Wavelet analysis of EEG using LABVIEW

چکیده
The Electroencephalogram (EEG) is a biological signal that represents the electrical activity of the brain and is the main resource of information for studying neurological disorders. Corruption of EEG signal is caused by occurrence of various artifacts like line interference, electroculogram, electrocardiogram and muscle activity [3]. These artifacts resources increase the difficulty in analyzing the EEG signal and obtaining clinical information. So it is necessary to design a procedure to decrease such artifacts in EEG. The blanking of the EEG signal due to blinking of the patient’s eye is the problem encountered in the removal of artifact[14]. So elimination of ocular artifact called Electroculogram (EOG) from Electroencephalogram (EEG) signal using wavelet method on Laboratory Virtual Instrumentation Engineering Workbench (Lab VIEW) platform is the fundamental basis of the system. An algorithm using wavelet analysis is implemented to eliminate eye blink artifact without loss of important part of original EEG signal [1,8,11].

Comparison of STFT and wavelet transform methods in determining epileptic seizure activity in EEG signals for real-time application
Electroencephalography (EEG) is widely used in clinical settings to investigate neuropathology. Since EEG signals contain a wealth of information about brain functions, there are many approaches to analyzing EEG signals with spectral techniques. In this study, the short-time Fourier transform (STFT) and wavelet transform (WT) were applied to EEG signals obtained from a normal child and from a c...

In this paper, motor imagery EEG signals are preprocessed, using the state-of-the-art measurement and control software LabVIEW. Firstly, the elliptic filter is used for digital band-pass filtering. Then the soft-thresholding approach is adopted for wavelet denoising to enable programming with the BCI Competition 2005 dataset. The experimental results show that the method not only saves a lot of...

متن کاملEvaluation of the Hidden Markov Model for Detection of P300 in EEG Signals
Introduction: Evoked potentials arisen by stimulating the brain can be utilized as a communication tool between humans and machines. Most brain-computer interface (BCI) systems use the P300 component, which is an evoked potential. In this paper, we evaluate the use of the hidden Markov model (HMM) for detection of P300. Materials and Methods: The wavelet transforms, wavelet-enhanced indepen...
متن کاملAdaptive Segmentation with Optimal Window Length Scheme using Fractal Dimension and Wavelet Transform
In many signal processing applications, such as EEG analysis, the non-stationary signal is often required to be segmented into small epochs. This is accomplished by drawing the boundaries of signal at time instances where its statistical characteristics, such as amplitude and/or frequency, change. In the proposed method, the original signal is initially decomposed into signals with different fr...
