A variational model for image decomposition based on total variation and
H
-1 norm is proposed
whose start is different from the OSV model.By the propertied of OSV model
the nonlinear partial differential equation and the associated iterative algorithm based on wavelet method are introduced.And the proof of the existence of minimizer for the variational model is given.Numerical results of image decomposition and denoising show that this model is feasible.
