ABSTRACT 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. A new method to enhance the colour image which using the concept of curvelet and multi structure decomposition. The proposed enhancement technique uses DCT (Discrete Curvelet Transform) to decomposed input image into different sub bands. Multi Structure (Morphological) 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 morphological filters. This method will give better qualitative and quantitative results.
