REMOVAL OF ELECTROENCEPHALOGRAPHY EEG EYE-BLINK ARTIFACT USING WAVELET FUNCTION

This paper presents a study related to awareness about concepts of Electroencephalography (EEG) and its one type of artifact i.e. Eye-Blink Artifact. This is one form of Ocular Artifact. To study brain functioning and problems if any, Neurologists uses Electroencephalography technique. But while recording brain signals, noise (Artifact) gets induced and became part of EEG recording. This creates problems for Nero Experts to analyze and interpret it and hence it is necessary to remove such artifact from recordings. Ocular artifact related to Eye movement is in existence which may also resemble to disordered pattern. One can detect and remove this using Wavelet Function available.Sub sampling and multi resolution analysis of signal is the key idea for identifying typical trendy pattern of required frequency band and nullifying their impact. Discrete Wavelet Transform provides sufficient information both for analysis and synthesis of the original signal.
