Image Descriptors and their Usage for Object Detection
Bature, Jonathan ; Druckmüllerová, Hana (referee) ; Procházková, Jana (advisor)
Detekce obličeje v obrazech je široce prozkoumaným tématem v počítačovém vidění. Algoritmus která umožnila rozpoznání obličeje a stanovila nové standardy v této oblasti byla Viola-Jones algoritmus. Tato práce popisuje a vysvětluje vlastní implementaci obličeje detektor založený na algoritmu Viola Jones pomocí Matlab CascadeObjectDetector. Tato diplomová práce přispívá ke zkoumání technik, jako je hlavní součást analýza (PCA) pro rozměrovou redukci deskriptorů pro stanovení detekce objektu systém, který dosahuje nejlepšího kompromisu mezi výkonem a rychlostí. V našem přístupu, detekce obličeje se provádí analýzou hlavních součástí (PCA). Obraz obličeje je promítnutý do prostoru obličeje, který kóduje nejlepší variace známých obrazů obličeje. The prostor obličeje je definován vlastní tváří. Vlastní tvář je sada obličejových vlastních vektorů které nemusí odpovídat běžným rysům obličeje, jako jsou oči, nos a rty. Systém funguje tak, že promítá předem extrahované obličejové obrazy do řady obličejových prostorů které představují velké odchylky mezi známými obrazy obličeje. Obličeje jsou klasifikovány jako známé nebo neznámé tváře po porovnání s existujícím obrázkem tváře v databázi.

Active stereo vision
Doležal, Milan ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
This thesis deals with active stereo method for measurement of objects with transparent layer. In theoretical part of this thesis is described method of active triangulation and method of active stereo. After that, there is research of articles focused on transparent layer in optical measurement. Next chapters deal proposition of measuring system, it's parameters, calibration, procedure and evaluation of measurement. MATLAB was selected as programming platform.

Evaluation of Supllier Risk Using Fuzzy Logic
Lázniček, Matěj ; Janková, Zuzana (referee) ; Dostál, Petr (advisor)
This diploma thesis deals with the evaluation of supplier risk for a chosen company Vinařství Soška using the fuzzy logic principles. This company like many others is forced to shift its sales to the Internet environment due to the government restrictions established to reflect the pandemic situation. For a successful Internet business, it is necessary to choose an optimal ecommerce software based on the company requirements. For this purpose, two fuzzy logic models are built in Microsoft Excel and MATLAB software. Their aim is to evaluate the potential risk of all of the suppliers. Based on this evaluation, the results are transformed into specific recommendations on how to choose the optimal solution for the company. The first chapters deal with the general theory that is later used in the analytical part.

Force loading of cutting tools during the machining process
Vančura, Tomáš ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
The theoretical part of the diploma thesis summarizes a knowledge of the force loading of the cutting tools and state of the art in the cutting force measurement. In the experimental part, work deals with the development of the software for a force records analysis. The main objective of the software is to automatise the processing and analysis of the measured force records. The functionality of the newly created software was verified by evaluating the circle-segment end mills experiments performed at the Institute of Manufacturing Technology of the Faculty of Mechanical Engineering, BUT.

Investment Optimization
Bujnovský, Daniel ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This work is focused on description of two models of mathematical programming - the network model and the Markowitz portfolio model, their connection and application in transportation problems. The goal of the practical section is to approach the description of these problems to the real situations and look for their efficient solutions at the same time. All of that is accompanied by examples on real data from capital market or own model data. The theoretical considerations and thoughts are implemented in programming language Matlab. All results are explained in context to both models. The thesis also includes the introduction to economical and statistical theory which is necessary to understand the problem.

Automatic delineation of ECG signals
Žiak, Milan ; Smital, Lukáš (referee) ; Vítek, Martin (advisor)
This thesis deals about automatic delineation of ECG. We use algorithm, which is descriped by autors Lagune, Jané and Caminale. Their work uses first derivation for delineation ECG signal. This bachelor thesis also uses a wavelet transform to reach better results.

Automatic detection of stress using biological signals
Votýpka, Tomáš ; Kozumplík, Jiří (referee) ; Smíšek, Radovan (advisor)
Bachelor's thesis is focused on stress detection. This thesis defines the concept of stress, analyzes the appropriate biological signals for stress detection, presents databases of biological signals, that were used for stress detection and mentions methods of automatic stress detection. Then, a stress detection program was implemented in the MATLAB software environment. A freely available database of non-EEG signals was used to implement the program. Models classifying stress were created using 4 machine learning methods for binary classification and 3 machine learning methods for classifying 4 psychical states. Efficiency of the classification was summarized in the conclusion of this thesis.

Retinal biometry with low resolution images
Smrčková, Markéta ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis attempts to find an alternative method for biometric identification using retinal images. First part is focused on the introduction to biometrics, human eye anatomy and methods used for retinal biometry. The essence of neural networks and deep learning methods is described as it will be used practically. In the last part of the thesis a chosen identification algorithm and its implementation is described and the results are presented.

The Application of Fuzzy Logic for Evaluation of Quality of Customers
Homola, Rostislav ; Kudrna, Josef (referee) ; Dostál, Petr (advisor)
Master thesis deals with quality evaluation customers of Heineken Česká republika, a. s. using the theory of fuzzy logic as an advanced decision-making method, which will be further practically applied within the design of the solution. Based on the selected parameters, a model will be developed to optimize the value of the company's customers, on the basis of which the company may also decide whether to cooperate with the customer or it is more advantageous for them to terminate this cooperation. The work itself is supported by Microsoft Excel and MATLAB.
