Blind restoration of blurred images using local patches

摘要

In this paper, we propose a blind method that rapidly restores blurred images using local patches. In this method, a portion of the blurred image is used for PSF (point spread function) estimation. In addition, we propose an automatic PSF size calculation algorithm that generates an autocorrelation map (auto map). Experimental results show that our proposed method generates accurate deblurred images, and processing time is significantly lower than that of the conventional deblurring method.
