Tone and Chord Recognition as an Android Application
Kucharovič, Oliver ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
The aim of this work is to recognize tones and chords on any musical instrument using the microphone on Android mobile devices. The app scans or records the sounds which are analyzed. It writes to a visual representation which is similar to the musical notation. The work describes the problems of recognition and the solution of the problem using fast Fourier transformation and analysis of the spectrum of volumes. Work describes the theory of music and the training of individual tones. The application was subjected to user tests and recognition accuracy tests. The conclusion includes tests results and statistics from the Google Play publication.

Smart Sensor Network with Using Mobile Devices
Tomčík, Milan ; Zbořil, František (referee) ; Samek, Jan (advisor)
This bachelor thesis deals with the use of mobile devices as sensors of various activities. Different types of mobile device sensors are used, in particular the gyroscope, accelerometer and magnetometer. The thesis tackles the possibility of utilization of mobile devices as part of the nodes in a sensor network, while employing mobile device and fusing data obtained from their sensors.
