Proposed Algorithm For Color Image Enhancement

Abstract

Abstract This paper introduces an algorithm for image enhancement for color images. The proposed algorithm focused to improve the visibility of images , which caused from bad illumination of scenes captured by digital still camera. This algorithm is a combination of two processes which are luminance and contrast enhancement with a dynamic range compression of images. This algorithm, also ensure that remove any discontinuities may happened after processing by using a LPF as a post processing step. A comparison with a Global histogram equalization algorithm also made to verify the activity of the proposed algorithm. The proposed algorithm contains several computation steps, but taking into account the computation speed and best enhancement degree.
