Inpainting by Flexible Haar-Wavelet Shrinkage

We present novel wavelet-based inpainting algorithms. Applying ideas from anisotropic regularization and diffusion our models can better handle degraded pixels at edges. We interpret our algorithms within the framework of forward-backward splitting methods in convex analysis and prove that the conditions to ensure their convergence are fulfilled. Numerical examples illustrate the good performance of our algorithms.
