Real-Time Squat Counter using Computer Vision

A lightweight and efficient real-time squat detection and repetition counter built using pose estimation and knee angle tracking. Designed for edge devices, this system provides live feedback on workout performance.

How It Works

1. Pose Estimation
   Detects human keypoints (hips, knees, ankles) using a lightweight model.

2. Angle Calculation
   Computes the knee joint angle using 3 keypoints:

   • Hip
   • Knee
   • Ankle

3. Rep Counting Logic

   • Detects downward motion (squat)
   • Detects upward motion (standing)
   • Counts one full rep per cycle

4. Posture Analysis

   • Ensures correct squat depth
   • Flags improper form (e.g., shallow squats)
