Abstract:
Facial Expression Recognition has gained considerable attention in the field of affective computing, but only a few works considered the intensity of emotion embedded in the expression. Even the available studies on expression intensity estimation successfully assigned a nominal/regression value or classified emotion in a range of intervals. The approaches from multiclass and its extensions do not conform to man heuristic manner of recognising emotion with the respective intensity. This work is presenting a Multi-label CNN-based model that could simultaneously recognise emotion and also provide ordinal metrics as the intensity of the emotion. In the experiments conducted on BU-3DFE and Cohn Kanade (CK+) datasets, we check how well our model could adapt and generalise. Our model gives promising results with multilabel evaluation metrics and generalises well when trained on BU-3DFE and evaluated on CK+.
