| Abstract: | The dual-tree complex wavelet transform is a useful tool in signal and image processing. In this paper, we propose a dual-tree
complex wavelet transform (ℂWT) based algorithm for image inpainting problem. Our approach is based on Cai, Chan, Shen and
Shen’s framelet-based algorithm. The complex wavelet transform outperforms the standard real wavelet transform in the sense
of shift-invariance, directionality and anti-aliasing. Numerical results illustrate the good performance of our algorithm. |
