METHOD FOR DETECTING BRAIN WAVE PROPERTY CHANGE USING INFORMATION ENTROPY AND GINI COEFFICIENT

摘要

The present invention relates to a method for detecting brain wave property change using information entropy and Gini coefficient. According to the present invention, the present invention includes a step of measuring potential change from an electrode attached to scalp or cerebral cortex, a step of obtaining information entropy by using the potential change measured in a constant time range according to each channel, a step of calculating Gini coefficient by using the information entropy obtained in each channel, and a step of detecting the change of brain wave property by using the calculated Gini coefficient. According to the present invention, the change of brain wave property can be accurately detected by using the variation of Gini coefficient.;COPYRIGHT KIPO 2014
