Text to Audio Alignment
Šuba, Adam ; Hradiš, Michal (referee) ; Szőke, Igor (advisor)
This bachelor thesis studies a tool for automatic text to audio alignment at the level of single phonemes and graphemes. It also discusses possible techniques used in alignment and possible limitations and difficulties that need to be taken into account. Studied tool uses approach based on grapheme-to-phoneme conversion using joint-sequence models. Data used in experiments are TV broadcast recordings from Multi-Genre Broadcast Challenge 2015.

Synthetic Fingerprint Generation from Biometric Template
Šuba, Adam ; Tinka, Jan (referee) ; Kanich, Ondřej (advisor)
The goal of this master thesis is to design and implement an approach for synthetic fingerprint generation from a biometric template. The thesis bases the solution on an existing fingerprint generator called SyFDaS developed at the Brno University of Technology, Faculty of Information Technology. Individual components of the generator had to be modified and automized to suit better the task of generating from a template. The end product enables the user to create a fingerprint without any intervention just by importing a template. The evaluation in this thesis presents results obtained by comparing the synthetic and original fingerprints using the VeriFinger algorithm. Entirely automatically created fingerprints achieved mixed results; however, manual adjustments of the parameters brought substantial improvements. Up to 72% of synthetic fingerprints reached the match by the VeriFinger. The results of the evaluation helped to identify weak points of the current solution. Based on these, the thesis proposes further steps to improve the success rate of automatic generation and the quality of other components.
