A new technology called Facial Emotion Recognition (FER) tries to replicate exactly the decoding phase of the emotion from the facial expression by exploiting the state of the art AI techniques. The technique needs, in order to be performed, to leverage on a dataset of facial expression previously annotated in such a way to have a ground truth. The dataset itself was built in a collaboration between the Politecnico di Torino and the Pontifıcia Universidade Catolica do Rio de Janeiro, in order to create a dataset of Brazilian faces. The data were collected by showing to volunteers 48 emotional images, in random order, selected from the IAPS and GAPED databases.
