title: OBJECT DYNAMICS DISTILLATION FOR SCENE DECOMPOSITION AND REPRESENTATION
abstract: The ability to perceive scenes in terms of abstract entities is crucial for us to
  achieve higher-level intelligence. Recently, several methods have been proposed
  to learn object-centric representations of scenes with multiple objects, yet most
  of which focus on static scenes. In this paper, we work on object dynamics and
  propose Object Dynamics Distillation Network (ODDN), a framework that distillates explicit object dynamics (e.g., velocity) from sequential static representations. ODDN also builds a relation module to model object interactions. We verify
  our approach on tasks of video reasoning and video prediction, which are two important evaluations for video understanding. The results show that the reasoning
  model with visual representations of ODDN performs better in answering reasoning questions around physical events in a video compared to the previous state-of-the-art methods. The distilled object dynamics also could be used to predict
  future video frames given two input frames, involving occlusion and objects collision. In addition, our architecture brings better segmentation quality and higher
  reconstruction accuracy.
