Zero-Shot Detection

Zhu, Pengkai, Wang, Hanxiao, Saligrama, Venkatesh

Understand

As we move towards large-scale object detection, it is unrealistic to expect annotated training data, in the form of bounding box annotations around objects, for all object classes at sufficient scale, and so methods capable of unseen object detection are required.

  • We propose a novel zero-shot method based on training an end-to-end model that fuses semantic attribute prediction with visual features to propose object bounding boxes for seen and unseen classes.
  • While we utilize semantic features during training, our method is agnostic to semantic information for unseen classes at test-time.
  • Our method retains the efficiency and effectiveness of YOLOv2 for objects seen during training, while improving its performance for novel and unseen objects.
