FCOS for Object Detection

Introduction

FCOS (Fully Convolutional One-Stage Object Detection) is a fast anchor-free object detection framework with strong performance. We reproduced the model of the paper, and improved and optimized the accuracy of the FCOS.

Highlights:

• Training Time: The training time of the model of fcos_r50_fpn_1x on Tesla v100 with 8 GPU is only 8.5 hours.
