Videodetection - traffic monitoring
Kozina, Lubomír ; Beszédeš,, Marián (referee) ; Honec, Peter (advisor)
In this master’s thesis on the topic Videodetection - traffic monitoring I was engaged in searching moving objects in traffic images sequence. There are described various methods background model computation and moving vehicles marking, counting or velocity calculating in the thesis. It was created a graphical user interface for traffic scene evaluation in MATLAB.

Extension of IP Cameras Control Library
Šeptun, Michal ; Rozman, Jaroslav (referee) ; Luža, Radim (advisor)
This thesis deals with the design and implementation of the extension of the existing library to control ip cameras, mainly by supporting the motion detection, multiple cameras motion synchronization and focus view at the specific point. There are also experiments performed on the speed of the system when changing the observed point of synchronized cameras.

Tracking the movement of objects using a moving camera
Duráníková, Andrea ; Šnajder, Jan (referee) ; Králík, Jan (advisor)
The bachelor thesis deals with software for dynamic cameras with object evaluation. The first theoretical part compares programs for control of the report and data evaluation, as well as the method of motion processing, the possibilities of detecting motion and objects. The practical part implements an algorithm with the function of tracking objects, their resolution into groups and recording tracking using MATLAB.

Program for deinterlacing in video sequences of different formats
Jirků, Pavel ; Kratochvíl, Tomáš (referee) ; Slanina, Martin (advisor)
The aim of this thesis is a study of advanced algorithms for removing interlacing in digital video sequences. The first part of the work is devoted to the theory, basic knowledge and processing characteristics using multimedia data. The second part is devoted to displaying the signal using interlaced and progressive spacing. The following part is focused on methods of conversion between the interlaced line spacing and progressive spacing. The last part deals with implementation of the proposed methods. The algorithm is implemented in C++ language, which provides sufficiently fast processing algorithms. The conclusion of work is focused in testing and verification of the implemented algorithms.

Gamification of line-follower robot videorecordings
Soboňa, Tomáš ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
This bacheor’s thesis is concerned with the processing of a vehicle’s trajectory following a black line located on an unchanging white background, and subsequently comparing of the quality of each vehicle’s covered distance on this trajectory. The first part of the thesis describes the theory for recognizing the track, individual graphic tags, as well as detection of important points in the picture and their correlation with points in another picture, for which an algorithm SIFT is used. The second part deals with the description of the program, which was created as part of this work, its classes and methods. The program is written in Python, for image processing is used mainly an open source library OpenCV and, to a lesser extent, the NumPy library. Finally, the results are concluded at the end of the thesis.

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.

Visual Home Security System for iOS-Based Mobile Devices
Bajaník, Filip ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The goal of this diploma thesis is to design and implement a mobile application for home security system on the iOS platform. The application introduces a complex solution allowing the transmission of the audio and video streams between the paired mobile devices using WebRTC. The final module represents universal solution for peer-to-peer audio and video communication. The thesis also deals with the field of computer vision, namely efficient motion detection algorithms. The module for motion detection implements ViBe algorithm using Metal. In case that the motion is detected the application notifies a user with a push notification. Synchronization of application data is implemented using Cloudkit and the data persistance using Realm library.

Time Lapse from Stationary Camera Image
Ficková, Andrea ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
The goal of this thesis is to design a system which minimizes or even eliminates the restrictions of time-lapse video captured by a stationary camera. I focused on the three of these restrictions, that I had the opportunity to observe: restless objects, abrupt illumination changes, and undesirable objects. The appearance of restrictions spoils the impression of video and causes a distraction for the object of observation. Within this thesis I designed and implemented a system that can process a captured video stored in the computer and capture time-lapse video from a video stream. The goal of the designed system is to apply one of the algorithms to the corresponding restriction. The main result is the production of a time-lapse video, which will be more pleasant for their observers to watch.

Hiding Moving Objects in Video Sequences
Dostál, Martin ; Zahrádka, Jiří (referee) ; Španěl, Michal (advisor)
Hiding moving objects in video sequences is an interesting topic in computer vision. In this thesis, a real-time single object tracking and removal method is proposed. An input video is assumed to be captured with static video camera. Motion detection is based on a background subtraction using Mixture of Gaussians as the representation of background. The object tracking is realized by a combination of blobs comparison and computation of optical flow using Lucas-Kanade method. Consequent object removal makes use of created background model.
