R-FCN:Object Detection via Region-based Fully Convolutional Network

Abstract

  1. Region-based & Fully Convolution network
  2. Position-sensitive score maps

Introduction

  1. RoI pooling layer & RoI-wise subnetwork
  2. Deeper RoI-wise subnetwork cost lot, lower speed due to unshared per-RoI computation
  3. translation invariance & translation variance
  4. score maps encodes the position information, position-sensitive RoI pooling layer shepherds information
  5. Backbone 101-layer Residual Net
