Multi-Camera Person Tracking and Re-Identification (using video)

Simple model to "Detect/Track" and "Re-identify" individuals in different cameras/videos.

# Introduction

This project aims to track people in different videos accounting for different angles.

The framework used to accomplish this task relies on MOT and ReID to track and re-identify ID's of humans, respectively. The tracking can be completed using YOLO_v3 or YOLO_v4 and ReID relies on KaiyangZhou's Torchreid library.

# Installation

Download Anaconda if it is not installed on your machine
Clone the repository

git clone https://github.com/samihormi/Multi-Camera-Person-Tracking-and-Re-Identification

Create a project environment

cd Multi-Camera-Person-Tracking-and-Re-Identification
conda create --name py37 python=3.7
conda activate py37

Install dependencies

pip install -r requirements.txt

Install torch and torchvision based on the cuda version of your machine

conda install pytorch torchvision cudatoolkit -c pytorch

# Convert models

Download the YOLO models for YOLO_v3 and YOLO_v4 and add them to /model_data/weights/

YOLO_v3

python convert_y3.py model_data\weights\yolov3.weights model_data\models\yolov3.h5

YOLO_v4

python convert_y4.py model_data\weights\yolov4.weights model_data\models\yolov4.h5

Pre-trained models (.h5) (If you want to start right away)

Download the Keras models for YOLO_v3 and YOLO_v4 and add them to \model_data\models\
Download either one of the following Torchreid models 1,2 and add them to \model_data\models\ (you might have to change the path in reid.py)

# Demo

You can try out your own videos by running demo.py. Under the directory \videos\output, the program will generate a video of the tracking, as well as a video of the tracking and ReID. (as can be seen in the example above) You should specify the path of the videos and the version of YOLO you would like to use (v3 or v4)

python demo.py --videos videos\init\Double1.mp4 videos\init\Single1.mp4 --version v3
