Image Denoising New Method Based on Fractional Partial Differential Equation

摘要：

　　Current total variation method excels at denoising and keeping the characteristics of image edges.However,its ability to retain texture details of smoothing region of image is poor.By combining fractional-order differential theory with total variation method,a new image denoising method is proposed.The new method,while effectively inheriting these advantages,uses the fractional-order differential amplitude-frequency and effectively.Simulation results which we have got show that the new method,on the one hand,can better suppress noise,keep the characteristics of image edges,and retain more texture details than integer-order partial differential methods.On the other hand,the method,above mentioned,is more effective and practical on image denoising than results of PSNR.
