Superresolution of Images Using Area Preserving Geometric Evolution Laws
Figure 2
Superresolution of text (a) bicubic interpolation, (b) Willmore flow, (c) mean curvature flow, (d) surfaces diffusion, (e) zoom from left to right: bicubic interpolation, Willmore flowm mean curvature flow, and surface diffusion. The evolution results are shown after 10 time steps. The number of time steps used results from our individual taste for the best result.
