Welcome to participate in the 1st Workshop & Challenge on Micro-gesture Analysis for Hidden Emotion understanding (MiGA) workshop.
Our MiGA workshop will be held at the IJCAI conference on 19th-23th August, Maco, China!
We warmly invite researchers to submit your recent research work to our MiGA workshop.
Accepted papers will be published at the IJCAI conference in 2023, which is the leading conference in the field of artificial intelligence.
The topic includes but is not limited to:
• Gesture and micro-gesture analysis for emotion understanding.
• Vision-based methodologies for gesture-based emotion understanding, e.g., classification, detection, online recognition, generation, and transferring.
• Solutions for special challenges involved with the in-the-wild gesture analysis, e.g., severely imbalanced sample distribution, high heterogeneous samples of interclass, noisy irrelevant motions, noisy backgrounds, etc.
• Different modalities developed for emotion understanding, e.g., body gestures, attentive gazes, and desensitized voices.
• New data collected for the purpose of hidden emotion understanding.
• Psychological study and neuroscience research about various body behaviors and their links to emotions.
• Hardware/apparatuses/imaging systems developed for the purpose of hidden emotion understanding.
• Applications of gestures and micro-gestures, e.g., for medical assessment in hospitals (ADHD, depression), for health surveillance at home or in other environments, for emotion assessment in various scenarios like for education, job interview, etc.
We are looking forward to interesting presentations, insightful discussions, and new collaborations!
Besides, we are hosting the first MiGA challenge!
Welcome to join our challenge with two fundamental challenge tasks (Tracks), including (Track 1) micro-gesture classification and (Track 2) micro-gesture online recognition. Participating teams can choose to compete on one or both tasks. The challenge will be organized on the CodaLab website.
