Facial Feature Tracking and Occlusion Recovery in American Sign Language

2006 6th International Workshop on Pattern Recognition in Information Systems   unpublished
Facial features play an important role in expressing grammatical information in signed languages, including American Sign Language (ASL).  ...  Therefore, identification of these facial gestures is essential to sign language recognition. One problem with detection of such grammatical indicators is occlusion recovery.  ...  We would like to thank Stan Sclaroff and Vassilis Athitsos for helping to collect the ASL videos.  ...
