Vrsumo2017
Vrsumo2017 I notice it differs from video to video, I found one scene with a white room and it didn't work as well as other white rooms I've tried, must be something the camera and lighting too I guess.
Problem with white is, that that her eyes become transparent with the pupils floating in the air, same with teeth when she opens her mouth.
You probably could combine it with face detection and use it to exclude some parts from the keying.
Another thing is also that it is hard to avoid spilling, and if you wanna change the background to something opposite it becomes pretty obvious.
For example if you are in a well lit room and remove the dark background, you likely get a dark outline around the model making it almost look like a cartoon, and vice versa if you are in a dimly lit room and the remove bright light from the scene, you get a bright outline, although I guess this is less noticeable, and well you could maybe adjust your room light according to the scene.
