This is the official implementation of our paper titled "UniHead: Unifying Multi-Perception for Detection Heads".

For more details, please refer to our paper. This repo is based on PyTorch>=1.7.1 and mmdet==2.25.1.

Our UniHead can bring significant AP improvements to a large number of detectors, even with lower model complexity.

New!!! We evaluate our UniHead on the VOC07+12 dataset. We find that our UniHead is also effective, demonstrating the generalization ability of UniHead.

We release the weight of models used in our paper, including RetinaNet, FCOS, RepPoints, FreeAnchor, ATSS and GFL. You may need to log out of your Google account to download them.

Download the weight(s) from corresponding links below.

• ATSS-UniHead (41.2 AP): Google Drive; BaiduNetDisk

• GFL-UniHead (42.3 AP): Google Drive; BaiduNetDisk

The weights of UniHead with various of backbones (R101 and SwinT) are also released. If you need more models, such as UniHead-SwinB, please feel free to contact me via email.
