Towards Grand Unification of Object Tracking. (arXiv:2207.07078v4 [cs.CV] UPDATED)

We present a unified method, termed Unicorn, that can simultaneously solve
four tracking problems (SOT, MOT, VOS, MOTS) with a single network using the
same model parameters. Due to the fragmented definitions of the object tracking
problem itself, most existing trackers are developed to address a single or
part of tasks and overspecialize on the characteristics of specific tasks. By
contrast, Unicorn provides a unified solution, adopting the same input,
backbone, embedding, and head across all tracking tasks. For the …
