Moeslund Gholamreza Anbarjafari TI Two-stage Recognition and Beyond for Compound Facial Emotion Recognition SO Electronics JI ELEC PY 2021 BP 2847 VL 10 IS 22 DE compound emotion recognition; facial expression recognition; dominant and complementary emotion recognition; deep learning AB Facial emotion recognition is an inherently complex problem due to individual diversity in facial features and racial and cultural differences. Moreover, facial expressions typically reflect the mixture of people’s emotional statuses, which can be expressed using compound emotions. Compound facial emotion recognition makes the problem even more difficult because the discrimination between dominant and complementary emotions is usually weak. We have created a database that includes 31,250 facial images with different emotions of 115 subjects whose gender distribution is almost uniform to address compound emotion recognition. In addition, we have organized a competition based on the proposed dataset, held at FG workshop 2020. This paper analyzes the winner’s approach—a two-stage recognition method (1st stage, coarse recognition; 2nd stage, fine recognition), which enhances the classification of symmetrical emotion labels.
