Using Facial Expression Recognition for Crowd Monitoring

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10749)

Abstract

In recent years, Crowd Monitoring techniques have attracted emerging interest in the field of computer vision due to their ability to monitor groups of people in crowded areas, where conventional image processing methods would not suffice. Existing Crowd Monitoring techniques focus heavily on analyzing a crowd as a single entity, usually in terms of their density and movement pattern. While these techniques are well suited for the task of identifying dangerous and emergency situations, they are very limited when it comes to identifying emotion within a crowd. In this work, we propose a novel Crowd Monitoring algorithm based on estimating crowd emotion using Facial Expression Recognition (FER). By isolating different types of emotion within a crowd, we aim to predict the mood of a crowd even in scenes of non-panic. To validate the effectiveness of the proposed algorithm, a series of cross-validation tests are performed using a novel Crowd Emotion dataset with known ground-truth emotions. The results show that the algorithm presented is able to accurately and efficiently predict multiple classes of crowd emotion even in non-panic situations where movement and density information may be incomplete.
