Webdose CT scan imageto improve the contrast. This paper gives a comparative study related to performance of the image fusion techniques. Organization of this paper is as follows; Section 2 ex-plains the image enhancement techniques. The principle of PCA and DWT image fusion techniques are discussed in section 3. In section 4, fusion Webtransform (DWT) is an implementation of the wavelet transform using a discrete set of the wavelet scales and translations obeying some defined rules. In other words, this transform decomposes the image into a mutually orthogonal set of wavelets [17]. In this paper, a comprehensive review of DWT and DCT was studied.
