Project Overview

Transform your computer interactions with gesture-based technology that eliminates traditional input devices. I've created three advanced computer vision systems using Generative AI assistance that enable truly hands-free computing: a hand gesture recognition engine, a face detection and verification system, and an interactive box manipulation interface. These systems feature real-time video processing and adaptive interfaces that respond naturally to human movement, turning your webcam into a sophisticated input device.

  • Hand gesture recognition engine that identifies common hand poses
  • Face detection and verification system with real-time analysis
  • Interactive box manipulation interface controlled entirely through hand movements

These systems feature real-time video processing and adaptive interfaces that respond naturally to human movement, turning your webcam into a sophisticated input device.

Generative AI played a crucial role in refining algorithms and improving accuracy across diverse lighting and environmental conditions.


# Hand tracking with MediaPipe
mp_hands = mp.solutions.hands
hands = mp_hands.Hands(max_num_hands=1, min_detection_confidence=0.7)

# Gesture recognition with distance calculations
def recognize_gesture(landmarks):
    # Analyze fingertip positions relative to wrist
    # Return specific gesture based on pattern detection
          
  • Gesture Recognition Engine: Uses relative distances between wrist and fingertips
  • Face Detection System: Template matching approach with adjustable similarity thresholds
  • Interactive Box System: Natural manipulation interface with smooth interpolation
  • Gesture History Tracking: Majority-voting algorithm for stable detection

Learning Outcomes

This project deepened my expertise in computer vision and AI-assisted development, yielding valuable insights:

Mastering the Vision Pipeline: From Camera to Action

By developing these systems, I gained comprehensive knowledge of end-to-end computer vision workflows—capturing video streams, processing frames in real-time, and translating visual data into meaningful interactions.

Decoding the Language of Hands: Gesture Recognition Expertise

I developed advanced techniques for analyzing hand landmarks, creating algorithms that recognize intuitive gestures across different users without requiring individual calibration.

Cracking the Face Detection Puzzle: Identity Verification Mastery

Working with both Haar Cascades and template matching taught me practical approaches to facial detection and verification that balance security with performance constraints.

Designing Interfaces That Feel Magical: Real-time Interaction Engineering

I learned to create responsive yet stable interfaces that feel natural to users, implementing techniques like gesture history tracking and movement smoothing for optimal user experiences.
