The Study Of Difference Schemes In Image Denoising Based On Partial Differential Equation

Image denoising has been the important research contents of image academic and engineering, except the space domain method we often use the partial differential equation has been widely used. This paper applies partial differential equation(PDE) theory to improve the solutions of difference scheme in the process of solving equations.We use alternating direction implicit schemes to disperse PDE,and compare the consequence with the result of common explicit scheme. Getting through experimental result,we can not only get better effect,but also enhance the arithmetic speed making use of the P-M model.
