In this paper, we present a new technique for image inpainting using wavelets. Firstly the damaged area is roughly resorted by the fast marching inpainting method in spatial domain. Then the image is projected onto the wavelet domain, the wavelet coefficient corresponding to the damaged block is revalued based upon the known coefficient of its neighborhood in detail subband, while the wavelet approximation is restored by fast marching inpainting method. An inverse wavelet transform is carried out to get an image in spatial domain. This procedure is repeated in several times and the image is projected onto wavelet domain and spatial domain alternately with being applied suitable constraints in each domain. The method iteratively converges to an image with the damaged area being restored. Our experimental results show that the resulting restored area is homogeneous with its surrounding and the inpainting speed is quite fast.
