Posture Detection & Pose Classification

A simple yet advanced project based on Posture Detection & Pose Classification, developed using Python and the Flask web framework. The main objective of this application is to analyze human posture in real time and classify different yoga and exercise poses with the help of computer vision and machine learning models.

In today’s era, health, fitness, and physical well-being are becoming more important than ever. People are practicing yoga, pilates, and home workouts regularly, but one of the biggest challenges is maintaining the correct posture. Wrong postures can cause injuries, reduce the effectiveness of exercise, or create long-term health issues. This project provides a technological solution to this problem, by offering real-time posture detection and classification through a simple web application.

This project is a professional-grade paid project, but at the same time, it is an excellent choice for students and developers who want to learn the integration of computer vision, AI, and web applications. It combines different technologies like OpenCV, MediaPipe, and machine learning algorithms, making it both practical and educational.

Project Overview

The Posture Detection & Pose Classification system allows users to open a web application, turn on their webcam, and get real-time analysis of their body posture. The system can identify multiple key poses such as:

• Tree Pose

• T Pose

• Warrior II Pose

These poses are commonly used in yoga and exercise routines, which makes the project extremely relevant for fitness training, physiotherapy, and posture awareness applications.

The application provides instant feedback about whether the user is performing the pose correctly, helping them to adjust and improve their body alignment. Since it works without any external database integration, the project is lightweight, simple to use, and easy to deploy on personal computers.

How the System Works

The functioning of this project can be divided into several steps:

1. Webcam Input
   The system starts by capturing live video from the user’s webcam.

2. Body Landmark Detection
   With the help of Google’s MediaPipe library, the application detects and tracks body landmarks such as shoulders, elbows, knees, hips, and spine.

3. Feature Extraction
   The detected body landmarks are converted into numerical values (coordinates) that can be processed by the machine learning model.

4. Pose Classification
   The ML model classifies these values into predefined poses such as Tree Pose, T Pose, and Warrior II Pose.

5. Feedback and Display
   The classified posture is displayed on the web interface in real time, allowing users to correct their alignment immediately.

6. Optional Visualization
   Using Matplotlib, users can also visualize the landmark points for analysis and reporting.
