What does the face_gaze mean in the annotation file? It does not the left/right eye gaze or the mean of the both eyes gaze, right? Which 3d landmark do you use to calculate the face gaze?

Hi,

The face_gaze means the gaze direction of the face image. It is centered on the face. The 3D landmarks are described in the paper. It is fitted 3D face model to the 2D detected landmarks.
