    This thesis proposes a neural network based framework to classify online Devanagari characters into one of 46 characters in the alphabet set. The uniqueness of this work is three-fold: (1) The feature extraction is just the Discrete Cosine Transform of the temporal sequence of the character points (utilizing the nature of online data input). We show that if it is used right, a simple feature set yielded by the DCT can be very reliable for accurate recognition of Devanagari handwriting, (2) The mode of character input is through a computer mouse - training the system with which will lead to jitter-robustness, and (3) We have built the online handwritten database of Devanagari characters from scratch, and there are some unique features in the way we have built up the database. Lastly, after comprehensive testing of the algorithm on 2760 characters, recognition rates of up to 97.2% are achieved

    Práce se zabývá realizací a zhodnocením měření směrových i všesměrových ultrazvukových senzorů. Řízení ultrazvukových senzorů a vyhodnocovaní vzdáleností je realizováno mikrokontrolérem Arduino Duemilanove. První část práce se zabývá měřením směrových senzorů, jejich zapojením, ovládáním a následným zpracováním hodnot v Matlabu. Druhá část práce se zabývá řešením měření a zobrazování 2D polohy všesměrovými ultrazvuky, implementaci algoritmu trilaterace pro výpočet x-ových a y-ových souřadnic a srovnání použitých filtrů. Práce ke konci obsahuje také srovnání směrových a všesměrových ultrazvukových senzorů a zhodnocení jejich použitelnosti pro měření 2D polohy.This thesis deals with the implementation and evaluation of measuring directional and omni-directional ultrasonic senzors. Control of ultrasonic senzors and computation of a distance is realized by using a microrontroller Arduino Duemilanove. The first part deals with the measurement of directional sensors, their wiring and subsequent processing of the measurement is performed in Matlab. The second part deals with solving of measuring and visualization 2D position omni-directional ultrasonic senzors, implementation trilateration algorithm for calculating x and y coordinates and comparison the used filters. At the end of this thesis also includes a comparison of directional and omni-directional ultrasound and evaluate their applicability for measuring 2D position.

    Because of the accelerating progress in biometrics research and the latest nation-state threats to security, this book's publication is not only timely but also much needed. This volume contains seventeen peer-reviewed chapters reporting the state of the art in biometrics research: security issues, signature verification, fingerprint identification, wrist vascular biometrics, ear detection, face detection and identification (including a new survey of face recognition), person re-identification, electrocardiogram (ECT) recognition, and several multi-modal systems. This book will be a valuable resource for graduate students, engineers, and researchers interested in understanding and investigating this important field of study
