landmark stability on video frames

[NikoBele1]

Hi, is there a way to stabilize the landmarks for subsequent video frames? The landmarks move quite a bit, even when there is no face movement in the video. They "jump around" by ~10 pixel.
Where does this behavior come from?

Some of it its down to the native 64x64px resolution in the output space (in practice the effective one is closer to 40x40px). In can address this with some smoothing filtering, careful initialization etc. The results in the demo gif are based on some careful, frame by frame re-initialisation
