Micro-expressions are facial movements that are extremely short and not easily detected, which often reflect the genuine emotions of individuals. Micro-expressions are important cues for understanding real human emotions and can be used for non-contact, non-perceptual deception detection, or abnormal emotion recognition. It has broad application prospects in national security, judicial practice, health prevention, and clinical practice. However, micro-expression feature extraction and learning are highly challenging because they are typically short in duration, low intensity, and have local facial asymmetry. In addition, the intelligent micro-expression analysis combined with deep learning technology is also plagued by the problem of relatively small data samples. Not only is micro-expression elicitation very difficult, micro-expression annotation is also very time-consuming and laborious. More importantly, the micro-expression generation mechanism is not yet clear, which shackles the application of micro-expressions in real scenarios. FME'23 is the inaugural workshop in this area of research, with the aim of promoting interactions between researchers and scholars from within this niche area of research. This year we hope to discuss the growing ethical conversations when using face data, and how we can come to a consensus on micro-expression standards within affective computing.
