Homorphic fltering algorithm based on FFT and hmomorphic fltering algorithm based on WT is studies. Through the application of Matlab to simulate these image enhancement algorithms,the simulation experiment indicates that the FFT-based homomorphic filtering,image contrast increased overall,but not performing local contrast enhancement; while WT-based homomorphic filtering algorithm,the effective elimination of the impact of uneven illumination,especially near the edge of the image significantly enhance local contrast.
