An Effective method for Satellite Image Enhancement

Abstract

Satellite colour images are being used in many fields of research. One of the major issues of these types of colour images is their poor perception. In this letter a new method to enhance the satellite image which using the concept of wavelet and multi structure decomposition. The proposed enhancement technique uses DWTwith SWT to decomposed input image into different sub bands. Multi Structure decomposition is a Powerful theoretical tool, which is used in nonlinear image analysis .Detecting the positions of the edges through threshold decomposition and these edges are sharpened by using  filter. This method will give
