摘要：Image denoising is a basic problem in image processing, fourth order partial differential equation model is an image denoising method proposed for maintaining the balance of denoising and edge keeping. But when the image is severely contaminated, the denoising effect is not ideal, it may fuzzes the boundary at the same time, this paper puts forward an improved fourth order partial differential equation model, in order to overcome the contradiction between denoising and edge keeping, better denoising effect is obtained, and through the numerical simulation the results show that the method has good stability and practical value
