Mobile Interpreter for Android
Homola, Vladimír ; Maršík, Lukáš (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis describes implementation of the Mobile interpreter application with focus on its user interface. The goal is to create an application with such interface with which the users will be able to work effectively and with pleasure. The first part contains a summary of the knowledge learned during study of this problem. After that is definition of the future user, situations in which he used it and design of system and its interface. Description of implementation and user testing is in the last part.

Automatic Text Recognition for Robots
Hartman, Zdeněk ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
This bachelor thesis describe module design for text detection and recognition for use in robotic systems. To detect charters is used Stroke Width transform, which is applied on the input edge image. In the output image after Stroke Width transform are found connected components. For letter grouping into a words is used Hough transform, which is applied on the created binary image. This image contains points, which corresponding positions of found connected components. To recognize signs in detected areas is used Tesseract library. Before recognition detected areas are extracted and rotated into a horizontal position. This proposed detector can detect even rotated text. Accuracy of detection of the text is 75% above the test set "informační tabule".

Android app - Energy Monitor with Prediction
John, Tomáš ; Herout, Adam (referee) ; Szőke, Igor (advisor)
The thesis describes process of creation mobile application used for recording and processing data from consumption energy meters. Application targets on devices with operating system Android. The task was to study similar solutions and then design and implement own one. Enriched by the possibility of predict future energy consumption, using historical outdoor temperatures. Also bring the optional OCR (Optical Character Recognition) reading meter's values. Weather data obtain from internet weather service. And from stored data be able to make user- rendly charts and statistics showing energy consumption.

Image processing using Android device - electricity meter value recognition
Sliž, Jiří ; Klečka, Jan (referee) ; Honec, Peter (advisor)
The aim of the work is to design an application for mobile devices with the Android operating system. This application allows image capturing with a camera and image processing with the support of the OpenCV library. The purpose of this application is automatic value recognition of the analog electrometer. The text contains a description of the analog electrometers. The following is characteristic of Android operating system, and this part is directly connected to a draft of the application itself. Next part contains the image processing algorithms, testing and implementation into Android application.

Optical Recognition and Analysis for Home Metering
Machala, Petr ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
The topic of this master’s thesis is a study and solution of problems regarding an optical recognition and home metering analysis for the following recording and statistical processing. For this required application a STMicroelectronics 32F429IDISCOVERY development board with ARM Cortex-M4 microcontroller and OmniVision OV7670 camera module was used, where a required firmware was implemented. This thesis therefore generally represents a complex solution from acquisition of images by used camera module to final analysis and data processing and building a functional prototype of the proposed sensor system.

Image processing using Android device - gas-meter value recognition
Wertheim, Michal ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis describes the design of the image processing for Android system, consisting of the choice of the development environment and its implementation. Workflow solution to the problem involves development of the Androidapplication and it’s graphical user interface. The text includes description of the application functionality, communicationwith a camera, storing and retrieving data. It also describes used algorithms and image processing methods used for detecting values from the counter of the gas meter.

Image processing using Android device
Hortai, František ; Petyovský, Petr (referee) ; Honec, Peter (advisor)
This thesis describes the design and workflow of creating an image processing application in Android system, and what are the possibilities in choosing development environment and how to implement them. Then I am writing about my solutions of creating applications, graphical user interface and an interface for Android. I am describing my approach in the design and functionality of the application, communication with the camera, storing and retrieving data. Further I explain which algorithms were implemented for image processing and image evaluation. Product of this thesis is a functioning application that allows to its user to capture images and video stream. The algorithm evaluates the entering data and shows the location of the number plate. The application also allows recognizing texts and numbers from images. There are other various practical features and options implemented within the application.

Test form evaluation by OCR
Noghe, Petr ; Fliegel, Karel (referee) ; Kaller, Ondřej (advisor)
This thesis deals with the evaluation forms using optical character recognition. Image processing and methods used for OCR is described in the first part of thesis. In the practical part is created database of sample characters. The chosen method is based on correlation between patterns and recognized characters. The program is designed in a graphical environment MATLAB. Finally, several forms are evaluated and success rate of the proposed program is detected.
