Does it benefit the model to have "faces" extracted from behind the face? I'm talking about pictures where you would be able to see the edges of the chin and the nose protruding next to the cheek. Is this information usefull, or won't it be considered when swapping faces?
Also, I get that pictures where the whole face is visible are good because there is information about the whole structure, but pictures with a little zoom are good too because then the extracted face will have more detail. At least I remember reading about it. If so, would it be a good idea to have the same picture twice, one with a little zoom and one without?
