Analysis of EEG using Variational Mode Decomposition Method for Diagnosis of Epilepsy

摘要

EEG represents electrical activity of the brain. Various brain disorders can be analyzed from the information that can be extracted from EEG signal. Extraction of relevant information from EEG is an arduous task due to the highly chaotic nature of EEG signal. Various signal processing techniques can be employed for this process. Variational mode decomposition(VMD) technique involves decomposition of EEG into sub bands characterized by limited bandwidth and characterized by center frequency. The value of center frequency is extracted for the sub bands and the value is analyzed as a parameter for diagnosing normal EEG and diseased EEG.
