Yi Zhang · Video Engineering · 2011
Several image enhancement algorithms are introduced.According to the classical histogram equalizing algorithm,a wavelet coefficients equalizing image enhancement algorithm is proposed based on the wavelet transform,and computation steps are given.The proposed algorithm in this paper is compared with the homomorphism filter and the classical histogram equalization.Experimental results indicate that the new algorithm in this paper can enhance image and eliminate noise efficiently.
