Workshop Topics

This workshop explores advanced methodologies and applications of facial expression analysis for emotion understanding and mind reading across diverse scenarios and challenges. Topics of interest include, but are not limited to:
Facial expressions (including micro- and macro-expressions) analysis for emotion understanding.
4D-based methodologies for facial expression understanding, e.g., classification, detection, online recognition, generation, and transferring.
Psychological study and biologically-driven mechanism about facial expression and their links to mind reading.
Solutions for special challenges involved with the in-the-wild facial expression analysis, e.g., high heterogeneous samples of interclass, face poeses, noisy backgrounds, etc.
Applications of facial expressions recognition, 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.
Different modalities developed for mind reading, e.g., facial expressions, attentive gazes, and desensitized voices.
New data collected for the purpose of mind reading.
Applications of realistic facial expressions generation for human computer interaction or computer-mediated interactions.

Submission Guidelines

Authors are invited to submit original research papers in accordance with the Springer LNCS format. The following categories of papers are accepted:
Full papers: Minimum 12 pages.
Short papers: Minimum 6 pages.
Poster papers: Minimum 4 pages (limited number, subject to prior approval).
The Springer LNCS template can be found on the Springer LNCS guidelines page.
The review procedure is double blind. Please do not include your identity information in your submitted paper.
There are two tracks (challenge track and workshop track) for the paper submission.
For the challenge track, The top-3 teams are encouraged to submit papers to this track (Acceptance depends on the quality of the paper, so it is not guaranteed.). Other teams are also welcome to submit papers. The review criterion is based on both the team ranking and the paper quality.
For the workshop track, all work in the topic scope mentioned above is encouraged to submit. The review criterion is based on the paper quality and the relevance to 4DMR workshop.
Accepted papers (after review of at least 2-3 experts) will be published in Springer Lecture Notes in Computer Science (LNCS). We are also planning to organize a special issue, and the authors of the most interesting and relevant papers will be invited to submit an extended manuscript.
The submission link is as follow: https://easychair.org/conferences/?conf=fourdmer2026
At least one of the authors of accepted papers should register for the IJCAI-ECAI 2026 workshop and be present onsite at the workshop.
Please note that authors of workshop papers are not required to purchase full registration. Only workshop registration is needed.
