Human Emotion Recognition Clips Utilised Expert System was designed to recognise and interpret facial expressions of the observed person in an automatic way [1]. Still, input to HERCULES has been manually supplied. Through integrating HERCULES into the Integrated System for Facial Expression Recognition (ISFER) a complete process of automatic analysis of facial expressions has been achieved [2]...
