A Primal– Dual Method for Total- Variation- Based Wavelet Domain Inpainting
ABSTRACT
Loss of information in a wavelet domain can occur
during storage or transmission when the images are
formatted and stored in terms of wavelet coefficients.
This calls for image inpainting in wavelet domains. In
this paper, a variational approach is used to formulate the
reconstruction problem. We propose a simple but very
efficient iterative scheme to calculate an optimal solution
and prove its convergence. Numerical results are
presented to show the performance of the proposed
algorithm.
