Contents
• Introduction
• Feature Pyramid Networks
• Experiments on Object Dectection
Introduction
Multi-scale feature
representation
Hierarchy network
Feature
Pyramid
Networks
Bottom-up pathway
=> ConvNet ,
Define pyramid level
Top-down pathway
=> upsampling
Application
• Feature Pyramid Networks for RPN
- single scale feature map => FPN
- use shared parameter
• Feature Pyramid Networks for Fast-RCNN
Experiments on Object Dectection
• Region Proposal with RPN
Experiments on Object Dectection
• Fast/Faster R-CNN
• 감사합니다
