Improving CodeFormer videos

Hello Selur,

  I noted that there are situations where the "retinaface" detector is introducing strong artifacts.

  You can find an example here:
  https://imgsli.com/MjM5MDQz

  the only combination with no artifacts (for the sample used) are
 
  CF Detector: dlib
  CF Detector: retinaface with only center

  The second detector has the disadvantage to not enhance the faces that are in background.

  You can find an example here:

  https://imgsli.com/MjM5MDQ2
     
  In this case "retinaface (only center)" is worse than "dlib"

  The big problem is that "dlib" is very very very slow (speed 0.005 fps).
  Do you know if the version available in Hybrid is CUDA enabled ? because I checked the flag dlib.DLIB_USE_CUDA and it is False.

Thanks,
Dan

P.S.
I attached a sample that when encoded with CF shows the artifacts
