All in Tokens: Unifying Output Space of Visual Tasks via Soft Token

Ning, Jia, Li, Chen, Zhang, Zheng et al.

Understand

Unlike language tasks, where the output space is usually limited to a set of tokens, the output space of visual tasks is more complicated, making it difficult to build a unified visual model for various visual tasks.

  • In this paper, we seek to unify the output space of visual tasks, so that we can also build a unified model for visual tasks.
  • To this end, we demonstrate a single unified model that simultaneously handles two typical visual tasks of instance segmentation and depth estimation, which have discrete/fixed-length and continuous/varied-length outputs, respectively.
  • We propose several new techniques that take into account the particularity of visual tasks: 1) Soft token.
