Color image enhancement using daubechies wavelet transform and HIS color model

Abstract

Color image enhancement is very important in digital image processing. In image enhancement image features such as contrast, luminance can be improved at greater extent. In image enhancement the original information does not changes. There are various types of noise present in color images. To enhance the noisy images various image enhancement methods are used and these methods can gives better results than the original corrupted image. In this paper wavelet transform is used for color image enhancement. The proposed method enhances the contrast and luminance as well as removes the noise in the color image. In this proposed method daubechies wavelet transform and HIS color space used.
