Image denoising numerical methods based on space fractional Partial Differential Equations is an important direction of image denoising field, and its study of numerical methods has important theoretical significance and practical value. This paper constructs implicit difference scheme for solving the space fractional partial differential equation. Through theoretical analysis and numer-ical experiments, we found that implicit difference scheme for solving space fractional partial dif-ferential equations is feasible, it can ensure good denoising effect.
