Survey of Infant Emotion Recognition

Infant emotions significantly influence their cognitive development and self-awareness, playing a crucial role in their growth. The field of infant emotion research currently confronts challenges such as insufficient emotion datasets, non-uniform quantification standards, and limited accuracy in emotion recognition. Therefore, effectively recognizing infant emotions has become a central issue in this field. This paper reviews and summarizes current research on infant emotion recognition, focusing on infant emotion datasets, representation models, and classification methods across various modalities. Initially, it enumerates and introduces available public datasets. Subsequently, it analyzes common models for representing infant emotions and methods for classifying them. Finally, it outlines existing challenges and discusses future research directions, aiming to guide further studies. © 2024 Journal of Computer Engineering and Applications Beijing Co., Ltd.; Science Press.
