🔥 Advantages

• Automatic creation of object masks for further tracking.
• New objects are added automatically.
• Tracking even if the object is out of frame.
• Tracking even if there are a large number of occlusions (intersections) of objects.
• Easy to use.
• Easy to change for any task.

⚠️ Some necessary information

It's multipurpose tracking approach using Yolov8, SAM, xMem and my wrapper and algorithms.
In this case it's uses for person detection, but you can simply change task (see point 4).
And I use keypoints confidence for adding good visible persons (you can remove it later).

It's not a super-approach, so maybe you will need to set hyperparameters or train models for your task. But it's very useful and easy to start project, that you can use for multiple object tracking.
On my task (person tracking) it works better that other approaches: MOT, ByteTrack, DeepSort, Kalman FIlter etc.

✅ 1. Preparing

Install all necessary libs:

pip3 install -r requirements.txt

Note: if you are using a GPU, then you need to install torch with CUDA with the GPU-enabled version. Otherwise, the processor will be used.

Download models:

python3 download_models.py

⚙️ 2. Edit config.py (can skip)

• DEVICE: if you have multiple GPUs, set device num which you want to use (or set 'cpu', but it's too slow).
• PERSON_CONF: confidence/threshold for object detection (Yolo).
• KEYPOINTS: it's my keypoints list, some of which uses to filter object bboxes by visibility (for example, if confidence of few keypoints < KPTS_CONF, we ignore that object).
• KPTS_CONF: confidence of keypoints (visibility) . if you want to change keypoints used to evaluate visibility, you can fix it in pose-estimation.py.
• IOU_THRESHOLD: when we check if new objects in frame, we check IOU between all the boxes found by Yolo and all the boxes found by the tracker, so if IOU < IOU_THRESHOLD, we check keypoints and if all is ok, it's new object which will be added.
• XMEM_CONFIG: very important for your current task. Experiment with parameters or use default settings.
• MAX_OBJECT_CNT: if you don't know value of object in your tasks, set this value very large.
• YOLO_EVERY: check new objects in frame every N frames.
• INFERENCE_SIZE: video or sequence of frames resolution.

🚀 3. Run

Tracking

You can simply run it on your video with command:

python3 tracking.py --video_path=INPUT_VIDEO_PATH.mp4 --width=1280 \
--height=768 --frames_to_propagate=600 --output_video_path=RESULT_VIDEO_PATH.mp4 --device=0 \
--person_conf=0.6 --kpts_conf=0.4 --iou_thresh=0.15 --yolo_every=2 --output_path=OUTPUT_CSV_PATH.csv

You can also set frames_to_propagate: num of frames, which you want to process. After that you can get output video with animations (detection, tracking results) and csv-file with all information about objects in every frame.

Metrics counting

I wrote custom Precision, Recall and F1Score calculation for tracking task. It compares bboxes positions and their ids.
⚠️ Please use it with labels from CVAT dataset exporting (the structure is described below)

You can simply run it on your labeled video or frames with command:

python3 metrics_counting.py --labels_dir=LABELS_DIR_PATH --width=1280 \
--height=768  --device=0 --person_conf=0.6 --kpts_conf=0.4\
--iou_thresh=0.15 --print_every=10

Note that structure of LABELS_DIR_PATH should be:

LABELS_DIR_PATH
   |- first_dir
       |- obj_train_data
           |- frame0.jpg
           |- frame0.txt
           |- frame1.jpg
           |- frame1.txt
           ...
   |- second_dir
   ...

Example. My LABELS_DIR_PATH is test_files:

Labels: Yolo
(directory with txt files corresponding to frames, format of example.txt:

0 0.265682 0.430208 0.057479 0.279509  
1 0.483107 0.486296 0.069411 0.337759  
... 
5 0.743799 0.467407 0.060016 0.289593

🎯 4. Use project for your custom tasks

It's simply to change pose-estimation.py and use different detection models (or your custom trained model):

1. Change model loading
2. In get_filtered_bboxes_by_confidence method return list with bboxes from your model
3. Enjoy 😊
