| Abstract: | This paper combines the edge enhancing diffusion and the projections onto convex sets algorithm. And a method of projections onto convex sets algorithm based on the edge enhancing diffusion is proposed. This method can reduce the effect of the noise on the image reconstruction,solve the problem of ringing artifact,increase the signal to noise ratio,and improve the super - resolution reconstruction of image,the experiments show that they can combinate well. |

| Keywords: | super - resolution image reconstruction projections onto convex sets edge enhancing diffusion |
