Scientific activities and field of expertise

Optics, Image Processing and Inverse Problem in problems of image restoration, image recognition and the assessment of information quality of optical systems.

The following results were achieved:
  • The new linear method of orthogonalisation of image basis functions for the regularization of the signal restoration for solving of the Fredholm integral equation of the first kind is developed;
  • Methods minimum square error (MSE), selection of sampling points and statistical properties of a noise and an object optimization;
  • Nonlinear reccurent method of the object restoration from images gathered by linear system;
  • The statistic assessment of the object restoration error for irregular sampling points of an image;
  • New method of image restoration from several images, gathered combined systems is developed;
  • Method of image correction for the moving object;
  • Assessment of information properties of optical systems based on MSE of restoration;

  • List of publication consists of more than 70 publications, which include papers in referred journals, article in the book, patent
    and papers in proceedings of conferences.
