Detektor Uniform Marker Fields pro Windows Phone
Mašek, Jiří ; Szentandrási, István (oponent) ; Herout, Adam (vedoucí práce)
Tato práce pojednává o detekci Uniform Marker Fields a umístění kamery v prostoru. Jsou zde popsány vlastní kroky detekce UMF, platforma Windows Phone 8, práce s DirectX a také pojem rozšířená realita. V textu je popsána zároveň implementace a návrh demo aplikace a celá architektura projektu. Výsledkem této práce je aplikace využívající detektor UMF a vykreslující 3D objekt do scény. Na závěr je aplikace otestována a zhodnocena.

Improving Markers for Augmented Reality
Páldy, Alexander ; Juránková, Markéta (oponent) ; Herout, Adam (vedoucí práce)
This thesis briefly describes the modern methods in augmented reality and deals with the synthesis of Uniform Marker Fields. The main purpose of this work is to refine the Uniform Checker-Board Marker Fields. This is achieved by proposing several improvements to the marker field design. The main ones are the use of a color palette, targeting resemblance to an image and changing the shape of the modules. An algorithm was implemented for the generation of such marker fields. As a result, the produced markers are aesthetically appealing, besides they can be reliably detected even when heavily occluded and under terrible lighting conditions.

Eye Tracking During Interaction with a Screen
Pavelková, Alena ; Kajan, Rudolf (oponent) ; Herout, Adam (vedoucí práce)
This work presents system for real-time tracking of computer screen and estimating location of user's gaze on this screen with the use of eye-tracking data from a head-mounted eye-tracker and Uniform Marker Fields. The designed system localizes the computer screen in the frames from eye-tracker's front camera using a fragment of Uniform Marker Field displayed on the screen. The marker is hidden after its successful detection and natural feature points from the camera frame lying on the computer screen or, optionally, from the whole frame, are used for tracking the screen. If the natural features tracking fails, marker is displayed again and the tracking is re-initialized. In order to make the marker as unobtrusive as possible, gaze information is used to display the marker as far from the area of user's visual attention as possible. To evaluate the performance and accuracy of the implemented system and the influence of marker appearing on the screen on user's ability to perform his work, several experiments and user testing were conducted.
