Recognition of six facial expressions, as well as eye blinking, on a large set of image sequences is reported. Research in psychology has indicated that at least six emotions are universally associated with distinct facial expressions. Several other emotions, and many combinations of emotions, have been studied but remain unconfirmed as universally distinguishable. Few studies have directly investigated the influence of the motion and deformation of facial features on the interpretation of facial expressions. By using improved cortical filters, we currently achieve a recognition rate of 98.5 on a database of 205 images of 30 persons.
Regulators are non verbal mediators such as nods and smiles.
Our interest focuses here on recognizing emotions conveyed by human faces. We focus our attention on the appearance of the face from its near frontal image projection, without considering the underlying anatomic and musculature models and actions. No context found.
