Mobile App for Editing and Viewing Simple Weekly Schedules
Džubarová, Romana ; Škandera, Juraj (referee) ; Herout, Adam (advisor)
The aim of this work is to create a mobile application that will write down the regular weekly activities of the user. Users are not only university or high school students, but the application is intended to appeal to all people who need to register for regular activities during the week. Users can create activities which are inserted into the table. These activities can be changed or deleted. The application allows you to create a test task. It is possible to set a notification for the exams, which the user will receive at the time of the exam, or he can change this time in the Settings. The user can also change what his table will look like in Settings. He can change the days on which he wants to record activities or the start and end time of activity. The application can also be set to dark mode to save battery life. The bachelor thesis describes the design, implementation, testing, and also future intentions for my mobile application.

Streaming Ray Tracer on GPU
Dvořák, Jakub ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
Current consumer GPUs can be used as high performance stream processors and are a tempting platform to be used to implement raytracing. In this paper I briefly present raytracing principles and methods used to accelerate it, modern GPUs programmable pipeline and examples of its use. I describe stream processing in general and available interfaces enabling the usage of GPU as stream processor. Then I present my GPU raytracer implementation, used algorithms and experiments I have made.

Reconstruction of 3D Information about Vehicles Passing in front of a Surveillance Camera
Dobeš, Petr ; Sochor, Jakub (referee) ; Herout, Adam (advisor)
This master's thesis focuses on 3D reconstruction of vehicles passing in front of a traffic surveillance camera. Calibration process of surveillance camera is first introduced and the relation of automatic calibration with 3D information about observed traffic is described. Furthermore, Structure from Motion, SLAM, and optical flow algorithms are presented. A set of experiments with feature matching and the Structure from Motion algorithm is carried out to examine results on images of passing vehicles. Afterwards, the Structure from Motion pipeline is modified. Instead of using SIFT features, DeepMatching algorithm is utilized to obtain quasi-dense point correspondences for the subsequent reconstruction phase. Afterwards, reconstructed models are refined by applying additional constraints specific to the vehicle reconstruction task. The resultant models are then evaluated. Lastly, observations and acquired information about the process of vehicle reconstruction are utilized to form proposals for prospective design of an entirely custom pipeline that would be specialized for 3D reconstruction of passing vehicles.

Mobile App for Shared Shopping
Šťastná, Barbora ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
The goal of this thesis is to create a mobile application for the Android operating system, which makes organizing a community shopping easier for its users and their friends. Each user can build a community of their own that offers collective purchasing of products, or can offer their products for purchase. They categorize these offers to their channels and their friends choose only those channels that they find interesting. If their friends accept their offer, they see the necessary information about their individual purchases. Thus, this application enables users to offer shared purchasing to their friends e.g. at a grower from whom these people could not buy individually. They can procure quality produce together at a competitive price and they can also reduce production of plastic packaging by purchasing as a group.

Android IP Camera
Chvála, Jan ; Havel, Jiří (referee) ; Herout, Adam (advisor)
The goal of this thesis is to design a system which would allow video data streaming from a mobile device and real time playback using a standard web browser. The technological background and the implementation platform are both part of this thesis. Web Real Time Communications (WebRTC) technology was used for acquiring multimedia data on mobile device. This technology is natively supported in the latest major web browsers and in WebView component (Android version 5.0 and above). Sending push notifications from a server to a mobile device to start the streaming is done with Google Cloud Messaging technology. The resultant system allows a user to start the application on mobile device with easy web browser access. This starts the multimedia stream from device, which can be parametrized and secured by password. The benefit of this thesis is the overview of WebRTC technology and its demonstration. The IP camera implementation shows how easy it is to use the WebRTC in real applications.

Vegetation Detection in Images
Černá, Tereza ; Herout, Adam (referee) ; Přibyl, Bronislav (advisor)
This project focuses on detection of vegetation in digital image and describes approaches to detect vegetation. Created aplication uses grass detection method in video in real time. There is a new mean of evaluation of the method proposed in this project, using commonly used pixel by pixel detection and also a new detection approach, segment detection. Functionality of the application is checked by set of test images. The thesis is concluded by comparing results of those two approaches. Success of correctly detected vegetation ranges up to 86.32 %.

Prototyping of Photographic Composition Using Augmented Reality
Salát, Marek ; Szentandrási, István (referee) ; Herout, Adam (advisor)
The thesis deals with an image processing problem called image matting. The problem involves detection of a foreground and background in an image with minimal user interaction using trimaps. Foreground detection is used in image composition. The goal of the thesis is to apply already known algorithms, in this case A Global sampling matting, in an Android application. The most important result is an intuitive application that can be used for making creative viral photos. Agile methodology is applied throughout the whole application development cycle. From the very beginning, the application is publicly available as a minimum viable product on Google play. The work’s contribution is in optimization of the mentioned algorithm for use in mobile devices and parallelization on a GPU, together with a publicly available application.

License Plate Detection and Recognition for Traffic Analysis
Černá, Tereza ; Hradiš, Michal (referee) ; Herout, Adam (advisor)
This thesis describes the design and development of a system for detection and recognition of license plates. The work is divided into three basic parts: licence plates detection, finding of character positions and optical character recognition. To fullfill the goal of this work, a new dataset was taken. It contains 2814 license plates used for training classifiers and 2620 plates to evaluate the success rate of the system. Cascade Classifier was used to train detector of licence plates, which has success rate up to 97.8 %. After that, pozitions of individual characters were searched in detected pozitions of licence plates. If there was no character found, detected pozition was not the licence plate. Success rate of licence plates detection with all the characters found is up to 88.5 %. Character recognition is performed by SVM classifier. The system detects successfully with no errors up to 97.7 % of all licence plates.

Flight Game for Android
Šabata, David ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
This work deals with flight game development on Android platform. Firstly the possibilities of native development and development using Libgdx library will be discussed. Then flight mechanics of a real aircraft and simplified mechanics used in flight games will be explained. The work will also summarize current trends in mobile flight game controls and will propose a new control method based on touch input. Using this method a flight game will be designed and implemented. In the end of this work the process of testing and publishing will discussed, as well as possibilities of further development.
