In this paper, it was found that the combinations of techniques applied above improved the qualty of the images at $\sigma_1=10$.  As $\sigma_1$ increased, the images appeared to be more distorted, by adding more noise.  As seen in plots, for smaller values of $\sigma_1$, the images are closer to $I$, where increasing $\sigma_1$, images appear closer to $D$
