v1.8.0

Video face detection is more accurate: it now analyzes video at the full
detection resolution, so it catches faces it used to miss and stops covering
signage it mistook for a face.

Improvements

• The fast face model now analyzes video at the full detection resolution
  instead of a third of it, so smaller and partly turned faces that used to
  slip through are covered
• Fewer false masks: a logo or sign that briefly resembles a face no longer
  stays covered for the rest of the shot
• Masks follow faces more faithfully — they no longer glide into place a few
  frames early, and stay on a face through brief detection dropouts

Details

• The bundled fast model ships with a fixed 640 px input; it is now adapted in
  memory at load time to run at the requested video resolution, with a probe
  check and automatic fallback to its native size, or to the CPU, if a GPU
  backend can't run it
• A track needs several confident detections to be kept, so sparse false
  positives are dropped — while a short but clearly detected face is still
  covered
• A track that goes too long without a confident detection ends instead of
  coasting indefinitely, and moving faces get more leeway than static signage
