Quantification of Cinematography Semiotics for Video-based Facial Emotion Recognition in the EmotiW 2015 Grand Challenge
Albert C. Cruz · 2015
The Emotion Recognition in the Wild challenge poses significant problems to state of the art auditory and visual affect quantification systems. To overcome the challenges, we investigate supplementary meta features based on film semiotics. Movie scenes are often presented and arranged in such a way as to amplify the emotion interpreted by the viewing audience. This technique is referred to as mise en scene in the film industry and involves strict and intentional control of color palette, light source color, and arrangement of actors and objects in the scene. To this end, two algorithms for extracting mise en scene information are proposed. Rule of thirds based motion history histograms detect motion along rule of thirds guidelines. Rule of thirds color layout descriptors compactly describe a scene at rule of thirds intersections. A comprehensive system is proposed that measures expression, emotion, vocalics, syntax, semantics, and film-based meta information. The proposed mise en scene features have a higher classification rate and ROC area than LBP-TOP features on the validation set of the EmotiW 2015 challenge. The complete system improves classification performance over the baseline algorithm by 3.17% on the testing set.
