“…The third ABAW Competition, to be held in conjunction with the IEEE International Conference on Computer Vision and Pattern Recognition (CVPR), 2022 is a continuation of the first [24] and second [32] ABAW Competitions held in conjunction with the IEEE Conference on Face and Gesture Recognition (IEEE FG) 2021 and with the International Conference on Computer Vision (ICCV) 2022, respectively, which targeted dimensional (in terms of valence and arousal) [2][3][4]8,9,11,21,35,39,47,48,50,[54][55][56], categorical (in terms of the basic expressions) [12,15,16,33,36,37,51] and facial action unit analysis and recognition [7,19,20,25,26,40,44,47]. The third ABAW Competition contains four Challenges, which are based on the same in-the-wild database, (i) the uni-task Valence-Arousal Estimation Challenge; (ii) the uni-task Expression Classification Challenge (for the 6 basic expressions plus the neutral state plus the 'other' category that denotes expressions/affective states other than the 6 basic ones); (iii) the uni-task Action Unit Detection Challenge (for 12 action units); (iv) the Multi-Task Learning Challenge (for joint learning and predicting of valence-arousal, 8 expressions -6 basic plus neutral plus 'other'-and 12 action units).…”
