Decoding of emotional visual stimuli using fMRI brain signal

摘要

Decoding human emotion induced by visual stimuli from brain signal retrieved by functional magnetic resonance imaging are proposed. Brain decoding technique with support vector machine is used to predict human emotion. Human subjective experiment are conducted by five subjects and the result shows that the accuracy of prediction is around 70% for two subjects and around 50% for other two subjects. The result of this research give the fundamental information to design brain-computer interface to predict human emotion.
