Posture Detection Using Machine Learning and Python
The Posture Detection Using Machine Learning in Python and Pose Classification project is a computer vision application developed using Python and the Flask web framework. Its primary objective is to analyze human body posture in real time and classify different yoga and exercise poses using computer vision and machine learning techniques.
Maintaining the correct posture during yoga, exercise, and fitness activities is important for body alignment and movement awareness. This project provides a technology-based approach to observing body positions through webcam input. It detects body landmarks, processes their coordinates, and classifies predefined poses through a web-based interface.
The project combines Python, Flask, MediaPipe, OpenCV, and machine learning concepts in one application. It is suitable for students and developers interested in artificial intelligence, computer vision, and web application development.

Project Overview of the Posture Detection Using Machine Learning
The Posture Detection and Pose Classification system allows users to open a web application, activate their webcam, and receive real-time pose classification results. The application identifies predefined poses such as Tree Pose, T Pose, and Warrior II Pose.
Using MediaPipe, the system detects body landmarks such as the shoulders, elbows, hips, and knees. The detected landmarks are converted into numerical coordinates, which can be processed by a machine learning model. The resulting classification is displayed through the Flask web interface.
The project is designed without requiring an external database. This keeps the described application architecture relatively lightweight and reduces the need for database configuration during setup. The included project report and documentation can help students understand the system’s structure and implementation.

1. Webcam Input
The system begins by capturing live video from the user’s webcam. The video frames provide the visual information needed for posture analysis. The application processes these frames to examine the user’s body position during an exercise or yoga pose.
2. Body Landmark Detection
MediaPipe is used to detect and track relevant human body landmarks. These landmarks can include the shoulders, elbows, hips, knees, and other body points. Their positions provide information about the arrangement of different body parts.
Landmark detection is an important stage because the subsequent classification process relies on the information extracted from the detected body position.
3. Feature Extraction
After detecting body landmarks, the system converts their positions into numerical coordinates. These values serve as features for the classification process. Instead of relying only on the raw video image, the application uses the extracted landmark information to represent the user’s body position.
4. Pose Classification
The machine learning model processes the extracted information and classifies the pose into one of the predefined categories. The project description identifies Tree Pose, T Pose, and Warrior II Pose as supported examples.
5. Feedback and Display
The classification result is displayed through the Flask-powered web interface. Users can observe which predefined pose the application identifies from the webcam input. This provides a way to monitor body positioning during practice.
6. Optional Visualization
Matplotlib can be used for optional visualization of body landmark points. These visualizations can support analysis, observation, and reporting while learning how the system represents human poses numerically.
