Analiza metodelor de restaurare a imaginilor distorsionate, efectuate cu ajutorul sistemelor opto-electronice

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.
