# PyBodyTrack
<img src="https://github.com/bihut/pyBodyTrack/blob/main/logo.png?raw=true" alt="Ejemplo" width="300"/>

**PyBodyTrack is a library that simplifies and enhances 
movement estimation and quantification. 
It allows for the analysis of either the entire body or specific regions using various mathematical approaches, both from pre-recorded videos and real-time sources**

# **Installation Guide**

This guide explains how to install and use **PyBodyTrack**, either from **PyPI** or directly from **GitHub**.

---

## **📌 Option 1: Install from PyPI (Recommended)**
The easiest way to install **PyBodyTrack** is via **pip**:

```bash
pip install pybodytrack
```

This will automatically install the latest stable version along with all dependencies.

---

## **📌 Option 2: Install from GitHub**
If you want to use the latest development version or modify the code, follow these steps:

### **1️⃣ Create and Activate a Virtual Environment**
- Run the following command to create a new virtual environment:
  ```bash
  python -m venv my_env
  ```
- Then, activate it:
  - **Windows (Command Prompt or PowerShell):**
    ```bash
    my_env\Scripts\activate
    ```
  - **Mac/Linux:**
    ```bash
    source my_env/bin/activate
    ```
✅ **You are now inside the virtual environment.**  

---

### **2️⃣ Clone the GitHub Repository**
- Clone the repository to your local machine:
  ```bash
  git clone https://github.com/bihut/PyBodyTrack.git
  ```
- Navigate into the repository folder:
  ```bash
  cd PyBodyTrack
  ```

---

### **3️⃣ Install Dependencies**
- If the repository contains a `requirements.txt` file, install dependencies with:
  ```bash
  pip install -r requirements.txt
  ```
- If the repository uses `pyproject.toml` with **Poetry**, install dependencies using:
  ```bash
  pip install poetry
  poetry install
  ```

---

### **4️⃣ Install the Library in Editable Mode (Optional)**
- To modify the library and test changes without reinstalling, install it in **editable mode**:
  ```bash
  pip install -e .
  ```

---

### **5️⃣ Verify the Installation**
- To confirm that the library is installed correctly, try importing it:
  ```python
  import pybodytrack
  print(pybodytrack.__version__)
  ```
- If you are unsure of the package name, check the repository’s contents or `setup.py`.

---

### **6️⃣ Exit the Virtual Environment When Finished**
- Once you have finished working with the library, deactivate the virtual environment:
  ```bash
  deactivate
  ```

---

## **📌 Example**
This example illustrates the use of PyBodyTrack to track body movements in a video file:
```bash
import threading
import time
from pybodytrack.BodyTracking import BodyTracking
from pybodytrack.enums.PoseProcessor import PoseProcessor
from pybodytrack.bodyparts import body_parts as bodyparts
from pybodytrack.enums.VideoMode import VideoMode
from pybodytrack.methods.methods import Methods

# Path to the input video file
path_video = "PATH TO VIDEO"

# Initialize the BodyTracking object with the selected processor and mode
body_tracking = BodyTracking(
    processor=PoseProcessor.MEDIAPIPE,  # Use MediaPipe for pose estimation
    mode=VideoMode.VIDEO,               # Set mode to process a video file
    path_video=path_video,              # Path to the video file
    selected_landmarks=bodyparts.STANDARD_LANDMARKS  # Use standard body landmarks
)

# Define the time range for processing (in seconds)
start = 10
end = 40
body_tracking.set_times(start, end)

# Create and start a separate thread for tracking
tracker_thread = threading.Thread(target=body_tracking.start, kwargs={})
tracker_thread.start()

try:
    # Main thread stays active while the tracking thread runs
    while tracker_thread.is_alive():
        time.sleep(1)  # Prevents busy-waiting by sleeping 1 second per loop
except KeyboardInterrupt:
    print("Stopping tracking...")
    body_tracking.stop()

# Ensure proper shutdown of the tracking thread
tracker_thread.join(timeout=1)
if tracker_thread.is_alive():
    print("Tracker thread still alive. Force stopping...")
    body_tracking.stop()

# Retrieve movement data
df = body_tracking.getData()

# Compute movement metrics using Chebyshev distance
movement = Methods.chebyshev_distance(df, filter=True, distance_threshold=2.0)

# Initialize the result JSON dictionary
res_json = {}

# Compute Normalized Movement Index (NMI)
norm = body_tracking.normalized_movement_index(movement, len(bodyparts.STANDARD_LANDMARKS))
res_json['ram'] = movement  # Raw Amount of Movement (RAM)
res_json['nmi'] = norm      # Normalized Movement Index (NMI)

# Compute Movement per Landmark (MOL)
movl = body_tracking.movement_per_landmark(movement, len(bodyparts.STANDARD_LANDMARKS))
res_json['mol'] = movl

# Compute Movement per Frame (MOF)
aux = body_tracking.movement_per_frame(movement)
res_json['mof'] = aux

# Compute Movement per Second (MOS)
aux = body_tracking.movement_per_second(movement)
res_json['mos'] = aux

# Print the results
print("Raw movement:", movement, " - NMI:", norm)
```
### **⃣ Other examples can be found in "examples" folder**
### **⃣ A ready-to-use example can be found in Google Collab (https://colab.research.google.com/drive/1-XW_-IOAOICfwuKssuBBBAeVdZyELOTy?usp=sharing)**
### **⃣ Current version supports MediaPipe and YOLO. OpenPose should be installed manually (https://github.com/CMU-Perceptual-Computing-Lab/openpose)**


✅ **Now you can use PyBodyTrack either from PyPI or by installing it manually from GitHub!**  
🚀 **If you encounter any issues, feel free to open an issue on GitHub!** 😃
