Automated face analysis by feature point tracking has high concurrent validity with manual FACS coding.
The face is a rich source of information about human behavior. Available methods for coding facial displays, however, are human-observer dependent, labor intensive, and difficult to standardize. To enable rigorous and efficient quantitative measurement of facial displays, we have developed an automated method of facial display analysis. In this report, we compare the results with this automated...
متن کاملBeyond Prototypic Expressions: Discriminating Subtle Changes in the Face
Current approaches to automated analysis have focused on a small set of prototypic expressions (e.g., joy or anger). Prototypic expressions occur infrequently in everyday life, however, and emotion expression is far more varied. To capture the full range of emotion expression, automated discrimination of fine-grained changes in facial expression is needed. We developed and implemented a compute...
متن کاملFast-FACS: A Computer-Assisted System to Increase Speed and Reliability of Manual FACS Coding
FACS (Facial Action Coding System) coding is the state of the art in manual measurement of facial actions. FACS coding, however, is labor intensive and difficult to standardize. A goal of automated FACS coding is to eliminate the need for manual coding and realize automatic recognition and analysis of facial actions. Success of this effort depends in part on access to reliably coded corpora; ho...

متن کاملActive Face and Feature Tracking
This paper describes a method for the detection and tracking of human face and facial features. Skin segmentation is learnt from samples of an image. After detecting a moving object , the corresponding area is searched for clusters of pixels with a known distribution. Since we only use the hue (color) component this process is quite insensitive to illumination changes. The face localization pro...
