Research on Multi-feature Fusion Algorithm for Facial Expression Recognition System
Yingying Wang, Yibin Li, Yong Hua Song, Xuewen Rong · 2018
Facial expression recognition has played a significant role in harmonious human-computer interaction, and feature extraction is the key step for the final recognition result. In the part of feature extraction, a fusion information generally has a number of advantages over a single feature information. The traditional serial features fusion technique is the most common fusion method, but there is a constant problem existing in the above fusion method: the curse of the dimension. For solving the problem, a new fusion method is proposed. Extensive experiments illustrate that the new image fusion method has higher recognition rate and better realtime.
