Overview

Frequency Spectrum Augmentation Consistency for Domain Adaptive Object Detection

Main requirements

torch >= 1.0

torchvision >= 0.2.0

Python 3

Environmental settings

This repository is developed using python 3.6.12 on Ubuntu 16.04.5 LTS. The CUDA and pytorch version is 11.2 and 1.7.1. We use one NVIDIA 3090 GPU card for training and testing.

Dataset

PASCAL VOC, Watercolor, Cityscapes, Foggycityscapes -> Please follow the instructions in [Link] to prepare the datasets.

Daytime-Sunny, Dusk-Rainy, and Night-Rainy -> Dataset preparation instruction link [Link].

Code

Faster R-CNN -> Thanks for jwyang [Link]; Fourier Domain Adaptation -> Thanks for Yanchao Yang [Link].

Our Augmentation (Mix+Replace+Extend+Disorder).

Train

To train a faster R-CNN model with vgg16 on pascal_voc:

CUDA_VISIBLE_DEVICES=$GPU_ID python trainval_net.py --dataset pascal_voc --net vgg16 --bs 1 --cuda

And you need to add augmentated data in the loadpath by creating a new dataset_name variable.

Test

To test:

python test_net.py --dataset pascal_voc --net vgg16 --modelpath your modelpath --cuda

Augmentation

Daytime-Sunny -> Dusk-Rainy shapenet_illuminants

Daytime-Sunny -> Night-Rainy shapenet_illuminants

Result

shapenet_illuminants

Results on adaptation from Cityscapes to FoggyCityscapes. ‘prsn’, ‘mcycl’, and ‘bcycl’ separately denote ‘person’, ‘motorcycle’, and ‘bicycle’ category.

shapenet_illuminants

Results on adaptation from Daytime-sunny to Duskrainy. Here, we directly run the released codes of the compared methods to obtain the results.

shapenet_illuminants

Results on Daytime-sunny → Night-rainy.

shapenet_illuminants

Results on the compound target domain.
