Real-time multi-object, segmentation and pose tracking using Yolov8 | Yolo-NAS | YOLOX with DeepOCSORT and LightMBN
This repo contains a collections of pluggable state-of-the-art multi-object trackers for object detectors. We provide examples on how to use this package together with popular object detection models such as: Yolov8, Yolo-NAS and YOLOX.
Supported tracking methods
DeepOCSORT , BoTSORT , StrongSORT, OCSORT and ByteTrack. DeepOCSORT, BoTSORT and StrongSORT are based on motion + appearance description; OCSORT and ByteTrack are based on motion only. For the methods using appearance description, lightweight state-of-the-art ReID models (LightMBN, OSNet and more) are downloaded automatically as well.
Tutorials
Experiments
In inverse chronological order:
Everything is designed with simplicity and flexibility in mind. We don't hyperfocus on results on a single dataset, we prioritize real-world results. If you don't get good tracking results on your custom dataset with the out-of-the-box tracker configurations, use the examples/evolve.py script for tracker hyperparameter tuning.
Start with Python>=3.8 environment.
If you want to run the YOLOv8, YOLO-NAS or YOLOX examples:
git clone https://github.com/mikel-brostrom/yolo_tracking.git
pip install -v -e .
but if you only want to import the tracking modules you can simply:
pip install boxmot
Tracking
Yolo models
$ python examples/track.py --yolo-model yolov8n # bboxes only
python examples/track.py --yolo-model yolo_nas_s # bboxes only
python examples/track.py --yolo-model yolox_n # bboxes only
yolov8n-seg # bboxes + segmentation masks
yolov8n-pose # bboxes + pose estimation
Tracking methods
$ python examples/track.py --tracking-method deepocsort
strongsort
ocsort
bytetrack
botsortTracking sources
Tracking can be run on most video formats
$ python examples/track.py --source 0 # webcam
img.jpg # image
vid.mp4 # video
path/ # directory
path/*.jpg # glob
'https://youtu.be/Zgi9g1ksQHc' # YouTube
'rtsp://example.com/media.mp4' # RTSP, RTMP, HTTP streamSelect ReID model
Some tracking methods combine appearance description and motion in the process of tracking. For those which use appearance, you can choose a ReID model based on your needs from this ReID model zoo. These model can be further optimized for you needs by the reid_export.py script
$ python examples/track.py --source 0 --reid-model lmbn_n_cuhk03_d.pt
osnet_x0_25_market1501.pt
mobilenetv2_x1_4_msmt17.engine
resnet50_msmt17.onnx
osnet_x1_0_msmt17.pt
...Filter tracked classes
By default the tracker tracks all MS COCO classes.
If you want to track a subset of the classes that you model predicts, add their corresponding index after the classes flag,
python examples/track.py --source 0 --yolo-model yolov8s.pt --classes 16 17 # COCO yolov8 model. Track cats and dogs, onlyHere is a list of all the possible objects that a Yolov8 model trained on MS COCO can detect. Notice that the indexing for the classes in this repo starts at zero
MOT compliant results
Can be saved to your experiment folder runs/track/exp*/ by
python examples/track.py --source ... --save-motEvaluation
Evaluate a combination of detector, tracking method and ReID model on standard MOT dataset or you custom one by
$ python3 examples/val.py --yolo-model yolo_nas_s.pt --reid-model osnetx1_0_dukemtcereid.pt --tracking-method deepocsort --benchmark MOT16
--yolo-model yolox_n.pt --reid-model osnet_ain_x1_0_msmt17.pt --tracking-method ocsort --benchmark MOT17
--yolo-model yolov8s.pt --reid-model lmbn_n_market.pt --tracking-method strongsort --benchmark <your-custom-dataset>Evolution
We use a fast and elitist multiobjective genetic algorithm for tracker hyperparameter tuning. By default the objectives are: HOTA, MOTA, IDF1. Run it by
$ python examples/evolve.py --tracking-method strongsort --benchmark MOT17 --n-trials 100 # tune strongsort for MOT17
--tracking-method ocsort --benchmark <your-custom-dataset> --objective HOTA # tune ocsort for maximizing HOTA on your custom tracking datasetThe set of hyperparameters leading to the best HOTA result are written to the tracker's config file.
