In this work we present methods for automatic estimation of non-manual gestures in sign language videos. More specifically, we
study the estimation of three head pose angles (yaw, pitch, roll) and the state of facial elements (eyebrow position, eye openness, and
mouth state). This kind of estimation facilitates automatic annotation of sign language videos and promotes more prolific production
of annotated sign language corpora. The proposed estimation methods are incorporated in our publicly available SLMotion software
package for sign language video processing and analysis. Our method implements a model-based approach: for head pose we employ
facial landmarks and skins masks as features, and estimate yaw and pitch angles by regression and roll using a geometric measure; for
the state of facial elements we use the geometric information of facial elements of the face as features, and estimate quantized states
using a classification algorithm. We evaluate the results of our proposed methods in quantitative and qualitative experiments.
