Should I remove faces in 90°?
I have done an extraction and I have sorted with the app tool, when I going to verify data and later check and delete no faces images I found faces in 90°, 180° and others when face apear but the middle part of body too, so the question is should I delete all this faces and only keep faces when the face appear in 0° and just the face without body? or some images with middle body part or rotated faces could be used too?
