Blind deconvolution by means of the Richardson-Lucy algorithm
A blind deconvolution algorithm based on the Richardson–Lucy deconvolution algorithm is presented. Its performance in the presence of noise is found to be superior to that of other blind deconvolution algorithms. Results are presented and compared with results obtained from implementation of a Weiner filter blind deconvolution algorithm. The algorithm is developed further to incorporate functio...
متن کاملBlind Deconvolution and Deblurring in Image Analysis
Blind deconvolution problems arise in image analysis when both the extent of image blur, and the true image, are unknown. If a model is available for at least one of these quantities then, in theory, the problem is solvable. It is generally not solvable if neither the image nor the point-spread function, which controls the extent of blur, is known parametrically. In this paper we develop method...
متن کاملDeconvolution of Sub-pixeled Richardson-Lucy Algorithm
We introduce a Modiied Richardson-Lucy Algorithm for reducing data from the Subaru AO system. This new algorithm applies Magain's correct sampling approach to the Classical Richardson-Lucy algorithm. We have evaluated its performance for astronomical usage, appearance of the object and photometric accuracy, and compared our results to those obtained with a Classical Richardson-Lucy Algorithm.
متن کاملIterative 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 کاملA Deconvolution Error Avoidance Technique in Richardson- Lucy Method
A deconvolution error avoidance technique in Richardson-Lucy deconvolution (RLdeconv) is proposed, which is used for inversely analysing the SRAM margin variations caused by the Random Telegraph Noise (RTN). The proposed technique reduces the phase difference between the deconvoluted RTN distribution and feedback-gain in the maximum likelihood (MLE) gradient iteration cycles. This avoids an unw...
