Computer Vision & Edge Biometric Verification

System Architecture & Overview

An edge-accelerated computer vision attendance system leveraging lightweight deep neural networks with 3D depth-texture anti-spoofing verification, achieving 99.4% accuracy under varying lighting conditions.

The Challenge / Problem

Manual attendance taking in university halls wastes up to 15 minutes per lecture and is vulnerable to proxy signing.

Engineering Solution

Architected a dual-stream facial recognition camera pipeline running locally on edge hardware with encrypted cloud synchronization.

Technical Hardening & Challenges

Edge hardware optimization, inference speed under 40ms, and robust anti-spoofing against photo and video replays.

Commercial & Production Result

99.4% verification accuracy, 35ms face detection speed, zero successful spoof attempts in trials.

Pipeline & Architecture Flow

OpenCV Stream -> Face Landmark Extractor -> Liveness Classifier -> Vector Embedding Comparison -> SQLite/Cloud Sync.
