Pretty sure it's a machine learning model for video segmentation. It doesn't guess the foreground by motion: it guess it with millions of human-annotated masks.

Deep learning is making decades of research obsolete by delivering better results with more generalisation and less time.

Different techniques don't mean it isn't still natural image matting. I was guessing to give people a starting point on what to look at. Does it reference a paper somewhere? Just saying 'deep learning's doesn't really explain much.
