This is the official code of High-Resolution Representations for Object Detection. We extend the high-resolution representation (HRNet) [1] by augmenting the high-resolution representation by aggregating the (upsampled) representations from all the parallel convolutions, leading to stronger representations. We build a multi-level representation from the high resolution and apply it to the Faster R-CNN, Mask R-CNN and Cascade R-CNN framework. This proposed approach achieves superior results to existing single-model networks on COCO object detection. The code is based on maskrcnn-benchmark
HRNetV2 ImageNet pretrained models are now available! Codes and pretrained models are in HRNets for Image Classification
All models are trained on COCO train2017 set and evaluated on COCO val2017 set. Detailed settings or configurations are in configs/hrnet.
Note: Models are trained with the newly released code and the results have minor differences with that in the paper.
Current results will be updated soon and more models and results are comming.
All models are trained on COCO train2017 set and evaluated on COCO val2017 set. Detailed settings or configurations are in configs/hrnet.

Our HRNets will obtain larger gain when training with more iterations.
