Rekonstrukce 3D objektu z obrazových dat
Cír, Filip ; Kršek, Přemysl (oponent) ; Španěl, Michal (vedoucí práce)
Tato práce se zabývá 3D rekonstrukcí z obrazových dat. Jsou popsány možnosti a přístupy k optickému skenování. Ruční optický 3D skener se skládá z kamery a zdroje čárového laseru, který je vzhledem ke kameře upevněn pod určitým úhlem. Je navržena vhodná podložka se značkami a je popsán algoritmus pro jejich real-time detekci. Po detekci značek lze vypočítat pozici a orientaci kamery. Na závěr je popsána detekce laseru a postup při výpočtu bodů na povrchu objektu pomocí triangulace.

Creation of Database and Classification of Diatoms
Svoboda, Jan ; Nötzel, Ralf (oponent) ; Drahanský, Martin (vedoucí práce)
The final application works with the designed database, containing images of the individual diatoms and the information about them stored in XML file. The basic operations over this database are secured, such as adding, modification, deleting and searching. The searching can be performed in three ways, by means of textual inputs, image inputs or their combination. The algorithm of searching by means of image inputs tries to find the most similar candidates within the database, considering the shape and thickness of a diatom shell and the internal structure of a diatom itself. This search is specified mostly by the quality of obtained pictures or images of the diatoms compared. The program contains a clear and intuitive graphic interface that conveniently enables us to browse the current database and to perform operations over it, contains set up filters for better recognition.

Application for Implementation of Digital Images Morphological Transformations
Kečkéš, Miroslav ; Beneš, Radek (oponent) ; Říha, Kamil (vedoucí práce)
This thesis deals with the implementation of basic morphological operations on binary and gray-tone digital images. Partly devoted to filling in areas and thresholding, as the basic method of segmentation. The thesis is divided into two parts. The first part deals with the theoretical analysis of the various morphological operations and is divided into four chapters. The first chapter deals with basic concepts used in morphology and basic operations on binary and gray-tone images. The second chapter deals with the segmentation threshold, which is relevant for pre-treatment image. The third chapter describe the basic methods for filling areas. The last chapter deals with various functions necessary to implement the various operations in the sample application. The second part contains the actual implementation of applications.
