Dear Colleagues,

Please find below the invitation to contribute to the 9th Workshop and Competition on Affective & Behavior Analysis in-the-wild (ABAW) to be held in conjunction with the International Conference on Computer Vision (ICCV), 2025.



(1): The Competition is split into the below three Challenges:

i) Valence-Arousal Estimation Challenge
ii) Compound Expression Recognition Challenge
iii) Fine-Grained Violence Detection Challenge


The first Challenge is based on an augmented version of the Aff-Wild2 database; the 2nd Challenge is based on the C-EXPR-DB database; and the 3rd Challenge is based on the DVD Database. More details can be found on the Workshop's website.

All accepted papers from the Competition will be part of the ICCV 2025 proceedings.


Important Dates:

- Call for participation announced, team registration begins, data available:
3 June, 2025

- Final submission deadline:
3 July, 2025

- Winners Announcement:
5 July, 2025

- Final paper submission deadline:
8 July, 2025

- Review decisions sent to authors; Notification of acceptance:
12 August, 2025

- Camera ready version deadline:
18 August, 2025




(2): The Workshop is a premier platform highlighting the latest advancements in multimodal analysis, generation, modeling, and understanding of human affect and behavior in real-world, unconstrained environments.
Original high-quality contributions, in terms of databases, surveys, studies, foundation models, techniques and methodologies (either uni-modal or multi-modal; uni-task or multi-task ones) are solicited on -but are not limited to- the following topics:

i) facial expression (basic, compound or other) or micro-expression analysis
ii) facial action unit detection
iii) valence-arousal estimation
iv) physiological-based (e.g.,EEG, EDA) affect analysis
v) face recognition, detection or tracking
vi) body recognition, detection or tracking
vii) gesture recognition or detection
viii) pose estimation or tracking
ix) activity recognition or tracking
x) lip reading and voice understanding
xi) face and body characterization (e.g., behavioral understanding)
xii) characteristic analysis (e.g., gait, age, gender, ethnicity recognition)
xiii) group understanding via social cues (e.g., kinship, non-blood relationships, personality)
xiv) video, action and event understanding
xv) digital human modeling
xvi) characteristic analysis (e.g., gait, age, gender, ethnicity recognition)
xvii) violence detection
xviii) autonomous driving
xix) domain adaptation, domain generalisation, few- or zero-shot learning for the above cases
xx) fairness, explainability, interpretability, trustworthiness, privacy-awareness, bias mitigation and/or subgroup distribution shift analysis for the above cases
xxi) editing, manipulation, image-to-image translation, style mixing, interpolation, inversion and semantic diffusion for all afore mentioned cases



Accepted workshop papers will appear at ICCV 2025 proceedings.
