BorderDet
This project provides an implementation for "BorderDet: Border Feature for Dense Object Detection" (ECCV2020 Oral) on PyTorch.
For the reason that experiments in the paper were conducted using internal framework, this project reimplements them on cvpods and reports detailed comparisons below.
Requirements
- Python >= 3.6
- PyTorch >= 1.3
- torchvision >= 0.4.2
- OpenCV
- pycocotools: pip install cython; pip install 'git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI'
- GCC >= 4.9
Get Started
git clone --recursive https://github.com/Megvii-BaseDetection/BorderDet
cd BorderDet

Results on COCO
For your convenience, we provide the performance of the following trained models. All models are trained with 16 images in a mini-batch and frozen batch normalization. All model including X_101/DCN_X_101 will be released soon.
