A Multi-cut Formulation for Joint Segmentation and Tracking of Multiple Objects

Keuper, Margret, Tang, Siyu, Zhongjie, Yu et al.

Understand

Recently, Minimum Cost Multicut Formulations have been proposed and proven to be successful in both motion trajectory segmentation and multi-target tracking scenarios.

  • Both tasks benefit from decomposing a graphical model into an optimal number of connected components based on attractive and repulsive pairwise terms.
  • The two tasks are formulated on different levels of granularity and, accordingly, leverage mostly local information for motion segmentation and mostly high-level information for multi-target tracking.
  • In this paper we argue that point trajectories and their local relationships can contribute to the high-level task of multi-target tracking and also argue that high-level cues from object detection and tracking are helpful to solve motion segmentation.
