Abstract:
Boundary prediction in images as well as video has been a very active topic
of research and organizing visual information into boundaries and segments is
believed to be a corner stone of visual perception. While prior work has
focused on predicting boundaries for observed frames, our work aims at
predicting boundaries of future unobserved frames. This requires our model to
learn about the fate of boundaries and extrapolate motion patterns. We
experiment on established real-world video segmentation dataset, which provides
a testbed for this new task. We show for the first time spatio-temporal
boundary extrapolation in this challenging scenario. Furthermore, we show
long-term prediction of boundaries in situations where the motion is governed
by the laws of physics. We successfully predict boundaries in a billiard
scenario without any assumptions of a strong parametric model or any object
notion. We argue that our model has with minimalistic model assumptions derived
a notion of 'intuitive physics' that can be applied to novel scenes.
