PAA for Faster RCNN

In this repo, you can train Faster RCNN with PAA (applied to RPN):

python tools/train_net.py \
	--config-file configs/COCO-Detection/faster_rcnn_R_50_FPN_iou_paa_1x.yaml

Reults:

Model	AP (minival)	AP50	AP75	APs	APm	APl
Faster_R_50_FPN_1x	37.989	58.810	41.314	22.361	41.522	49.584
Faster_R_50_FPN_PAA_1x	39.292	60.019	42.567	22.650	43.170	51.875

Note

This repo is based on an old version of Detectron2, so the implementation of PAA is not compatible with the latest Detecton2.

Detectron2 is Facebook AI Research's next generation software system that implements state-of-the-art object detection algorithms. It is a ground-up rewrite of the previous version, Detectron, and it originates from maskrcnn-benchmark.

What's New

• It is powered by the PyTorch deep learning framework.
• Includes more features such as panoptic segmentation, densepose, Cascade R-CNN, rotated bounding boxes, etc.
• Can be used as a library to support different projects on top of it. We'll open source more research projects in this way.
• It trains much faster.

See our blog post to see more demos and learn about detectron2.

Installation

See INSTALL.md.

Quick Start

See GETTING_STARTED.md, or the Colab Notebook.

Learn more at our documentation. And see projects/ for some projects that are built on top of detectron2.

Model Zoo and Baselines

We provide a large set of baseline results and trained models available for download in the Detectron2 Model Zoo.
