Vehicle On-Board Camera Analysis
Kadeřábek, Jan ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
This thesis focuses on analysis of video from vehicle on-board camera. During the process of analysis, probihibitory traffic signs are detected and their specific type is classified. For recognized speed limit signs, their numeric value is extracted. From the processed information, it will try to create a file containing the unique occurrences of traffic signs including their GPS coordinates. For the purpose of detection and recognition of traffic signs, several data sets were created. A~cascade classifier with LBP features is used as a detector. Classification of the type and value of traffic signs is done using the k-Nearest Neigbour method.

Detection of Red-Light Violation
Šorf, Milan ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
This thesis is focused on automatic detection of red-light violation using static camera. Theoretical part of the thesis describes the principle of detection and introduces various methods of detecting traffic lights and cars as well as their reliability metrics. The thesis also illustrates implementation of the application for evaluation of these methods.

Web Tool for Testing Based on Q-Sorting
Persich, Alexandr ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
Q-sorting is one of many methods used to determine people's subjectivity. The main goal of this thesis is to present ways used to design and create web application for Q-sort method. I have been focusing mainly on designing user interface which greatly affects the number of successfully finished surveys. To accomplish this, I have used common web technologies. The result is a web tool which allows to create and manage new surveys. For respondents it provides simple and intuitive user interface which makes the process of Q-sorting easier.

Web Tool for Testing Based on Q-Sorting
Mička, Vojtěch ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
This thesis describes process of designing user interface and implementing online q-sort application. The primary goal is to design the user interface as similar as possible to the classic q-sort with graspable elements, and to solve problem of easy understandeable layout with many functional stand alone elements on the limited size of monitor. The thesis describes the process of designing, implementing and testing of the application and it includes experiment for validation of application useability. The outcome of this thesis is an online application for q-sorting and the text of thesis documanting whole process of implementation.

Motion Detection in Video
Půček, Petr ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
This bachelor thesis deals with motion detection in video recorded on stationary camera. It describes the process of solution and implementation of motion detection app on Windows platform using OpenCV library for image processing. These principles of image analysis and processing can be used in any other systems.

Fast Detection of Natural Objects
Zelinka, Martin ; Bartl, Vojtěch (referee) ; Šimon, Martin (advisor)
Thesis deals with the detection and localization of dogs in the image. It analyzes computer vision techniques suitable for solving this problem. It is designed and then implemented solution. Data set of images representing the object of the search and the data set of negative images are created. The resulting solution is finally subjected to training in order to determine the best parameters for used algorithms. The resulting program is included in the attached DVD.

User Interface of Calendar for Seniors
Ryndová, Markéta ; Bartl, Vojtěch (referee) ; Beran, Vítězslav (advisor)
Bachelor thesis deals with the design and implementation of an user interface of a calendar for seniors through modern web technologies. Main part of this bachelor thesis was finding out user's needs and making suitable components layout for both roles - patient and keeper. Main point was cooperation with test's subjects.

Realistic Visualisation of Alcoholic Beverages
Bartl, Vojtěch ; Kučiš, Michal (referee) ; Polok, Lukáš (advisor)
The object of thesis was to make a simple program for visualisation of alcoholic beverages. There was used a global illumination method raytracing, which serve the purpose to visualize 3D scene in photorealistic quality. The rays sent to the scene reflects and refracts on the interfaces and getting information about color of materials. Finally the ray determine the color of pixel. It's a very complicated process where it is necessary to solve passing rays through different interfaces.

Mapping the Motion of People by a Stationary Camera
Bartl, Vojtěch ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
The aim of this diploma thesis is to obtain information on the motion of people in a scene from the record of the stationary camera. The procedure to detect exceptional events in the scene was designed. Exceptional events can be fast-moving persons, or persons moving in di erent places than everyone else in the scene. To trace the motion of persons, two algorithms were applied and tested - Optical flow and CAMSHIFT. The analysis of the resulting motions is performed by monitoring the progress of motion, and its comparison with the other motions in the scene. The analysis result is represented by detected exceptional motions that can be found in the video. The areas where the motion occurs in the scene, and where the motion is the most common are also described together with the motion direction analysis. The exceptional motion parts extracted from the video represent the main result of the work.
