Augmented Reality for iPhone
Bednář, David ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
This Bachelor's Thesis was performed during a study stay at the "Technische Universität Graz", Austria. This Thesis talks about handheld augmented reality, especially for the iPhone. In theoretical part of the Thesis, we discuss available frameworks and description of the platform itself and its application development. The practical part describes development of a demonstrational AR application, which uses popular OpenCV computer vision library for processing the image captured by iPhone's camera. The application also permits to overlay visual information above the camera preview (with and without the use of private APIs) and also permits to align OpenGL camera to the position of the iPhone's camera in the real world.

Real-time text translation with using mobile devices
Sztefek, Lukáš ; Rozman, Jaroslav (referee) ; Samek, Jan (advisor)
The aim of this thesis is design and implementation of Android application which will serve as real-time translator from one language to another, including several world languages and Czech. The text obtained from image is translated and replaces the original one with keeping its visual look as much as possible. The reader gradually gets familiar with getting text from images, text translation, displaying text on mobile device and Android OS implementation. In conclusion, the experiments with multiple input images and comparison of existings applications have been done.

Mobile System for Text Recognition on Android
Tomešek, Jan ; Kolář, Martin (referee) ; Zemčík, Pavel (advisor)
This thesis deals with creation of a mobile library for preprocessing of images with text which represents a part of a system for text recognition. The library is realized with emphasis on generality of use, efficiency and portability. The library providing a set of algorithms primarily for image quality assessment and text detection was created in this thesis. These algorithms enable a substantial decrease in volume of transmitted data and speed up and refinement of the recognition process. An example application for the Android platform able to analyze composition of foods stated on their wrappings was created as well. Overall, the library (system) simplifies development of mobile applications with focus on text extraction and analysis. The mobile application then provides a comfortable way of food harmfulness verification. The thesis offers a reader an overview of current solutions and tools available in this field, it provides a breakdown of important image preprocessing algorithms and guides him through the construction of the library and the application for mobile devices.

Echo-Based Distance Measurement on Mobile Phone
Richter, Jiří ; Maršík, Lukáš (referee) ; Černocký, Jan (advisor)
Cílem této práce je vytvoření aplikace pro mobilní zařízení na měření vzdálenosti pomocí ozvěny. Zaměřuje se na testování komponent zařízení a výběr signálu s vhodnými parametry pro měření. První částí práce je vyhodnocení schopnosti zařízení přehrávat a nahrávat zvuk, výsledkem je určení frekvence a síly zvuku, se kterým je zařízení schopno pracovat. Práce dále popisuje algoritmus pro měření vzdálenosti založeny na vzájemné korelaci vyslaného a přijatého signálu. Další částí je popis implementace výše zmíněného algoritmu v aplikaci pro operačním systému Android s řešením komunikace a synchronizace mezi jednotlivými součástmi. Implementace navrženého algoritmu v aplikace je v závěru práce otestována. Na základě zjištěných údajů je možné měření vzdálenosti na mobilním zařízení od půl metru do přibližně tří metrů, s ohledem na okolní hluk, s přesností na desetinu metru.

Android Music Player with the Song Selection by a Device Context
Chmelařová, Gabriela ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Tato práce pojednává o vytvoření mobilní aplikace zvažující kontext zařízení, která vybírá a doporučuje hudební skladby dle aktuálního stavu kontextu zařízení. Kontext je získáván na základě naměřených hodnot, které jsou získány z vestavěných senzorů mobilního zařízení a z ostatních systémových hodnot zařízení. Výběr konkrétní skladby je poté založen na výstupu modelu strojového učení, který klasifikuje kontext na základě aktuálních získaných dat a následně zvolí skladbu připadající k danému kontextu.

Interactive Foreground/Background Segmentation on Mobile Phone
Studený, Petr ; Szentandrási, István (referee) ; Herout, Adam (advisor)
This thesis deals with the problem of foreground extraction on mobile devices. The main goal of this project is to find or design segmentation methods for separating a user-selected object from an image (or video). The main requirement of these methods is the image processing time and segmentation quality. Some existing solutions of this problem are mentioned and their usability on mobile devices is discussed. A mobile application is created within the project, demonstrating the implemented real time foreground extraction algorithm.
