Learning to Discover Multi-Class Attentional Regions for Multi-Label Image Recognition

Gao, Bin-Bin, Zhou, Hong-Yu

Understand

Multi-label image recognition is a practical and challenging task compared to single-label image classification.

  • However, previous works may be suboptimal because of a great number of object proposals or complex attentional region generation modules.
  • In this paper, we propose a simple but efficient two-stream framework to recognize multi-category objects from global image to local regions, similar to how human beings perceive objects.
  • To bridge the gap between global and local streams, we propose a multi-class attentional region module which aims to make the number of attentional regions as small as possible and keep the diversity of these regions as high as possible.
