DESCRIPTION = """# MMDetection
This is an unofficial demo for [https://github.com/open-mmlab/mmdetection](https://github.com/open-mmlab/mmdetection).
This space demonstrates the use of an integration of Vision pretained models from Open MMlab and hugging face hub. Model configurations and checkpoints are uploaded to hugging face space and can be used for inference directly from [MMdetection](https://github.com/open-mmlab/mmdetection) library.
With this demo, object detection using the Mask R-CNN & Faster R-CNN model can be performed.
You can upload image files, or use the example files below.
For more information on the Models, find some helpful resources below.
- Pretrained model from [OpenMMlab](https://github.com/open-mmlab/mmdetection)

Detection with Region Proposal Networks](https://arxiv.org/pdf/1506.01497.pdf)
