Simple text-independent voice lock - speaker verification software system
Kotulek, Milan ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
A brief introduction into biometrics is described in this thesis leading to description and to design a solution of verification system using speech analysis. The designed system provides firstly basic signal processing, then vowel recognition in fluent Czech speech. For each found vowel, observed speech features are calculated. The created GUI application was tested on created speaker database and its efficiency is approximately 54 % for short testing utterances, and approx. 88 % for long testing utterances respectively.
Audio-visual database for soft biometric and non-biometric traits extraction
Holeksa, David ; Balík, Miroslav (referee) ; Přinosil, Jiří (advisor)
The aim of this semester project is to design a suitable database structure for the audio-visual data, parts extracted from the data corresponding to secondary biometric and non-biometric characteristics and description of these characters. The resulting database will be used for research into the identification of audio-visual content of multimedia data.
Optimization of harvest of juveniles of pikeperch (\kur{Sander lucioperca}) taken out of ponds and following ability of the fish to adapt to system RAS
HAMPL, Jan
Within my bachelor thesis I have been trying to resolve the possibilities of optimization of harvest of juveniles of pikeperch (Sander lucioperca) taken out of ponds, and continuously I have been tracking the ability of the fish to adapt to system RAS that is applied at the experimental fish culture facilities at FROV JU. Working at the fish harvest it has shown me to be important to synchronize the work of every one of the assistants during the individual activities. The fish have been harvested in a very short time and carefully taken to already prepared transport boxes. We checked the most important parameters for the quality of water, its temperature and oxygen saturation. The mortality of the fish during the harvest and transport did not get over 2 %. Just after the transport to experimental fish culture facilities at FROV JU, to the system RAS at Vodnany, the harvested fish has been placed to 9 tanks for the weaning period. Each out of three ponds always received three tanks of harvested and adapted fish. The experiment at RAS has been divided into three parts. First part has been about the weaning period of the fish to the RAS system and the artificial food. The results were very satisfying. I have been following these parameters: SGR, FCR, increase of biomass, survival and cannibalism at the tanks. The level of survival from the pond Rohlíček has been around 83,6 %, the pond Bejkovna 69,7 % and Horažďovice 4 the level of survival was 71,8 %. After finalizing the weaning period we did biometry for 37 of selected representatives. Second part has been the 1st post-weaning period. Here I focused at the parameters such as SGR, FCR, increase of biomass, survival and cannibalism at the tanks. The level of survival from the pond Rohlíček has been around 84,17 %, the pond Bejkovna 83,83 % and Horažďovice 4 the level of survival was 82,83 %. After finalizing the 1st post-weaning period we did biometry for 37 of selected representatives. Third part has been the 2nd post-weaning period. Here I focused at the same parameters as above such as SGR, FCR, increase of biomass, survival and cannibalism at the tanks. The level of survival from the pond Rohlíček has been around 87,5 %, the pond Bejkovna 88,17 % and Horažďovice 4 the level of survival was 87,17 %. After finalizing the 2nd post-weaning period we did biometry for 37 of selected representatives, the experiment was evaluated and pikeperch juveniles were sold to the French company Asialor.
Analysis of the use of biometric methods
Ezr, Tomáš ; Doucek, Petr (advisor) ; Dianiš, Erik (referee)
Práce má za cíl seznámit se základními biometrickými prvky a používanými metodami, s jejich výhodami a nevýhodami a jejich chybovostí. Začátek práce je věnován seznámení s biometrikou, biometrickými metodami a bližšímu pohledu na metody snímání biometrických dat, jejich zpracování pomocí algoritmů a vyhodnocování. V práci je dále část věnovaná porovnání vybraných biometrických metod podle předem daných kritérií. Další část je věnována využití biometrických prvků v cestovních pasech a s tím souvisejících zákonu. V závěru jsem se pokusil přiblížit možnosti vývoje biometrických metod a zhodnotit závěry ke kterým jsem došel.
Biometrické technologie a možnosti jejich nasazení
Jurica, Martin ; Doucek, Petr (advisor) ; Bébr, Richard (referee)
Hlavním cílem této práce je, na základě sumarizace všech informací o současných biometrických systémech, které jsou relevantní pro jejich vzájemné porovnání, sestavit univerzální metodiku, kterou by bylo možno použít ke klasifikaci těchto technologií a zároveň k výběru nejvhodnější biometriky pro nasazení v libovolném prostředí. Vytvořená metodologie bude následně použita na dvou příkladech z reálného světa ? analýzu stávajícího systému pracujícího na základě ID karet v malé společnosti a následně na konceptu nasazení těchto technologií na VŠE Praha, jakožto náhrady současného systému čipových karet. Část práce také tvoří příklady výběru dle této metodiky pro modelové provozy.
