, in design of intelligent robot etc. In this paper we have gone through the literature work done by the various researchers to obtain high quality improved image by combining important and desirable features from two or more images into a single image. Different image fusion rules, like maximum selection scheme, weighted average scheme and window based verification scheme are discussed. We also discuss about the image fusion techniques using DWT. Distinct blurred images are fused using DWT, SWT and using local correlation and their results are compared. The role of fusion in image enhancement is also taken into consideration. The results of different fusion technique are also compared, which are furnished in pictures and tables.
