Machine vision for the check of moldings
Grepl, Pavel ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
Bachelor's thesis deals with the design of arrangement of an automatic inspection unit for specified products using machine vision. The theoretical part is focused on specification of the inspection system and research in the area of machine vision components, such as cameras, lens and illumination. The practical part consists of multiple possible arrangements of the inspection unit. Solutions of the chosen arrangements, including programming and testing the application using Vision Assistant software. Finally, economic evaluation of the automation of the quality inspection using machine vision has been made.

Machine vision for locating objects
Hasík, Dávid ; Huzlík, Rostislav (referee) ; Vetiška, Jan (advisor)
The bachelor’s thesis deals with design of machine vision system for object localization and its application possibilities. Design approach, its components and their individual advantages and disadvantages for this type of machine vision system are described. This thesis also includes simple model of machine vision system for object localization using regular PC. For image processing is used Vision Assistant and its tools. Two scripts are made in this software and their performance is compared.

VC5 and Vision Designer platform visual system
Popovský, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.

Object inspection sensor
Neradilková, Aneta ; Odstrčilík, Jan (referee) ; Sekora, Jiří (advisor)
Object inspection sensor is a device that is mainly used in the automation of the production process. The Diploma Thesis deals with the familiarization of optical inspection systems, survey and comparison of companies of these systems in the Czech Republic. ELLA-CS company and dafault state output control products in her workplace is presented in the Diploma Thesis. The next part concerns the design of the inspection system for the company ELLA-CS, which is designed on the platform Raspberry. The thesis also deals with the implementation of the inspection system, which describes the hardware and software of this system. The last part is intended to discuss the results and suggestions for improving the inspection.

Recognition of Vehicle Number Plates
Martinský, Ondrej ; Zbořil, František (referee) ; Zbořil, František (advisor)
This work deals with problematic from field of artificial intelligence, machine vision and neural networks in construction of an automatic number plate recognition system. (ANPR). This problematic includes mathematical principles and algorithms, which ensure a process of number plate detection, processes of proper characters segmentation, normalization and recognition. Work comparatively deals with methods achieving invariance of systems towards image skew, translations and various light conditions during the capture. Work also contains an implementation of a demonstration model, which is able to proceed these functions over a set of snapshots.

Object Detection in Images
Vaľko, Tomáš ; Motlíček, Petr (referee) ; Švub, Miroslav (advisor)
Object detection in images is quite popular topic for years. What stands for it are a lot of works from this area of computer science. This thesis is about object classification, specifically human faces, which are one of the most interesting objects for processing. For classification we use neural networks, learned on face database. We study what influence has size of face database and preprocessing of digital image on neural network learning. This project implements simple face detector and localizator. It summarizes more and less successful results and indicates possible ways of system development in the future.

Neural Network Based Face Localization
Hendrych, Pavel ; Šiler, Ondřej (referee) ; Švub, Miroslav (advisor)
This thesis issues with possible methods for face detection and localization according to the state of the art. It describes various approaches and it is aimed at localization by neural networks and at necessary operations that have to be done before localization and after that for correct results representation. This project contains implementation of few approaches to neural netwok based face localization with emphasis on eigenfaces based face localization as well as implementation of simple classifier using distance of reconstructed face to the original one. Detailed description of implemented system, achieved results and dependecy of system performance on it's inner settings is also provided.
