Hi,

I was struggling to get a good face detection for an actress lying down on a bed.

So I rotated the image 90 degrees before the Face Extract, and Bob’s Your Uncle, it detected it perfectly.

Invert you transform downstream of the matte and it all comes together

Enjoy

Great tip! The ML tools are finicky like that. The more you use them, the more you understand what they are looking for and how to get the most out of them.

Trying some face det this morning, is there a way to feed in constraining gmasks? (the actor’s hand goes across his face)
