Blind deconvolution deep learning
WebApr 6, 2024 · Blind image deblurring is a challenging problem, which aims to estimate the blur kernel and recover the clear image from the given blurry image. A large number of image priors have been proposed to tackle this problem. Inspired by the fact that the blurring operation increases the ratio of dark channel to local maximum gradient, a weighted dark … WebContext. Observations from ground-based telescopes are severely perturbed by the presence of the Earth's atmosphere. The use of adaptive optics techniques has allowed us to partly overcome this limitation. However, image-selection or post-facto image-reconstruction methods applied to bursts of short-exposure images are routinely needed …

WebBlind image deblurring, one of the main problems in image restoration, is a challenging, ill-posed problem. Hence, it is important to design a prior to solve it. Recently, deep image … WebBlanc et al.(2003) consider the marginal deconvolution in the same problem. Along this line,Thelen et al.(1999) solve the blind deconvolution problem by assuming a multivariate Gaussian prior for the wavefront parameters. The emergence of deep learning has revolutionized the field of image processing. In particular, methods have been proposed
