    • Acceleration of feature extraction for FPGA-based speech recognition 

      Arminas, Vytautas; Tamulevičius, Gintautas; Navakauskas, Dalius; Ivanovas, Edgaras (Photonics Applications in Astronomy, Communications, Industry, and High-Energy Physics Experiments, Wilga, Poland, 24-29 June 2010 : proceedings / The International Society for Optical Engineering, 2010)
      The paper describes a field programmable gate array implementation of the main part of speech recognition system - feature extraction. In order to accelerate recognition the whole cepstral analysis scheme is implemented ...

    • Ant system implementation using Microblaze: some preliminary results on efficiency study 

      Laptik, Raimond; Arminas, Vytautas; Navakauskas, Dalius (Elektronika ir elektrotechnika, 2009)
      The paper presents some preliminary results on efficiency study of Ant System implementation using software processor Microblaze. By the use of Monte-Carlo tests of number π calculation the best use of Pseudo-Random Number ...

    • Automated synthesis method for inhomogeneous delay systems using artificial neural networks 

      Katkevičius, Andrius; Martavičius, Romanas (22nd International Conference “Electromagnetic Disturbances EMD’2012”, 2012)
      All new microwave devices, including delay systems, are designed by using computer-aided design systems which are managed by specialized software packages. Automated simulation of microwave devices using analytical and ...

    • Calculation of characteristics of meander slow-wave system with additional shields 

      Metlevskis, Edvardas; Martavičius, Romanas (22nd International Conference “Electromagnetic Disturbances EMD’2012”, 2012)
      In this paper a study of meander slow-wave system with additional shields is performed. Aim of a study is to determine an impact of different topologies of meander edges on dispersion properties of a system. Three ...

    • Deep neural network-based feature descriptor for retinal image registration 

      Šabanovič, Eldar; Stankevičius, Gediminas; Matuzevičius, Dalius (2018 IEEE. 6th workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE), November 8-10, 2018 Vilnius, Lithuania : proceedings / edited by: Dalius Navakauskas, Andrejs Romanovs, Darius Plonis, 2018)
      Feature description is an important step in image registration workflow. Discriminative power of feature descriptors affects feature matching performance and overall results of image registration. Deep Neural Network-based ...

    • Efficiency of initial FPGA implementation of Lithuanian isolated word recognition system 

      Navakauskas, Dalius; Tamulevičius, Gintautas; Arminas, Vytautas; Ivanovas, Edgaras; Martavičius, Romanas (33th International conference on fundamentals of electrotechnics and circuit theory "IC-SPETO - 2010", Gliwice, Ustron, Poland, 26-29.05.2010 = XXXIII Międzynarodowa konferencja z podstaw elektrotechniki i teorii obwodow, 2010)
      Isolated word recognition system can be built cheaper and faster if implemented in FPGA and thus it is the most desirable technology to be included as a mean of communication with mobile devices. The paper deals with ...

    • Experimental study of spectrum sensing algorithm with low cost SDR 

      Stašionis, Liudas; Serackis, Artūras (22nd International Conference “Electromagnetic Disturbances EMD’2012”, 2012)
      Development of the efficient algorithm for the spectrum sensor for cognitive radio is slowed by the lack of experiments within a real environment. In this paper we suggest to use a low cost software defined radio (SDR) ...

    • Hardware accelerated FPGA implementation of Lithuanian Isolated Word Recognition System
