6th Workshop and Competition on


Affective Behavior Analysis in-the-wild (ABAW)

in conjunction with the IEEE Computer Vision and Pattern Recognition Conference (CVPR), 2024

18 June 2024

About ABAW

The ABAW Workshop and Competition has a unique aspect of fostering cross-pollination of different disciplines, bringing together experts (from academia, industry, and government) and researchers of mobile and ubiquitous computing, computer vision and pattern recognition, artificial intelligence and machine learning, multimedia, robotics, HCI, ambient intelligence and psychology. The diversity of human behavior, the richness of multi-modal data that arises from its analysis, and the multitude of applications that demand rapid progress in this area ensure that our events provide a timely and relevant discussion and dissemination platform.

The ABAW Workshop and Competition is a continuation of the respective Workshops and Competitions held at IEEE CVPR 2023, ECCV 2022, IEEE CVPR 2022, ICCV 2021, IEEE FG 2020 (a), IEEE FG 2020 (B) and IEEE CVPR 2017 Conferences.

The Workshop



Call for Papers

This Workshop will solicit contributions on the recent progress of recognition, analysis, generation-synthesis and modelling of face, body, gesture, speech, audio, text and language while embracing the most advanced systems available for such in-the-wild (i.e., in unconstrained environments) analysis, and across modalities like face to voice. In parallel, this Workshop will solicit contributions towards building fair, explainable, trustworthy and privacy-aware models that perform well on all subgroups and improve in-the-wild generalisation.

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:

    facial expression (basic, compound or other) or micro-expression analysis

    facial action unit detection

Valence-Arousal (VA) Estimation Challenge

Database

For this Challenge, an augmented version of the Aff-Wild2 database will be used. This database is audiovisual (A/V), in-the-wild and in total consists of 594 videos of around 3M frames of 584 subjects annotated in terms of valence and arousal.

Rules

Only uni-task solutions will be accepted for this Challenge; this means that the teams should only develop uni-task (valence-arousal estimation task) solutions. Teams are allowed to use any -publicly or not- available pre-trained model (as long as it has not been pre-trained on Aff-Wild2). The pre-trained model can be pre-trained on any task (e.g., VA estimation, Expression Recognition, AU detection, Face Recognition). However when the teams are refining the model and developing the methodology they should not use any other annotations (expressions or AUs): the methodology should be purely uni-task, using only the VA annotations. This means that teams are allowed to use other databases' VA annotations, or generated/synthetic data, or any affine transformations, or in general data augmentation techniques (e.g., MixAugment) for increasing the size of the training dataset.

Performance Assessment

The performance measure (P) is the mean Concordance Correlation Coefficient (CCC) of valence and arousal:

CCCarousal + CCCvalence
2

Baseline Results

The baseline network is a pre-trained on ImageNet ResNet-50 and its performance on the validation set is:

CCCvalence = 0.24,     CCCarousal = 0.20

P = 0.22

Expression (Expr) Recognition Challenge

Database

For this Challenge, the Aff-Wild2 database will be used. This database is audiovisual (A/V), in-the-wild and in total consists of 548 videos of around 2.7M frames that are annotated in terms of the 6 basic expressions (i.e., anger, disgust, fear, happiness, sadness, surprise), plus the neutral state, plus a category 'other' that denotes expressions/affective states other than the 6 basic ones.

Rules

Only uni-task solutions will be accepted for this Challenge; this means that the teams should only develop uni-task (expression recognition task) solutions. Teams are allowed to use any -publicly or not- available pre-trained model (as long as it has not been pre-trained on Aff-Wild2). The pre-trained model can be pre-trained on any task (e.g., VA estimation, Expression Recognition, AU detection, Face Recognition). However when the teams are refining the model and developing the methodology you should not use any other annotations (VA or AUs): the methodology should be purely uni-task, using only the Expr annotations. This means that teams are allowed to use other databases' Expr annotations, or generated/synthetic data (e.g. the data provided in the ECCV 2022 run of the ABAW Challenge), or any affine transformations, or in general data augmentation techniques (e.g., MixAugment) for increasing the size of the training dataset.

Performance Assessment

The performance measure (P) is the average F1 Score across all 8 categories:   ∑ F1/8

Baseline Results

The baseline network is a pre-trained VGGFACE (with fixed convolutional weights and with MixAugment data augmentation technique) and its performance on the validation set is:

P = 0.25

Action Unit (AU) Detection Challenge

Database

For this Challenge, the Aff-Wild2 database will be used. This database is audiovisual (A/V), in-the-wild and in total consists of 547 videos of around 2.7M frames that are annotated in terms of 12 action units, namely AU1,AU2,AU4,AU6,AU7,AU10,AU12,AU15,AU23,AU24,AU25,AU26.

Rules

Only uni-task solutions will be accepted for this Challenge; this means that the teams should only develop uni-task (action unit detection task) solutions. Teams are allowed to use any -publicly or not- available pre-trained model (as long as it has not been pre-trained on Aff-Wild2). The pre-trained model can be pre-trained on any task (e.g., VA estimation, Expression Classification, AU detection, Face Recognition). However when the teams are refining the model and developing the methodology you should not use any other annotations (VA or Expr): the methodology should be purely uni-task, using only the AU annotations. This means that teams are allowed to use other databases' AU annotations, or generated/synthetic data, or any affine transformations, or in general data augmentation techniques (e.g., MixAugment) for increasing the size of the training dataset.

Performance Assessment

The performance measure (P) is the average F1 Score across all 12 categories:   ∑ F1/12

Baseline Results

The baseline network is a pre-trained VGGFACE (with fixed convolutional weights) and its performance on the validation set is:

P = 0.39

Compound Expression (CE) Recognition Challenge

Database

For this Challenge, a part of C-EXPR-DB database will be used (56 videos in total). C-EXPR-DB is audiovisual (A/V) in-the-wild database and in total consists of 400 videos of around 200K frames; each frame is annotated in terms of 12 compound expressions. For this Challenge, the following 7 compound expressions will be considered: Fearfully Surprised, Happily Surprised, Sadly Surprised, Disgustedly Surprised, Angrily Surprised, Sadly Fearful and Sadly Angry.

Goal of the Challenge and Rules

Participants will be provided with a part of C-EXPR-DB database (56 videos in total), which will be unannotated, and will be required to develop their methodologies (supervised/self-supervised, domain adaptation, zero-/few-shot learning etc) for recognising the 7 compound expressions in this unannotated part, in a per-frame basis.

Teams are allowed to use any -publicly or not- available pre-trained model and any -publicly or not- available database (that contains any annotations, e.g. VA, basic or compound expressions, AUs)

Performance Assessment

The performance measure (P) is the average F1 Score across all 7 categories:   ∑ F1/7

Emotional Mimicry Intensity (EMI) Estimation Challenge

Database

For this Challenge, the multimodal Hume-Vidmimic2 dataset is used which consists of more than 15,000 videos totaling over 25 hours. In this dataset, every participant was tasked with imitating a 'seed' video that showcased an individual displaying a particular emotion. Following the mimicry, they were then asked to assess the emotional intensity of the seed video by selecting from a range of predefined emotional categories. The following emotion dimensions are targeted: 'Admiration', 'Amusement', 'Determination', 'Empathic Pain', 'Excitement', and 'Joy'. A normalized score from 0 to 1 is provided as a ground truth value.

Performance Assessment

The performance measure is the average Pearson's correlation (ρ) across the 6 emotion dimensions:   ∑ ρ/6

Baseline Results

We established baseline results using two different feature sets.

First, we employed pre-trained Vision Transformer (ViT) features, which were further processed through a three-layer Gated Recurrent Unit (GRU) network. This approach achieved a performance score of: 0.09.

Secondly, we utilized features extracted from Wav2Vec2, combined with a linear processing layer, which resulted in a performance score of: 0.24.

Additionally, we explored a multimodal approach by averaging the predictions from both unimodal methods, leading to a combined performance score of: 0.25.
