DAFNe: A One-Stage Anchor-Free Approach for Oriented Object Detection

Code for our Paper DAFNe: A One-Stage Anchor-Free Approach for Oriented Object Detection.

Datasets

• UCAS-AOD: https://hyper.ai/datasets/5419
• DOTA 1.0/1.5: https://captain-whu.github.io/DOTA/index.html
  • Note: See ./tools/prepare_dota/ for instructions on how to prepare the DOTA datasets.
• HRSC2016: https://www.kaggle.com/guofeng/hrsc2016

Docker Setup

Use the Dockerfile to build the necessary docker image:

docker build -t dafne .

Training

Check out ./configs/pre-trained/ for different pre-defined configurations for the DOTA 1.0, DOTA 1.5, UCAS-AOD, and HRSC2016 datasets. Use these paths as argument for the --config-file option below.

With Docker

Use the ./tools/run.py helper to start running experiments

./tools/run.py --gpus 0,1,2,3 --config-file ./configs/dota-1.0/1024.yaml

Without Docker

NVIDIA_VISIBLE_DEVICES=0,1,2,3 ./tools/plain_train_net.py --num-gpus 4 --config-file ./configs/dota-1.0/1024.yaml

Pre-Trained Weights

Dataset	mAP (%)	Config	Weights
UCAS-AOD	89.65	ucas_aod_r101_ms	ucas-aod-r101-ms.pth
HRSC2016	89.76	hrsc_r50_ms	hrsc-r50-ms.pth
DOTA 1.0	76.95	dota-1.0_r101_ms	dota-1.0-r101-ms.pth
DOTA 1.5	71.99	dota-1.5_r101_ms	dota-1.5-r101-ms.pth

Pre-Trained Weights Usage with Docker

./tools/run.py --gpus 0 --config-file <CONFIG_PATH> --opts "MODEL.WEIGHTS <WEIGHTS_PATH>"

Pre-Trained Weights Usage without Docker

NVIDIA_VISIBLE_DEVICES=0 ./tools/plain_train_net.py --num-gpus 1 --config-file <CONFIG_PATH> MODEL.WEIGHTS <WEIGHTS_PATH>
