Neural Network Based Edge Detection
Janda, Miloš ; Žák, Pavel (referee) ; Švub, Miroslav (advisor)
Aim of this thesis is description of neural network based edge detection methods that are substitute for classic methods of detection using edge operators. First chapters generally discussed the issues of image processing, edge detection and neural networks. The objective of the main part is to show process of generating synthetic images, extracting training datasets and discussing variants of suitable topologies of neural networks for purpose of edge detection. The last part of the thesis is dedicated to evaluating and measuring accuracy values of neural network.

Digital filters for image processing
Všetička, Václav ; Říha, Kamil (referee) ; Číka, Petr (advisor)
This work is dedicated to methods for editing the digital image. When you need an suitable algorithm to highlight the desired information from the image, or conversely, suppress disturbing elements in the picture. This work describes a few most basic image editing filters to use common in technical and medical practice. The result of this work are implementing some filters into Java.

Statistical processing of data of solar radiation in place BUT FME Brno
Nečasová, Klára ; Jaroš, Michal (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis deals with the measurement of solar radiation. The aim of this work is to determine the usefulness of solar energy and solar radiation compared to the oblique and horizontal surface. You are given basic information about solar radiation, the Solar, collectors and sensors. Further work includes measurements and calculations of solar radiation in the course of one year and at the end of the evaluation of measurement results.

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.

Evaluation of hydrodinamic load on a brdge deck
Řezník, Jindřich ; Dráb, Aleš (referee) ; Špano, Miroslav (advisor)
The subject of this thesis is the evaluation of hydrodinamic load on a physical model of a bridge deck, especially to find the relation between the median and extreme quantiles of each hydrodanamic load part and to evaluate the influence, which has the shape of the bridge deck on the size of this load. Relations, that was found may be used to determine characteristic values of loads, caused by water flow, for example, when designing the bridge bearings.

Canny's Operator and Other Useful Edge Detectors
Janda, Miloš ; Juránek, Roman (referee) ; Venera, Jiří (advisor)
This work introduces main approaches for digital image processing and defines fundamental terms for successful understanding. Main aim is description of several suitable methods used in digital image pre-processing, methods for edge detection and consequent post-processing of these. The final goal of this work is effective implementation and complex comparison of methods for edge detection.

Detection of Papillary Line Width by Fingerprints
Homola, Antonín ; Drahanský, Martin (referee) ; Lodrová, Dana (advisor)
This work outlines a method of detection of the papillary line width in fingerprints. This method is one of the possible methods of liveness detection. The first part of the work with deals defining of the fingerprint, attacks on today's systems and possibilities to improve security. The next section detection describes of the papillary line width. During the process of resolving, the first thing to do was to start operation of the scanning device and to read the database for tests and experiments. An independent application was created on this purpose. Further, there were projected methods for detection and measuring of the papillary line width. Use of the Canny edge detector with the Sobel operator and the Gaussian filter proved the best. Then, there is described implementation of individual methods. The next part of the work describes and assesses the results of the tests. The last chapter summarizes the work and proposes further possibilities of development.

Relations among elements of a triangle
Machovcová, Lucie ; Zhouf, Jaroslav (advisor) ; Dvořák, Petr (referee)
This thesis summarizes not only most of the basic components and qualities of a triangle but it also brings pieces of information about triangles which are not usually taught at elementary and high schools. The aim of the thesis is to make readers acquainted with those components and to show differences between them. There are solved constructional and arithmetical problems in the last chapter. These problems utilize relations described in the thesis. The topic of these relations goes beyond mathematical curriculum of high schools. A part of the thesis is made of pictures to imagine better the terms described and the relations of components. All of the pictures are designed in a geometrical program called GeoGebra. Key words: triangle, side, angle, altitude, median, area, perimeter.

Diverzifikace v odměňování mužů a žen
Šáchová, Pavlína
Šáchová, P., Diversification in the rewarding of Men and Women. Diploma Thesis. Brno: Mendel University in Brno, 2019. The theme of this diploma thesis is the diversification of the rewarding of men and women in two companies. First company is focused on automotive industry. The second company is focused on agriculture. The subject of investigation was accounted average gross wages and hourly wage tariffs. Based on data, which was provided by the companies has been done analysis, which was fucused on monthly and annual wages. According to lenght of employment, gender, age, and education has been done evaluation of the possible existence of wage diversification. Investigation was focused to incentive wage components too. At the end of the thesis were defined suggestions, which can be helpful for inequalities in rewarding.

Halfspace median
Říha, Adam ; Nagy, Stanislav (advisor) ; Hlubinka, Daniel (referee)
In this thesis we introduce the halfspace median, which is one of the possibilities how to extend the classical median from a one-dimensional space to spaces with several dimensions. Firstly we deal with the halfspace depth, which is a function that assigns to each point the minimum probability of a halfspace that contains it. Then we define the halfspace median and show its existence. Partially, we also deal with special types of symmetry measures for convex sets and random vectors and what follows from them, such as when the median and the center of symmetry are the same point. We also study the boundaries that, under certain assumptions, enclose the depth. We state sufficient conditions for acquiring the halfspace median, which are determined by the so-called ray basis theorem. Finally we look at the similarities of this topic with convex geometry.
