Analiza metodelor de restaurare a imaginilor distorsionate, efectuate cu ajutorul sistemelor optoelectronice

Abstract

In the work were shown the causes of distortions of images such as blurring, defocusing and noise. The known methods for restoring the distorted image: inverse filtering, filtering by minimizing the standard deviation (Wiener filter) filtration method to minimize the smoothing functional with a link (Tikhonov regularization), a non-linear iterative algorithm Lucy-Richardson (maximum likelihood method) were considered. A comparison of these algorithms identified their strengths and weaknesses in relation to recovery was held on. The directions for further research were determined.
