Anisotropic diffusion filtering can preserve the border structures of seismic texture images efficiently, which always applied in image enhancing. Based on the analyis of Curvelet thresholds, an new effective method was presented in this paper which combined the advantages of both curvelet transform and anisotropic diffusion. The new method can remove random noise and preserve edge structures of seismic events at the same time, which was certified by the test of theoretical and actual seismic data. Advantages on improving signal to noise ratio and edge preserving were analyzed through six kinds of quantitative evaluation indexs.
