This repository contains code for object detection and tracking in videos using the YOLOv9 object detection model and the DeepSORT algorithm.

1. Clone this repository:

 git clone https://github.com/sujanshresstha/YOLOv9_DeepSORT.git
 cd YOLOv9_DeepSORT

2. Create new environment

• Using Conda

conda env create -f conda.yml
conda activate yolov9-deepsort

• Using pip

python3 -m virtualenv -p python3.11 yolov9-deepsort
source yolov9-deepsort/bin/activate
pip install -r requirements.txt

3. Clone YOLOv9 repository:

 git clone https://github.com/WongKinYiu/yolov9.git
 cd yolov9
 pip install -r requirements.txt
 mv ../object_tracking.py ../yolov9

4. Download model weight

 mkdir weights
 wget -P weights https://github.com/WongKinYiu/yolov9/releases/download/v0.1/yolov9-e.pt

1. Prepare the video file:

   • Place the video file in the desired location.
   • Update the video flag in the path of the video file or set it to 0 to use the webcam as the input.

2. Download YOLOv9 model:

   • Make sure the corresponding model weights are available.(YOLOv9-S/YOLOv9-M/YOLOv9-C/YOLOv9-E)

3. Configure the output video:

   • Update output flag in the code to specify the path and filename of the output video file.

4. Set the confidence threshold:

   • Adjust the conf flag in the code to set the confidence threshold for object detection. Objects with confidence below this threshold will be filtered out.

5. If you want to detect and track certain object on video

   • Modify the class_id flag in the code to specify the class ID for detection. The default value of the flag is set to None. If you wish to detect and track only persons, set it to 0, or refer to the coco.names file for other options.

6. If you want to blur certain object while tracking

   • Modify the bulr_id flag in the code to specify the class ID for detection. The default value of the flag is set to None.

7. Run the code:

   # Run object tracking
   python object_tracking.py --video ./data/test.mp4 --output ./output/output.mp4
   
   # Run object tracking on webcam (set video flag to 0)
   python object_tracking.py --video 0 --output ./output/webcam.mp4
   
   # Run person tracking (set class_id flag to 0 for person)
   python object_tracking.py --video ./data/test.mp4 --output ./output/output.mp4 --class_id 0
   
   # Run tracking on a video with burring certain objects (set blur_id flag to 0 for person)
   python object_tracking.py --video ./data/test.mp4 --output ./output/output.mp4 --blur_id 0
