This includes detectors performing tasks such as object or keypoint detection (see [examples](#examples--demos)).\n\n- Modular. It can easily be inserted into complex video processing pipelines to add tracking to existing projects. At the same time, it is possible to build a video inference loop from scratch using just Norfair and a detector.\n\n- Supports moving camera, re-identification with appearance embeddings, and n-dimensional object tracking (see [Advanced features](#advanced-features)).\n\n- Norfair provides several predefined distance functions to compare tracked objects and detections. The distance functions can also be defined by the user, enabling the implementation of different tracking strategies.\n\n- Fast. The only thing bounding inference speed will be the detection network feeding detections to Norfair.\n\nNorfair is built, used and maintained by [Tryolabs](https://tryolabs.com).\n\n## Installation\n\nNorfair currently supports Python 3.7+.\n\nFor the minimal version, install as:\n\n```bash\npip install norfair\n```\n\nTo make Norfair install the dependencies to support more features, install as:\n\n```bash\npip install norfair[video]  # Adds several video helper features running on OpenCV\npip install norfair[metrics]  # Supports running MOT metrics evaluation\npip install norfair[metrics,video]  # Everything included\n```\n\nIf the needed dependencies are already present in the system, installing the minimal version of Norfair is enough for enabling the extra features. This is particularly useful for embedded devices, where installing compiled dependencies can be difficult, but they can sometimes come preinstalled with the system.\n\n## Documentation\n\n[Getting started guide](https://tryolabs.github.io/norfair/latest/getting_started/).\n\n[Official reference](https://tryolabs.github.io/norfair/latest/reference/).\n\n## Examples & demos\n\n[![Hugging Face Spaces](https://img.shields.io/badge/%F0%9F%A4%97%20Hugging%20Face-Spaces-blue)](https://huggingface.co/spaces/tryolabs/norfair-demo)\n[![Open in Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/tryolabs/norfair/blob/master/demos/colab/colab_demo.ipynb)\n\nWe provide several examples of how Norfair can be used to add tracking capabilities to different detectors, and also showcase more advanced features.\n\n> Note: for ease of reproducibility, we provide Dockerfiles for all the demos. Even though Norfair does not need a GPU, the default configuration of most demos requires a GPU to be able to run the detectors. For this, make sure you install [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html) so that your GPU can be shared with Docker.\n>\n> It is possible to run several demos with a CPU, but you will have to modify the scripts or tinker with the installation of their dependencies.\n\n### Adding tracking to different detectors\n\nMost tracking demos are showcased with vehicles and pedestrians, but the detectors are generally trained with many more classes from the [COCO dataset](https://cocodataset.org/).\n\n1. [YOLOv7](https://github.com/tryolabs/norfair/tree/master/demos/yolov7): tracking object centroids or bounding boxes.\n2. [YOLOv5](https://github.com/tryolabs/norfair/tree/master/demos/yolov5): tracking object centroids or bounding boxes.\n3. [YOLOv4](https://github.com/tryolabs/norfair/tree/master/demos/yolov4): tracking object centroids.\n4. [Detectron2](https://github.com/tryolabs/norfair/tree/master/demos/detectron2): tracking object centroids.\n5. [AlphaPose](https://github.com/tryolabs/norfair/tree/master/demos/alphapose): tracking human keypoints (pose estimation) and inserting Norfair into a complex existing pipeline using.\n6. [OpenPose](https://github.com/tryolabs/norfair/tree/master/demos/openpose): tracking human keypoints.\n7. [Tracking](https://github.com/tryolabs/norfair/tree/master/demos/yolopv2) objects with [YOLOPv2](https://github.com/CAIC-AD/YOLOPv2), a model for traffic object detection, drivable road area segmentation, and lane line detection.\n\n### Advanced features\n\n1. [Speed up pose estimation by extrapolating detections](https://github.com/tryolabs/norfair/tree/master/demos/openpose) using [OpenPose](https://github.com/CMU-Perceptual-Computing-Lab/openpose).\n2. [Track both bounding boxes and human keypoints](https://github.com/tryolabs/norfair/tree/master/demos/keypoints_bounding_boxes) (multi-class), unifying the detections from a YOLO model and OpenPose.\n3. [Re-identification (ReID)](https://github.com/tryolabs/norfair/tree/master/demos/reid) of tracked objects using appearance embeddings. This is a good starting point for scenarios with a lot of occlusion, in which the Kalman filter alone would struggle.\n4. [Accurately track objects even if the camera is moving](https://github.com/tryolabs/norfair/tree/master/demos/camera_motion), by estimating camera motion potentially accounting for pan, tilt, rotation, movement in any direction, and zoom.\n5. [Track points in 3D](https://github.com/tryolabs/norfair/tree/master/demos/3d_track), using [MediaPipe Objectron](https://google.github.io/mediapipe/solutions/objectron.html).\n6. [Tracking of small objects](https://github.com/tryolabs/norfair/tree/master/demos/sahi), using [SAHI: Slicing Aided Hyper Inference](https://github.com/obss/sahi).\n\n### ROS integration\n\nTo make it even easier to use Norfair in robotics projects, we now offer a version that integrates with the Robotic Operating System (ROS).\n\nWe present a [ROS package](https://github.com/tryolabs/norfair-ros) and a [fully functional environment](https://github.com/tryolabs/norfair-ros-dev) running on Docker to do the first steps with this package and start your first application easier.\n\n### Benchmarking and profiling\n\n1. [Kalman filter and distance function profiling](https://github.com/tryolabs/norfair/tree/master/demos/profiling) using [TRT pose estimator](https://github.com/NVIDIA-AI-IOT/trt_pose).\n2. Computation of [MOT17](https://motchallenge.net/data/MOT17/) scores using [motmetrics4norfair](https://github.com/tryolabs/norfair/tree/master/demos/motmetrics4norfair).\n\n![Norfair OpenPose Demo](https://raw.githubusercontent.com/tryolabs/norfair/master/docs/videos/openpose_skip_3_frames.gif)\n\n## How it works\n\nNorfair works by estimating the future position of each point based on its past positions. It then tries to match these estimated positions with newly detected points provided by the detector. For this matching to occur, Norfair can rely on any distance function. There are some predefined distances already integrated in Norfair, and the users can also define their own custom distances. Therefore, each object tracker can be made as simple or as complex as needed.\n\nAs an example we use [Detectron2](https://github.com/facebookresearch/detectron2) to get the single point detections to use with this distance function. We just use the centroids of the bounding boxes it produces around cars as our detections, and get the following results.\n\n![Tracking cars with Norfair](https://raw.githubusercontent.com/tryolabs/norfair/master/docs/videos/traffic.gif)\n\nOn the left you can see the points we get from Detectron2, and on the right how Norfair tracks them assigning a unique identifier through time. Even a straightforward distance function like this one can work when the tracking needed is simple.\n\nNorfair also provides several useful tools for creating a video inference loop. Here is what the full code for creating the previous example looks like, including the code needed to set up Detectron2:\n\n```python\nimport cv2\nimport numpy as np\nfrom detectron2.config import get_cfg\nfrom detectron2.engine import DefaultPredictor\n\nfrom norfair import Detection, Tracker, Video, draw_tracked_objects\n\n# Set up Detectron2 object detector\ncfg = get_cfg()\ncfg.merge_from_file("demos/faster_rcnn_R_50_FPN_3x.yaml")\ncfg.MODEL.ROI_HEADS.SCORE_THRESH_TEST = 0.5\ncfg.MODEL.WEIGHTS = "detectron2://COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x/137849600/model_final_f10217.pkl"\ndetector = DefaultPredictor(cfg)\n\n# Norfair\nvideo = Video(input_path="video.mp4")\ntracker = Tracker(distance_function="euclidean", distance_threshold=20)\n\nfor frame in video:\n    detections = detector(cv2.cvtColor(frame, cv2.COLOR_BGR2RGB))\n    detections = [Detection(p) for p in detections[\'instances\'].pred_boxes.get_centers().cpu().numpy()]\n    tracked_objects = tracker.update(detections=detections)\n    draw_tracked_objects(frame, tracked_objects)\n    video.write(frame)\n```\n\nThe video and drawing tools use OpenCV frames, so they are compatible with most Python video code available online. The point tracking is based on [SORT](https://arxiv.org/abs/1602.00763) generalized to detections consisting of a dynamically changing number of points per detection.\n\n## Motivation\n\nTrying out the latest state-of-the-art detectors normally requires running repositories that weren\'t intended to be easy to use. These tend to be repositories associated with a research paper describing a novel new way of doing detection, and they are therefore intended to be run as a one-off evaluation script to get some result metric to publish on a particular research paper. This explains why they tend to not be easy to run as inference scripts, or why extracting the core model to use in another standalone script isn\'t always trivial.\n\nNorfair was born out of the need to quickly add a simple layer of tracking over a wide range of newly released SOTA detectors. It was designed to seamlessly be plugged into a complex, highly coupled code base, with minimum effort. Norfair provides a series of modular but compatible tools, which you can pick and choose to use in your project.\n\n## Comparison to other trackers\n\nNorfair\'s contribution to Python\'s object tracker library repertoire is its ability to work with any object detector by being able to work with a variable number of points per detection, and the ability for the user to heavily customize the tracker by creating their own distance function.\n\nIf you are looking for a tracker, here are some other projects worth noting:\n\n- [**OpenCV**](https://opencv.org) includes several tracking solutions like [KCF Tracker](https://docs.opencv.org/3.4/d2/dff/classcv_1_1TrackerKCF.html) and [MedianFlow Tracker](https://docs.opencv.org/3.4/d7/d86/classcv_1_1TrackerMedianFlow.html) which are run by making the user select a part of the frame to track, and then letting the tracker follow that area. They tend not to be run on top of a detector and are not very robust.\n- [**dlib**](http://dlib.net) includes a correlation single object tracker. You have to create your own multiple object tracker on top of it yourself if you want to track multiple objects with it.\n- [**AlphaPose**](https://github.com/MVIG-SJTU/AlphaPose) just released a new version of their human pose tracker. This tracker is tightly integrated into their code base, and to the task of tracking human poses.\n- [**SORT**](https://github.com/abewley/sort) and [**Deep SORT**](https://github.com/nwojke/deep_sort) are similar to this repo in that they use Kalman filters (and a deep embedding for Deep SORT), but they are hardcoded to a fixed distance function and to tracking boxes. Norfair also adds some filtering when matching tracked objects with detections, and changes the Hungarian Algorithm for its own distance minimizer. Both these repos are also released under the GPL license, which might be an issue for some individuals or companies because the source code of derivative works needs to be published.\n\n## Benchmarks\n\n[MOT17](https://motchallenge.net/data/MOT17/) and [MOT20](https://motchallenge.net/data/MOT17/) results obtained using [motmetrics4norfair](https://github.com/tryolabs/norfair/tree/master/demos/motmetrics4norfair) demo script on the `train` split. We used detections obtained with [ByteTrack\'s](https://github.com/ifzhang/ByteTrack) YOLOX object detection model.\n\n| MOT17 Train |   IDF1 IDP IDR    | Rcll  | Prcn  |  MOTA MOTP  |\n| :---------: | :---------------: | :---: | :---: | :---------: |\n|  MOT17-02   | 61.3% 63.6% 59.0% | 86.8% | 93.5% | 79.9% 14.8% |\n|  MOT17-04   | 93.3% 93.6% 93.0% | 98.6% | 99.3% | 97.9% 07.9% |\n|  MOT17-05   | 77.8% 77.7% 77.8% | 85.9% | 85.8% | 71.2% 14.7% |\n|  MOT17-09   | 65.0% 67.4% 62.9% | 90.3% | 96.8% | 86.8% 12.2% |\n|  MOT17-10   | 70.2% 72.5% 68.1% | 87.3% | 93.0% | 80.1% 18.7% |\n|  MOT17-11   | 80.2% 80.5% 80.0% | 93.0% | 93.6% | 86.4% 11.3% |\n|  MOT17-13   | 79.0% 79.6% 78.4% | 90.6% | 92.0% | 82.4% 16.6% |\n|   OVERALL   | 80.6% 81.8% 79.6% | 92.9% | 95.5% | 88.1% 11.9% |\n\n| MOT20 Train |   IDF1 IDP IDR    | Rcll  | Prcn  |  MOTA MOTP  |\n| :---------: | :---------------: | :---: | :---: | :---------: |\n|  MOT20-01   | 85.9% 88.1% 83.8% | 93.4% | 98.2% | 91.5% 12.6% |\n|  MOT20-02   | 72.8% 74.6% 71.0% | 93.2% | 97.9% | 91.0% 12.7% |\n|  MOT20-03   | 93.0% 94.1% 92.0% | 96.1% | 98.3% | 94.4% 13.7% |\n|  MOT20-05   | 87.9% 88.9% 87.0% | 96.0% | 98.1% | 94.1% 13.0% |\n|   OVERALL   | 87.3% 88.4% 86.2% | 95.6% | 98.1% | 93.7% 13.2% |\n\n## Commercial support\n\nTryolabs can provide commercial support, implement new features in Norfair or build video analytics tools for solving your challenging problems.
