Fast image enhancement in compressed wavelet domain ?
We propose an efficient and flexible image enhancement framework. Brightness, contrast, sharpness, noisiness, and color consistency are considered for enhancement. Wavelet properties enable both global and local enhancement. The framework achieves computationally efficient for best wavelet encoded images since enhancement is performed in the wavelet domain. The experiments show that the proposed method achieves both visually and numerically good results to the existing approaches.
