Iterative methods of Richardson-Lucy-type for image deblurring
Image deconvolution problems with a symmetric point-spread function arise in many areas of science and engineering. These problems often are solved by the Richardson-Lucy method, a nonlinear iterative method. We first show a convergence result for the Richardson-Lucy method. The proof sheds light on why the method may converge slowly. Subsequently, we describe an iterative active set method tha...
متن کاملBlock-iterative Richardson-Lucy methods for image deblurring
Image Deblurring Nam-Yong Lee ∗ Department of Applied Mathematics, Institute of Basic Sciences, Inje University, Gimhae, Gyeongnam 621-749, Korea Abstract In this paper, we extend the Richardson–Lucy (RL) method to block iterative versions, separated BI-RL and interlaced BI-RL, for image deblurring applications. We propose combining algorithms for separated BI-RL to form block artifact-free out...
متن کاملAn Adaptively Accelerated Lucy-Richardson Method for Image Deblurring
We present an adaptively accelerated Lucy-Richardson (AALR) method for the restoration of an image from its blurred and noisy version. The conventional Lucy-Richardson (LR) method is nonlinear and therefore its convergence is very slow. We present a novel method to accelerate the existing LR method by using an exponent on the correction ratio of LR. This exponent is computed adaptively in each ...
متن کاملVector Extrapolation-Based Acceleration of Regularized Richardson Lucy Image Deblurring
Confocal fluorescence microscopy has become an important tool in biological and medical sciences for imaging thin specimen, even living ones. Due to out-of-focus blurring and noise the acquired images are degraded and thus it is necessary to restore them. One of the most popular methods is an iterative Richardson-Lucy algorithm with total variation regularization. This algorithm while improving...
متن کاملIterative Methods for Image Deblurring
This tutorial paper discusses the use of iterative restoration algorithms for the removal of linear blurs from photographic Images which may also be assumed to be degraded by pointwise nonlineariries such as film saturation and additive noise. lterative algorithms are particularly attractive for this application because they allow for the incorporation of various types of prior knowledge about ...
