We propose a new model for image restoration and decomposition, based on the total variation minimization of Rudin-Osher-Fatemi (1992), and on some new techniques by Y. Meyer (2002) for oscillatory functions. An initial image f is decomposed into a cartoon part u and a texture or noise part v. The u component is modeled by a function of bounded variation, while the v component by an oscillatory function, with bounded H-1 norm. After some transformation, the resulting PDE is of fourth order. The proposed model continues the ideas and techniques previously introduced by the authors in L Vese et al., (2002). Image decomposition and denoising numerical results will be shown by the proposed new fourth order nonlinear partial differential equation.
