Optimal Detection of Multiharmonic Visually Evoked Potentials
نویسندگان
چکیده
We consider the problem of detecting visual evoked potentials (VEP's). A matched subspace lter is applied to the detection of the VEP and is demonstrated to perform better than a number of other evoked potential (EP) detectors. Unlike single-harmonic detectors, the MSF detector is suitable for detecting multi-harmonic VEP's. Moreover, the MSF is optimal in the uniformly most powerful (UMP) sense for multi harmonic signals with unknown noise variance.

Possible Long Term Effects of Chemical Warfare Using Visual Evoked Potentials
Some studies have already addressed the effects of occupational organic solvent exposure on the visually evoked potentials (VEPs). Visual system is an important target for Sulphur Mustard (SM) toxicity. A number of Iranian victims of Sulphur Mustard (SM) agent were apprehensive about the delay effect of SM on their vision and a possible delay effect of SM on their visual cortex. This investigat...
متن کاملComparison of the Wave Amplitude of Visually Evoked Potential in Amblyopic Eyes between Patients with Esotropia and Anisometropia and a Normal Group
Background: We compared the wave amplitude of visually evoked potential (VEP) between patients with esotropic and anisometropic amblyopic eyes and a normal group.Methods: The wave amplitude of VEP was documented in 2 groups of persons with amblyopia (15 with esotropia and 28 with anisometropia) and 1 group of individuals with normal visual acuity (n, 15). The amplitude of P100 was recorded mono...
متن کاملComparison Between Different Methods of Feature Extraction in BCI Systems Based on SSVEP
There are different feature extraction methods in brain-computer interfaces (BCI) based on Steady-State Visually Evoked Potentials (SSVEP) systems. This paper presents a comparison of five methods for stimulation frequency detection in SSVEP-based BCI systems. The techniques are based on Power Spectrum Density Analysis (PSDA), Fast Fourier Transform (FFT), Hilbert- Huang Transform (H...
متن کاملReal Time Driver’s Drowsiness Detection by Processing the EEG Signals Stimulated with External Flickering Light
The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...
متن کاملOn the Detection of Steady - State Visually Evoked Potentials
In this paper we develop a new method, based on the periodogram of a time-series, for the detection of steady-state VEPs. The method tests the data for the presence of hidden periodic components, which correspond to steady-state VEPs.
