(EN) USING DISC TO EVALUATE THE EMOTIONAL RESPONSE OF AN INDIVIDUAL
(FR) UTILISATION DE LA TECHNIQUE DISC POUR ÉVALUER LA RÉPONSE ÉMOTIONNELLE D'UNE PERSONNE
Abstract
(EN)
The present invention comprises the use of Digital Image Speckle Correlation (DISC) to map facial deformations due to voluntary and/or involuntary, often sutable, facial expressions. The techniques of the present invention can be used to extend and improve to use test subject feedback to correlate facial expression to human emotion. The present invention utilizes a camera (1) to capture a facial image. Data collected by the camera is pre-processedby a frame grabber (2), and the digitized information is downloaded to a computer (3) for numerical analysis.
(FR)
L'invention consiste à utiliser la technique de Corrélation de la Granularité d'Images Numériques (DISC) pour cartographier des déformations faciales dues à des expressions faciales volontaires et/ou involontaires souvent subtiles. Les expressions faciales peuvent résulter d'une réponse à des stimuli internes ou externes. Il est alors possible d'établir des caractérisations quantitatives et qualitatives de la réponse d'une personne. Les techniques de l'invention peuvent être utilisées pour développer et améliorer le système de codage FACS, lequel consiste à affecter des émotions humaines à des expressions faciales. Il est également possible d'utiliser les réactions de sujets témoins pour corréler des expressions faciales à des émotions humaines.
