# Attention-guided Context Feature Pyramid Network for Object Detection

This repository is written by Junxu Cao, on the base of [Detectron](https://github.com/facebookresearch/Detectron) @ [e8942c8](https://github.com/facebookresearch/Detectron/tree/e8942c882abf6e28fe68a626ec55028c9bdfe1cf).

## Introduction

This repository re-implements AC-FPN on the base of [Detectron](https://github.com/facebookresearch/Detectron) and [Detectron-Cascade-RCNN](https://github.com/zhaoweicai/Detectron-Cascade-RCNN).

Please follow [Detectron](https://github.com/facebookresearch/Detectron) on how to install and use Detectron-Cascade-RCNN.

Because of the proposed architecture, We have better performance on most of FPN-base methods, especially on large objects.
