Analysis of Transactions in a Real Estate Market Segment - Microlocation of Brno
Talaš, Libor ; Fráňa, Tomáš (referee) ; Cupal, Martin (advisor)
The diploma thesis deals with the analysis of real estate transactions in a selected micro-region. The selected region is the territory of the Brno - Komín district. There is made abasic analysis of the real estate structure in the district. Subsequently, realised sales transactions of flats in the period from 2014 to 2021 are set in the defined environment. Subsequently, the price and numbers within the subsets of the base set are examined and an analysis of the interdependence with the asking prices is performed. In the final part of the thesis, several hypotheses are tested and the dependence of realized prices on credit and stock market data series is examined.

Biometric fingerprint identification
Dašek, Filip ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
In biometrics we use distinctive physical features for identification and verification of identity. The most famous technique is identification by fingerprints. This technique use unique structure created by papillary lines for unambiguous identification. Thesis contains methods which were created throughout the years for analysis and adjustments of fingerprint. The algorithm is based on compairng two pairs of minitua and calculating transform matrix for correct alignment. Algorithm is tested on dataset created from LivDet databases. Performance of algorithm is represented by value EER which is compared with EERs of other algorithms tested in FVC 2006.

Face Detection and Recognition
Ponzer, Martin ; Janáková, Ilona (referee) ; Horák, Karel (advisor)
This paper discusses problems of computer vision, which deals with face detection and recognition in image and video sequence at real time. All methods are designed for color images and are based on skin detection on the basis of information of human skin color. For skin detection is used very effective method Gaussian distribution. All of the areas, which have human skin color, are classified. This classification specifies, which area is or isn’t face. For face detection is used correlation method, complete with eigenfaces method. All areas classified as a face are subsequently recognized by the eigenfaces method. Result of recognition phase is information about human identity.

Similarity Search in Network Security Alerts
Štoffa, Imrich ; Kučera, Jan (referee) ; Žádník, Martin (advisor)
Network monitoring systems generate a high number of alerts reporting on anomalies and suspicious activity of IP addresses. From a huge number of alerts, only a small fraction is high priority and relevant from human evaluation. The rest is likely to be neglected. Assume that by analyzing large sums of these low priority alerts we can discover valuable information, namely, coordinated IP addresses and type of alerts likely to be correlated. This knowledge improves situational awareness in the field of network monitoring and reflects the requirement of security analysts. They need to have at their disposal proper tools for retrieving contextual information about events on the network, to make informed decisions. To validate the assumption new method is introduced to discover groups of coordinated IP addresses that exhibit temporal correlation in the arrival pattern of their events. The method is evaluated on real-world data from a sharing platform that accumulates 2.2 million alerts per day. The results show, that method indeed detected truly correlated groups of IP addresses.

The Use of Statistical Methods for Data Processing
Čupr, Jiří ; Klučková, Martina (referee) ; Novotná, Veronika (advisor)
This master's thesis is focused on problem of orders of ingredients in McDonald's. It's an analysis of usage changes depending on outside temperature. Thesis includes theoretical background for correct analysis of the problem and possibilities to figuring it out. There is also an algorithmus for more efficient solution of problem with needs or excess of ingredients. There is also a program written in VBA language, that makes more simple usage of this algorithm on restaurants.

Acoustical detection of gunshots in the open
Hrabina, Martin ; Tučková, Jana (referee) ; Sigmund, Milan (advisor)
This work is concerned with gunshot detection and recognition. Contains overview of published works and methods used in this field. Furthermore, it lists several commercial gunshot detectors. Binary gunshot detection and recognition algorithm is proposed which discriminates between gunshot and non-gunshot sounds occuring in nature. Algorithm is tested in Matlab. Proposed algorithm is implemented in TMS320C6713 digital signal processor, achieved results are compared.

Assessment of the Economic Situation of the Parent Company Using Statistical Methods
Zborovská, Marie ; Maňáková, Marie (referee) ; Doubravský, Karel (advisor)
The master‘s thesis examines the issue of the interconnection of market potential with financial indicators and other variables. Data from the financial statements of ABC, s. r. o. operating on the Slovak IT market are used. The dependence of market potential and other market variables was evaluated using statistical methods. Subsequently, the analysis of selected financial indicators of the company ABC, s. r. o. is statistically evaluated and the dependence with market potential is verified. Thanks to the results, the company's proposals are determined, taking into account the current situation in the world.

Advanced analysis of spontaneous spoken dialogues
Musil, David ; Burget, Radim (referee) ; Atassi, Hicham (advisor)
First part of this thesis contains information about call centers. This chapter focuses at their origin and history and basic division of software call centers use. Second chapter contains ways of processing speech and methods for call quality evaluation. Next chapter provides a description of basic dialogue features such as reaction, hesitation and interruption. Following chapters contain desing and description of graphic environment designed in Matlab programming language for previously mentioned basic dialogue features from data provided by thesis supervisor and their use for conversation analysis. Second part of thesis describes the process of creation a call assessment. It includes gathering necessary data for this part of thesis, their subsequent modification, usage and discussion of results and foundings.
