In our shadow removal applications we estimate the local structure via a modified tensor voting approach (Moreno, 2012) and use this information within an anisotropic diffusion inpainting that resembles edge-enhancing anisotropic diffusion inpainting (Weickert, 2006, Gali'c, 2008). For a regular image domain Ω ⊂ R 2 and a stopping time T > 0, given a degraded image f ∈ L ∞ (Ω; R) and two smoothing parameters ρ, σ > 0, the anisotropic diffusion model in [37] looks for a solution u in a suitable function space satisfying the following initial value problem: In this section we present several numerical examples showing the application of the isotropic and anisotropic osmosis model to solve the shadow removal problem in synthetic and real-world images.	./cache/cord-102233-50ldj8j7.txt	./txt/cord-102233-50ldj8j7.txt
