Traditional Color Image Enhancement Based on Adaptive Filter

Abstract

Color image enhancement is a very important pre-processing stage in face detection and face recognition applications especially when the environment is very dark. In this paper, a color color image enhancement with the adaptive filter and discrete wavelet transform (DWT) is proposed. Discrete wavelet transform is used to improve image enhancement and stationary wavelet transform is used to reduce the halo distortion in gray scale images only and wavelet cannot work in color images. In adaptive filter technique is to reduce halo distortion in color and gray images. The adaptive filter algorithm finds the importance of color information in color image enhancement and utilizes color space conversion to obtain a much better visibility. Experimental results show that adaptive filter to reducing halo, color distortion and produce better visibility compare to DWT.
