Portrait orientation possible?

[migri1024]

Hi,
I really appreciate the work being shared in this project!
One question I am struggeling with:

Is ist possible to extend the software in order to get it running in portrait orientation also? So far I get detections in landscape orientation. But as soon as I change to portrait, the overlay disappears and no more head detection or head pose estimation is displayed.

Please, if someone could help. I am quite lost (and I am a beginner...)
Thanx.
