Numerical Methods of Image Analysis for Optimal Lens Focusing
Mikuláček, Pavel ; Loučka, Pavel (referee) ; Štarha, Pavel (advisor)
The bachelor thesis deals with determining the optimal focus of the lens. It includes part of the mathematical theory associated with this problem. It explains the mathematical procedure that can be used to decide on the optimal focus of the lens. The result of the work is a single-purpose application that processes images of the Sun and can determine the optimal position of the focusing ring.

Detection of blood elements
Kadlček, Václav ; Kolář, Radim (referee) ; Lamoš, Martin (advisor)
Thesis deals with the detection and subsequent blood elements classification. Blood elements are described mainly in terms of optical features, that is used for digital image processing. Furthermore, available pre-processing theory, image analysis and methods of classifikation are discussed. Acquired knowledges are applied in MATLAB. Image Processing Toolbox is a pillar for that work within this programming environment. The program includes user interface, thus facilitating communication with the program. The program was tested on blood smear images and the results were evaluated.

Visualisation of tissue surface from volume OCT data
Kostiha, Marek ; Lamoš, Martin (referee) ; Čmiel, Vratislav (advisor)
Display surface is almost commonplace for a man. It uses the difference in brightness of individual objects and surface objects. Use in science, however, is considerably more complicated. Modern computer technologies till not its computing power even the human brain. The maximum achievable resolution with the technology but the human eye cannot cope. Although science and other technical fields are significantly burdened by noise that is needed to suppress and some technologies are very challenging, in many ways surpassed human performance and has become indispensable.

Material edge detection system
Hodák, Dominik ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis focuses on the design of a sensor for detecting the edge of materials during rewinding. At the beginning of the thesis, the rewinding line itself is described, there is a description of some sensors suitable for sensing the edge of the material and a short overview of commercial optical barriers. Subsequently, the selection of a suitable sensor, computing platform and communication interface is carried out. Various input filters are then tested and the operation of the finished sensor is described. Next is a description of sensor testing. At the end of the work, several possible improvements to the current sensor are presented.

Detection of Deformable Marker Field
Schery, Miroslav ; Szentandrási, István (referee) ; Herout, Adam (advisor)
This Thesis is focused on study of augmented reality and creation of algorithm for a uniform marker field detector. The marker field is modified to be tolerant to a high degree of deformation. Existing marker types are studied. Important part of the paper is a description of uniform marker field technique, from which a modified assignment is derived. It also describes CUDA architecture on which the first part of the detection algorithm is implemented. Deformation tolerance, detection rate and speed tests are performed on the resulting detector algorithm.
