Fast Wavelet Thresholding Algorithms for Face Image Inpainting

Wavelet iteration inpainting has been well known as an important method of image inpainting, which usually requires a lot of iterations. There are some fast algorithm can be used in image inpainting. A Fast Iterative Shrinkage Thresholding Algorithm (FISTA) was introduced to carry out our face image inpainting. Compared with the standard iterative thresholding algorithm, this algorithm is more effective. The numerical experiments show that our algorithms can improve the convergence of the algorithm. In addition, we proposed a new dynamic threshold strategy and got a better restoration quality.
