Digital image

Lecturer:

Ondřej Drbohlav

Tutor:

Ondřej Drbohlav

Supervisor:

Department of Cybernetics

Synopsis:

First, the subject teaches how to process two-dimensional image as a signal without interpretation. Image acquisition, linear and nonlinear preprocessing methods and image compression will be studied. Second, image segmentation and registration methods will be taught. Studied topics will be practised on practical examples in order to obtain also practical skills.
