Because of an experiment, I need to know the following four characteristics ：1）head rotation about the x-axis (pitch);2）head rotation about the z-axis (roll);3）the 3-D horizontal distance between the corners of themouth (mouthh);4）the 3-D vertical distance between the lower and upper lip (mouthv).
I want to know which features are related to them . THX.

how did you go about invoking openface from python or command line? Thanks

@kendrew06 @paulSerre i obtained this values (namely gaze_angle, pose_T and so on) but how can i use them to understand if looking right, left, down or up? What are the intervals to determine if person looks right, left, up or down?

TadasBaltrusaitis commented 3 years ago

The gaze angle is in radians (you can convert it to degrees to make it more intuitive). The definition of someone looking up or down will vary somewhat on your use case and I suggest you try visualizing your data to determine appropriate thresholds.
