Although facial features are considered to be essential for humans to understand sign language, no prior research work has yet examined their significance for automatic sign language recognition or presented some evaluation results. This paper describes a vision-based recognition system that employs both manual and facial features, extracted from the same input image. For facial feature extraction an active appearance model is applied to identify areas of interest such as the eyes and mouth… CONTINUE READING
