Understand

This paper presents a Generative RegIon-to-Text transformer, GRiT, for object understanding.

  • The spirit of GRiT is to formulate object understanding as <region, text> pairs, where region locates objects and text describes objects.
  • For example, the text in object detection denotes class names while that in dense captioning refers to descriptive sentences.
  • Specifically, GRiT consists of a visual encoder to extract image features, a foreground object extractor to localize objects, and a text decoder to generate open-set object descriptions.
