Annotation:
The essential task of a Brain-Computer Interface (BCI) is to extract the motor imagery features from Electro-Encephalogram (EEG) signals for classifying the thought process. It is necessary to analyse these obtained signals in both the time domain and frequency domains. It is observed that the sequence of multiple algorithms increases the performance of the feature extraction process. We have proposed a novel consolidated sequence of methods for feature extraction and feature reduction. The focus is given more on the feature extraction process and frequency bands, which are subject-specific frequency bands and time segments. A combination of subject specific frequency bands and time segments is a novel method-based technique that has not been utilized with EEG. This research proposes to use a combination of subject specific bands and time segments for feature extraction to solve a four-class motor imagery problem.
