Inpainting by Flexible Haar-Wavelet Shrinkage [PDF]
SIAM Journal on Imaging Sciences, 2008 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 for ensuring their convergence are fulfilled ...

MUSCL reconstruction and Haar wavelets [PDF]
Communications in Mathematical Sciences, 2015 MUSCL extensions (Monotone Upstream-centered Schemes for Conservation Laws) of the Godunov numerical scheme for scalar conservation laws are shown to admit a rather simple reformulation when recast in the formalism of the Haar multi-resolution analysis of L2(R).
