I2C Bus to RS232 Bus Convertor
Votava, Martin ; Marvan, Aleš (referee) ; Orság, Filip (advisor)
The main goal of this Bachelor's thesis is to create I2C bus to RS232 bus convertor. Using I2C bus the convertor drives 8bit I/O expander. In theoretical part buses I2C and RS232 are described along with PCF8574. There is also mentioned selection appropriate microcontroler and design of comunication protocol. Practical part is dedicated to creating control program for microcontroler, appropriate comunication protocol processing and convertor testing. There are also described some auxiliary products and program testing.

Real Time Suppression of Atmospheric Turbulence
Macků, Jiří ; Orság, Filip (referee) ; Marvan, Aleš (advisor)
This paper deals with removing undesirable image deformations caused by turbulences of Earth's atmosphere. The goal is to design and implement algorithm for suppression of atmosphere turbulence in video sequences to use in long-distance camera monitoring system. This paper also focuses on optimization of existing algorithms for running in real-time. Algorithm will be implemented in C++ programming language with use of library for computer vision OpenCV.

Robot for MiniSumo
Marvan, Aleš ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This thesis deals with the subject of a mobile robot design for an international competition Minisumo. The work includes both a theoretical presentation of the robot design as well as the documentation of its realization. The development process starts with a creation of a theoretical basis, which is functioning as a source of information for the consecutive design of the mechanics, electronics and final production of the robot. The work also includes the development of control software necessary for the correct operation of the robot.

Analysis of Parking Availability
Stránský, Václav ; Rozman, Jaroslav (referee) ; Marvan, Aleš (advisor)
This thesis deals with an analysis of parking availability. The task is to determine the occupancy of predefined parking places in the sequence of color images acquired by a fixed camera. The thesis describes the design, implementation, and testing of three utilized methods for car detection, i.e. background modelling, edge detection, and histogram comparison. These methods are combined in order to obtain a more robust and accurate solution. The proposed system has been successfully tested on several real scenarios.

Shooting Range Simulator with Image Processing
Csóka, Pavel ; Drahanský, Martin (referee) ; Marvan, Aleš (advisor)
This thesis is aiming on design and implementation of Shooting range simulator with image processing. It is based on detection of a laser spot on the projection plane where the target is displayed (dataprojector or LCD) by using camera which captures image of this plane. It designs and implements the detection software using C++ language and OpenCV computer vision library and describes gun modification, which consists of design and creation of control unit for this gun and fitting it in. Control unit is based on STM32 microcontroller device, its firmware implementation is done using C language. It describes approaches in computer vision applications used in this thesis and main features of used microcontroller. Practical tests are made to analyze system's function. In the final chapter is the summarization of this thesis and suggestions to further development and improvement of this system.

Universal Robotic Platform
Marek, Martin ; Kunovský, Jiří (referee) ; Marvan, Aleš (advisor)
This work deals with the proposal of the universal robotic platform. The paper descibes a robotic competition for which is posible to use this platform. There is a list of basic sensors that are suitable for small robot competition. Of course there is a short description for each sensor. In the chapter of the draft prototype are described types of chasis. There is an explanation of use of the differential gear for this platform. The text also describes the development of the prototypes platfom and used data bus for comunication between the periferies and the MCU.

Design of a Body and Sensor System of a Robot
Marvan, Aleš ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis deals with a problematic of mobile robot design. There is proposed a design and realization of a mobile robot intended for an international competition - Minisumo. The first step in the development process is collecting of information, which helps us to find the most suitable elements. The next step is choosing of the individual elements fulfilling the design requirements according to their specification.

Porting and Optimization Algorithms for Detecting Finger Veins on DSP Blackfin
Trhoň, Adam ; Drahanský, Martin (referee) ; Marvan, Aleš (advisor)
This thesis discuss optimizations of algorithms for finger vein map extraction from finger image taken in NIR spectrum. The algorithm is also ported on development kit with DSP Blackfin. For optimization the median filtering was mainly considered (resulting in histogram-based median filter) and the amount of memory used during extraction (resulting in semi-parallel pipeline of image filters). Simple hardware abstraction layer is also implemented.
