Implementation of 'Learning a Unified Sample Weighting Network for Object Detection' [CVPR 2020]

Learning a Unified Sample Weighting Network for Object Detection

This is the implementation of 'Learning a Unified Sample Weighting Network for Object Detection' [CVPR 2020]. The original paper can be found here.

Usage

a. Following MMDetection for installing pre-requirements.

b. clone this repo and build.

git clone https://github.com/caiqi/sample-weighting-network
cd sample-weighting-network
python setup.py develop

c. Prepare COCO dataset.

It is recommended to symlink the dataset root to sample-weighting-network/data.
