The comparison of edge detectors
Dula, Marek ; Loučka, Pavel (referee) ; Procházková, Jana (advisor)
In this bachelor thesis we focus on the comparison of different methods for finding edges and filtering noise in the image. In the introduction, we focus on basic concepts related to the issue. Subsequently, we describe the individual methods of edge detection and noise filtering in the picture. The next part contains software processing of individual methods in Matlab software. Finally, we compare the individual noise filters and edge detectors.

Identification and visualization of the coordinate system of the cornea during lens implantation
Hudec, Jiří ; Odstrčilík, Jan (referee) ; Harabiš, Vratislav (advisor)
The dissertation describes the method of inserting polar-axis system into the video recording of cataract operation at the Geminy Eye Surgery, Zlin. At the theoretical part, it discusses requirements for inserting the polar-axis system including elimination of eye rotary movements captured by slit lamp. Then the emphasis is also on the speed of data processing. The practical part of the dissertation, focuses on the creating the method for detection of centers at the slit lamp picture, as well as video sequence and a method that eliminates potential eye rotation. For designing the program solution, following methods were used: Otsu method, Hough transformation method, method of two vertical projections, and crosscorrelation method. In total, the program solution was tested and analyzed in Matlab program on anonymous data set of 22 eyes.
