Paper Abstract

In this paper, we propose a GA (Genetic Algorithm) image restoration method which has PSF (Point Spread Function) parameters as genes. The proposed technique restores an original image from its observation image which has been blurred partially by defocusing of a lens system. Though the degraded model of an image is a Gaussian function type, the value of distribution of the parameter which is assumed to be space variant is exactly unknown at each place. For this case, the evaluation function based on 'Regularization Theory' was proposed and some simulation experiments were performed, so that the validity has been shown on this study.
