UIBVFED
UIBVFED[1] is the first database comprising synthetic avatars that categorizes up to 32 facial expressions. The dataset is composed of 660 facial images (1080 x 1920) from 20 virtual characters, each creating 32 facial expressions. The avatars represent 10 men and 10 women, aged between 20 and 80, from different ethnicities. Expressions are classified based on the six universal emotions (Anger, Disgust, Fear, Joy, Sadness, and Surprise) according to Faigin’s classification[2], whose work is considered the standard to follow by animators and 3D artists. In addition to Faigin’s expression classification, the database provides the equivalence of the Facial Action Coding System (FACS)[3] with information about the position of the 51 facial landmarks in the 3D space to facilitate expression recognition. This is because the images of the facial expressions in the dataset were generated following the FACS guidelines. Therefore, the deformations that were applied to the 3D models have a direct correspondence with the Action Units (AUs) that are associated with each expression. This procedure ensures an objective labelling of all the images. Information about the landmarks for all characters and expressions is included in the dataset.
Figure 1 shows the 32 expressions plus the neutral one of one of the 20 characters in the UIBVFED database and their associated emotion.
The dataset is provided together with an interactive application, the UIBVFED application GUI, that allows users to activate and control the expression intensity of the characters from different points of view.
