Superresolution of Images Using Area Preserving Geometric Evolution Laws
Figure 3
“Lena’’ image from left to right: (a) bicubic interpolation, (b) Willmore flow, (c) mean curvature flow, (d) surfaces diffusion. The evolution results are shown after 20 time steps in the case of Willmore flow and surface diffusion and 8 time steps for mean curvature flow. The number of time steps used results from our individual taste for the best result.
