LABORARTORY BRNO
Kříž, Petr ; Joura, Ivo (referee) ; Mikulášek, David (advisor)
Gallery of Architecture, Art and Design. Located at the Brno ring road, at the intersection of Milady Horakove street and Koliště street. The building complets the lines of streets and tapers its accent - the corner. The gallery building is based on the traditional model with a central entrance hall and wings. Central hall situated on the corner, with its variable transparency sends information about what is happening inside and attracts potential gallery visitors. The two side wings are divided on the wing with art exhibition spaces and the technical wing with workshops and supporting functions.

Adaptive frequency filter
Kříž, Petr ; Hájek, Karel (referee) ; Sedláček, Jiří (advisor)
The aim of this work is to design a filter of the type low–pass of order 5th with Butterworth’s approximation in the range of over-tuning 10 – 100 kHz and if it will be possible so! achieve even higher marginal frequencies. To compare two typical representatives of the frequency filters cascading and non-cascading synthesis from the viewpoint the accuracy of an! approximation function, sensitivity to the tolerance values of components, number of the components (mainly OZ) and viability, especially the possibility of electronic over-tuning in selected frequency range. On the basis of these conditions will be chosen one design, which will be realized later. Further it will be necessary to consider the possibilities of electronic over-tuning and to choose for this over-tuning suitable component, to design user management changes of marginal frequency fm by the help of keyboard + LCD and control application on the PC. For this hardware will be programmed appropriate control software. At the end of this work will be constructed appropriate device, which fullfils requirements written above and will be subjected to the laboratory measurements that verify function of this device. The constructional details of the filter are presented in the enclosure at the end of this work. At the CD are available all materials, which were created during the master’s thesis or which are necessarily concerned.

Object tracking in video sequence using the integral histogram
Přibyl, Jakub ; Kříž, Petr (referee) ; Dorazil, Jan (advisor)
This thesis focuses on object tracking in real-time. Tracked object is defined by bounding rectangle. The thesis works on issue of image processing and using histogram for real-time object tracking. The main contribution of the work is the extension of the provided program to track object in real-time with changing bounding rectangle. Size of the rectangle is changing as the object moves closer of further from camera. Furthemore the detection behavior in different scenarios is analyzed. In addition, various weight calculations were tested. The program is written in C++ using OpenCV library.

Measuring positions of objects using a pair of cameras
Sláma, Adam ; Říha, Kamil (referee) ; Kříž, Petr (advisor)
The thesis focuses on acquiring spatial information of a digital image. Simple measuring device consists of two static cameras and of a created software, which is able to find the coordinates of measured object in the sensing area with certain accuracy due to the reference coordinate system. The program was formed in the development environment Microsoft Visual Studio 2015 using package of OpenCV libraries in C++ programming language. The program is based on calibration of image, determination of the global and pixel coordinates and on triangulation method.

Software for Regularity Racing
Kříž, Petr ; Holek, Radovan (referee) ; Štohl, Radek (advisor)
The main goal of this master‘s thesis was to create software solution suitable for measuring and results processing of regularity rally races and to create supplementary web application. The measuring application was created using integrated development environment Microsoft Visual Studio 2015 and c# programming language. For application to work correctly, it was necessary to create a database model, using MySQL relational database management system. The measuring application can work both with local and remote database server. Web application allows user to see various data including results of racing events or tournaments, data are being fetched from the MySQL database. There was an option to explore existing circuit racing software Vola Timing Circuit – Pro for inspiration.

Applications for analysis of tennis player motions
Kříž, Petr ; Beneš, Radek (referee) ; Říha, Kamil (advisor)
This thesis deals with segmentation of tennis player´s body parts for analysis its motion. Testing code was written in C++ with use of OpenCV library. Some image processing techniques such as thresholding, background subtraction or finding the largest contours were implemented. There was used a linear triangulation technique for calculating the 3D coordinates of segmented points.
