A Database of Non-Manual Signs in Turkish Sign Language

Sign languages are visual languages. The message is not only transferred via hand gestures (manual signs) but also head/body motion and facial expressions (non-manual signs). In this article, we present a database of non-manual signs in Turkish sign language (TSL). There are eight non-manual signs in the database, which are frequently used in TSL. The database contains the videos of these signs as well as a ground truth data of 60 manually landmarked points of the face.
