自适应非局部patch正则化图像恢复
Adaptive Nonlocal Patch Regularization for Image Restoration
摘要
Abstract
Nonlocal means exploits the spatial correlation in an image, and preserves the structure information effectively. Combining the nonlocal patch regularization with TV regularization, we propose a nonlocal patch regularized image restoration model.The improved structure tensor matrix can be used to achieve a data-adaptive weigh function, which can then adjust the similarity match process based on the local structure of a pixel. A more simple and effective algorithm -Split Bregman, is used to solve the model iteratively. Compared with other regularization models, our method performs better in improving the quality of restoration image and the efficiency of the algorithm.关键词
