An improved method for deconvolving a positive image

摘要

This paper describes an improved technique for enforcing positivity in deconvolution applications. An accelerated quadratic programming approach is applied and shown to be an improvement to a method proposed by Nakamura et al. [J. Opt. Soc. Am. A 5 (1988) 554]. The resulting algorithm produces a monotonically decreasing error function and guaranteed convergence. The performance of the algorithm is tested on computer simulated images.
