Color image enhancement is one of the vital emerging techniques in the field of Digital Image Processing (DIP). In this paper, we propose Color Image Enhancement (CIE) utilizing Contrast Limited Adaptive Histogram Equalization (CLAHE), HE, DCT, and so on. The original RGB color image is considered from Computer Vision Group database and is converted to Hue-Saturation-Value (HSV) with homomorphic filter. The processing block which involves local correlation, variance and luminance enhancement are performed on homomorphic filter and the CLAHE is applied on enhanced luminance component output followed by contrast stretching on S component. Finally, the HSV components are converted to RGB and performance parameter of enhancement is obtained. It is seen that the proposed system get better PSNR appeared differently in relation to existing procedures.
