AB - <p style="text-align: justify;">In this paper, we introduce a novel hybrid variational model which generalizes
the classical total variation method and the wavelet shrinkage method. An
alternating minimization direction algorithm is then employed. We also prove that it
converges strongly to the minimizer of the proposed hybrid model. Finally, some numerical
examples illustrate clearly that the new model outperforms the standard total
variation method and wavelet shrinkage method as it recovers better image details
and avoids the Gibbs oscillations.</p>
