Biometric 2D face recognition from camera system placed on a quadrocopter
Mikundová, Lea ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
This Bc. thesis is devoted to face recognization from camera system placed on a quadrocopter. The teoretical part is about the most used methods for detection and face recognition and their comparison. The next part is about motion capturing from quadrocopter. Practical part of thesis is devoted to implementation of algorithms for face detection and recognization by OpenCV library and evaluation of algorithm in respect to distance and angle of quadrocopter due to captured person.

Hybrid 3D Face Recognition
Mráček, Štěpán ; Bours, Patrick (referee) ; Bronstein, Michael (referee) ; Drahanský, Martin (advisor)
Tato disertační práce se zabývá biometrickým rozpoznáváním 3D obličejů. V úvodu práce jsou prezentovány současné metody a techniky pro rozpoznávání. Následně je navržen nový algoritmus, který využívá tzv. multialgoritmickou biometrickou fúzi. Vstupní snímek 3D obličeje je paralelně zpracování dílčími rozpoznávacími podalgoritmy a celkové rozhodnutí o identitě nebo verifikaci identity uživatele je výsledkem sloučení výstupu těchto podalgoritmů. Rozpoznávací algoritmus byl testován na veřejně přístupné databázi 3D obličejů FRGC v 2.0 i vlastních databázich, které byly pořízeny pomocí senzorů Microsoft Kinect a SoftKinetic DS325.

Creating a 3D Face Model Using Kinect Device
Nesvadba, Tomáš ; Malinka, Kamil (referee) ; Mráček, Štěpán (advisor)
The main aim of this bachelor's thesis is to suggest a method for increasing the resolution of 3D face models captured by Kinect. The document describes different methods of capturing 3D models and compares the Kinect sensor with more acurate scanners. The main part of this document is dedicated to statistic model based on the PCA and its usage in the project. The last section of the paper describes testing of various models and discuss the results and another options of aplication.

Human-Computer Interaction Using Kinect
Knot, Stanislav ; Orság, Filip (referee) ; Mráček, Štěpán (advisor)
Abstract This BSc. thesis is concerned about remote control of computer using Kinect device. Sound, depth of image and image capturing is described in thesis. After reading this thesis, reader should have idea of how kinect works, which method it uses and why it uses these. Furthermore, thesis describes design and implementation of alghoritms used in the application.

Biometrical Liveness Detection - Mechanical Characteristics
Zaklová, Kateřina ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
Main focus of this thesis is the detection of liveliness of the finger by the means of mechanical methods. Theoretical part of the thesis describes biometric systems, their reliability metrics, various kinds of sensors and methods of liveness detection. Two methods are covered in detail - liveness detection by odor and liveness detection by temperature. The thesis also illustrates implementation of the application for liveness detection by temperature and evaluates range of experiments carried out during the research.

Automatic Evaluation of Multi-Biometric Systems
Štupák, Richard ; Hrubý, Martin (referee) ; Mráček, Štěpán (advisor)
The objective of the bachelor thesis is evaluation of multi-biometric systems and types of fusion on biometric data. First part explains terms from biometric and multi-biometric systems. Next part describes concept and implementation of individual parts of application. Last part contains experiments with developed application on test data. Purpose of testing was to confirm, that application can find type of fusion with better results.

Map Generator and Path Search in a Map for the Strategy Games
Karásek, Štěpán ; Mráček, Štěpán (referee) ; Orság, Filip (advisor)
This thesis consists of two parts. The first part deals with procedural map generation aiming at terrain generation. For the most part, the bases of terrain generation, usable algorithms and the ways of generating other landscape elements are followed up. A terrain generator using diamond-square algorithm is then implemented and integrated into the existing game engine. The second part of the thesis analyses the pathfinding problem, describes usable algorithms and one of them in detail. Furthemore, the post-processing of the path is being solved and possibilities of hierarchical pathfinding algorithms are presented. Pathfinding using A* algorithm is also implemented and integrated into existing game engine. Finally, functioanality of both the algorithms is demonstrated in an interactive application.

Application Demonstrating Multi-Biometric Fusion
Hanák, Jaroslav ; Hrubý, Martin (referee) ; Mráček, Štěpán (advisor)
This work is focused on biometrics, multi-biometrics, normalization and fusion in multi-biometrics systems and their performance evaluation. It contains a brief introduction to the problem and an overview of the techniques. The aim is to design and then implement an application demonstrating the performance of systems that fall into the category of multi-modal biometric systems. Furthermore, the experiments with the database templates of multi-biometric system and the conclusion summarizes the results.

Software for the Spectroscopy Method LIBS
Vyroubalová, Jana ; Mráček, Štěpán (referee) ; Orság, Filip (advisor)
This thesis discusses creating of software for the LIBS spectroscopy method (for an electronic chamber). In the first part the reader will learn about the LIBS method and about a short description of a workplace, where the project is being created. Then I write about an application design for laboratories, which are going to use this method. Next I describe an implementation of software, where the reader can find some details about used algorithms for autofocus (an evaluation of image sharpness and an iterative determination of the position of the camera). The end of this work is focused on the assessment of GUI and testing the application.
