Introduction

Welcome to DAMO-YOLO! It is a fast and accurate object detection method, which is developed by TinyML Team from Alibaba DAMO Data Analytics and Intelligence Lab. And it achieves a higher performance than state-of-the-art YOLO series. DAMO-YOLO is extend from YOLO but with some new techs, including Neural Architecture Search (NAS) backbones, efficient Reparameterized Generalized-FPN (RepGFPN), a lightweight head with AlignedOTA label assignment, and distillation enhancement. For more details, please refer to our Arxiv Report. Moreover, here you can find not only powerful models, but also highly efficient training strategies and complete tools from training to deployment.

Model Zoo

General Models

• We report the mAP of models on COCO2017 validation set, with multi-class NMS.
• The latency in this table is measured without post-processing(NMS).
• * denotes the model trained with distillation.
• We use S as teacher to distill T, and M as teacher to distill S, ans L as teacher to distill M, while L is distilled by it self.

Light Models

• We report the mAP of models on COCO2017 validation set, with multi-class NMS.
• The latency in this table is measured without post-processing, following picodet.
• The latency is evaluated based on OpenVINO-2022.3.0, using commands below:

  # onnx export, enable --benchmark to ignore postprocess
  python tools/converter.py -f configs/damoyolo_tinynasL18_Ns.py -c ../damoyolo_tinynasL18_Ns.pth --batch_size 1  --img_size 416 --benchmark
  # model transform
  mo --input_model damoyolo_tinynasL18_Ns.onnx --data_type FP16
  # latency benchmark
  ./benchmark_app -m damoyolo_tinynasL18_Ns.xml -i ./assets/dog.jpg -api sync -d CPU -b 1 -hint latency 

701 categories DAMO-YOLO Model

We provide DAMO-YOLO-S model with 701 categories for general object detection, which has been trained on a large dataset including COCO, Objects365 and OpenImage. This model can also serve as a pre-trained model for fine-tuning in downstream tasks, enabling you to achieve better performance with ease.

• Note: The downloadable model is a pretrained model with 701 categories datasets. We demonstrate the VisDrone results to show that our pretrained model can enhance the performance of downstream tasks.
