A CNN based rotation invariant fingerprint recognition system
(Istanbul Unıv, Fac Engineering, Elektrik-Elektronik Mühendisliği Bölümü, Avcılar Kampüsü, İstanbul, 34320, Turkey, 2017)This paper presents a Cellular Neural Networks (CNN) based rotation invariant fingerprint recognition system by keeping the hardware implementability in mind. Core point was used as a reference point and detection of the ... -
An FPGA implementation of 2-D CNN Gabor-type filter
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2007)A field programmable gate array (FPGA) implementation of the Gabor-type filter is presented. The implementation uses the forward Euler approximation with optimal step size to solve the CNN cell-state equation. The FPGA is ... -
Bandpass sampling of multiband signals by using geometric approach
(IEEE, 345 E 47th St, New York, Ny 10017 USA, 2017)This paper presents a simple and fast approach to f nd a minimum sampling frequency for multi-band signals. Instead of neighbor and boundary conditions, constraints on the sampling frequency were derived by using the ... -
Decrease of event related theta coherence at left frontal-parietal connection in Alzheimer patients
(Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 USA, 2008-04-01) -
Decrease of evoked delta, theta and alpha coherences in Alzheimer patients during a visual oddball paradigm
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-10-15)In this study event related coherence of patients with Alzheimer type of dementia (AD) was analyzed by using a visual oddball paradigm as stimuli. A total of 21 mild probable AD subjects (10 untreated, 11 treated) were ... -
Decreased Evoked Right Fronto-Temporal Gamma Coherence in Acute Mania Improves After Valproate Monotherapy
(Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 USA, 2009-04-15) -
Determination of theminimum sampling frequency in bandpass sampling by geometric approach and geometric programming
(Springer, 2018-10)This paper presents a simple and fast approach to find a minimum sampling frequency for multi-band signals. Instead of neighbor and boundary conditions, constraints on the sampling frequency were derived by using the ... -
Disturbance In Long Distance Gamma Coherence In Bipolar Disorder
(Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2010-08-16)The aim of this study was to investigate long distance event-related gamma (28-48 Hz) coherence in mania before and after valproate monotherapy. Gamma coherence in response to visual oddball paradigm in ten medication-free, ... -
