Adaptive Detail Enhancement Algorithm of Color Image Based on Wavelet Transform
A novel adaptive detail enhancement algorithm based on wavelet transform is proposed aiming at color image. Firstly right color model is chosen, and then luminance component of the image is being implemented wavelet transform while chroma components are hold on. Finally detail wavelet coefficients are adjusted adaptively considering contrast of approximate image on every level. Then approximate coefficients are increased properly to boost average luminance of color image. During the image processing extra adjustment parameters need not to be specified. Simulations confirm that the algorithm not only preserves the brighter details but also improves the darker details in images while color distortion is not appeared.
