Hierarchical Object Detection with Deep Reinforcement Learning

hoddr

  1. Hierarchically propose object regions
  2. Do not share conv computation by RoI pooling
  3. Use direct proposals on the input image
  4. Conv sharing reduces the performance sue to spatial information loss (their claim)
  5. They do not give extensive experimentation !
  6. Given visual examples are simple without any clutter background !
  7. Still using Reinforcement Learning seems curious.
