I would like to know if it is possible to recognize the teeth in face tracking
Thanks for the question.
What is it you are trying to achieve?
Are you trying to attach something to the mouth so it seems as though there are teeth?
This could be done by adding a 3D model or a plane over the mouth center attachment point, although, it will not wrap to the teeth, just overlay them.
Are you trying to cause an event to happen when the teeth are shown?
If so, this can be done by utilising the mouth open event.
Hope this helps.
I wonder if there is any tracking in the teeth, because I would like to overlap your teeth with new teeth, is it possible?
