Robotic manipulator for ionizing radiation sample measurement
Míček, Vojtěch ; Štohl, Radek (referee) ; Petyovský, Petr (advisor)
This bachelor thesis is interested in designing of robot manipulator for measurement of active samples for ionizing radiation laboratory of Department of Electrical Power Engineering VUT Brno. The goal is to create robotic manipulator which will be easy to manufacture, easy to control, absolutely reliable, cheap and accurate enough. So, it will radically reduce time consumption of measurement of neutron field. Construction is based on FM-SYSTEME aluminium structural framing, manipulator is controlled by Arduino Nano and movement is provided by stepper motor Microcon SX23-1414 and drver TMC2208.

HDR image processing tool
Kocich, Petr ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
First part describe terms HDR, image processing and some basic terms of photography. There is describe requirements for corect capture high dynamic range scene through the use of colection of photos with same scene but with diferent exposure value. Next thing is describnig principles for connect these photos to one photo with high dynamic range. Tone mapping methods describes compression of high dynamic range to dynamic range of standard screens. Some commercial program for HDR making is describe here. Main algoritmus show possibility how display high dynamic range scene through the use of kernel of usefull areas.

Microsolder controlled by microprocessor
Stavělík, Jiří ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This thesis describes circuit design and realization of the power and control system, which can hold constant temperature of solder tip. Control system is based on microcontroller Atmega328 of company Atmel, part of the work is the implementation and debugging control software. This solution allows to enter temperature by rotary encoder and to show the real temperature on LCD displey. This hardware also detects disconnection of solder tip, acoustic signals when the required temperature is reached and it holds last set temperature.

3D data presentation
Matyskiewicz, Jiří ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
Thesis deals with manipulation, archiving and viewing of 3D data. Theoretic part contains basic introduction to the field. Practical part of the thesis is design and implementation of the library for viewing 3D data and viewer / editor using this library. Library is written in c++ computer language and it’s intended to be used as a dynamic linked library, which functionality can be easily enhanced with additional plug-in modules without need to modify the source code of the library. Actual viewing is not tied to any specific type of graphical API, library can be extended with plug-in for rendering using any software or hardware. Part of the implementation is plug-in for rendering 3D data using OpenGL interface.

Hand gesticulation recognition in image
Mráz, Stanislav ; Petyovský, Petr (referee) ; Horák, Karel (advisor)
This master’s thesis is dealing with recognition of an easy static gestures in order to computer controlling. First part of this work is attended to the theoretical review of methods used to hand segmentation from the image. Next methods for hang gesture classification are described. The second part of this work is devoted to choice of suitable method for hand segmentation based on skin color and movement. Methods for hand gesture classification are described in next part. Last part of this work is devoted to description of proposed system.

Measuring of Vehicle Instant Velocity
Štencel, Jakub ; Petyovský, Petr (referee) ; Horák, Karel (advisor)
The theoretical part of this paper summarizes the methods for motion analysis in an image. Inspected in detail are the methods used for motion detection in the image sequences. The practical part is focused on finding the significant points in the image (the targeting reticles on the body of the vehicle) which are then used to calculate the speed of the vehicle.
