GROUP EMOTION INFERENCE SYSTEM BASED ON AMOUNT OF MOVEMENT THROUGH IMAGE INFORMATION

摘要

A method for determining group emotion comprises the steps of: acquiring image data for a subject group; preprocessing the image data to extract first data during a predetermined interval of time and second data preceding the first data during a predetermined interval of time longer than the first data; processing the first data and the second data to calculate at least one among the increase and decrease of a first data frequency for the second data and an average of the first data and the second data; and comparing the increase and decrease or an average difference of the first data and the second data to evaluate emotional state of the subject group.;COPYRIGHT KIPO 2017
