[ICCV 2023] FeatEnHancer: Enhancing Hierarchical Features for Object Detection and Beyond Under Low-Light Vision

Enhancing representation of a low-light image.

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

This work would not be possible without the following codebases. We gratefully thank the authors and collaborators for their wonderful works:
Featurized Query R-CNN, detectron2, mmdetection, mmsegmentation, and mmtracking
