In this paper, digital image enhancement method is studied and the theory of choosing hard-threshold and soft-threshold in wavelet transform is analyzed, and according to the trait of seismic data, the wavelet threshold is improved. Through the verification of the seismic images in Daqing oil field the new threshold function can effectively remove Gaussian white noise and impulse noise, and the image enhancement effect is remarkable.
