Investigation of facial expression recognition system using good data of facial images based on subjective experiments

Abstract

Technologies on facial expression recognition have been widely applied to machines and robotics. According to these developments, facial expression recognition systems using artificial intelligence (deep learning) have been proposed in recent years. However, researches on facial expression recognition system based on fine facial image database are not well investigated. In this study, we developed facial image database of good data through subjective evaluation experiments for big data of SNS facial images. The experimental results show that the small good data was superior to the big data in the performance of facial expression recognition based on deep learning.
