Redefine model can change the face beyond to be recognition.
The idea came to my mind is that instead of the whole photo, the faces could be indicated so that only they would be changed.
Why?
For the purposes of publishing photos, while maintaining the privacy of people who have not expressed this permission. In my work, we must especially take care of so that the faces of the children are not visible, which strongly limits us the ability to compose photos.
If Topaz made a model changing only faces, we will have more flexibility.
