Installation

Please refer to low-light-object-detection-detectron2 for installation requirements

Datasets

ExDark

Create a new folder named "exdark" in the "low-light-object-detection-detectron2/data" folder. Create a new folder named "exdark" in the "low-light-object-detection-mmdetection/data" folder.

Download the ExDark dataset and copy the images into "low-light-object-detection-detectron2/data/exdark/images/" and "low-light-object-detection-mmdetection/data/exdark/images/" folders.

DARK FACE

Create a new folder named "darkface" in the "low-light-object-detection-detectron2/data" folder. Create a new folder named "darkface" in the "low-light-object-detection-mmdetection/data" folder.

Download the DARK FACE dataset and copy the images into "low-light-object-detection-detectron2/data/darkface/images/" and "low-light-object-detection-mmdetection/data/darkface/images/" folders.

Train

To train the ExDark and DARK FACE using FeatEnHancer based Featurized Query R-CNN run the following commands: The training utilizes 2 GPU's

sh low-light-object-detection-detectron2/train_exdark.sh
sh low-light-object-detection-detectron2/train_darkface.sh

To train the ExDark and DARK FACE using FeatEnHancer based RetinaNet run the following commands: The training utilizes 6 GPU's

sh low-light-object-detection-mmdetection/exec_script_exdark.sh
sh low-light-object-detection-mmdetection/exec_script_darkface.sh

Results and Checkpoints

ExDark

Model	mAP	Config
FeatEnHancer + Featurized Query R-CNN	86.3	config

DARK FACE

Model	mAP	Config
FeatEnHancer + Featurized Query R-CNN	69.0	config

Reproducing Results on Other Downstream Vision Tasks:

• The models developed for other downstream tasks, such as Semantic Segmentation and Video Object Detection, utilize distinct frameworks (MMDet, MMSeg, and MMTracking). Hence, it was not possible to release a unified repository at this time. However, to facilitate reproducibility of results, the same FeatEnHancer script can be employed across these different tasks.

Acknowledgment
