The process of enhancement consists of three component elements: de-noising based on wavelet, image fusion, contrast enhancement based on multi-scale wavelet transform. Because the wavelet transform has character of multi-scale, multi-resolution analysis and time-domain localize, image enhancement methods based on wavelet transform can improve conventional methods of image enhancement. This paper...
