Projects
YOLOv8n · ONNX Runtime · WebRTC · Leaflet.js · PWA · Nepali TTS
Visually impaired pedestrians in Nepal navigate streets filled with hazards that no global object detector recognizes — auto-rickshaws, exposed electric poles. Generic models trained on Western datasets systematically miss these obstacles, making existing assistive tools unreliable in South Asian urban environments.
Fine-tuned YOLOv8n on a custom Nepal-specific hazard dataset and compiled it to ONNX for fully client-side inference via the browser. Combined with WebRTC for camera access, Leaflet.js for location context, and a Nepali text-to-speech engine to deliver real-time audio guidance — all packaged as a progressive web app with zero server dependency.
A deployable PWA that runs detection at inference-level speed directly on a phone browser, delivering contextual Nepali audio cues for obstacles in real time. Eliminates server latency, reduces infrastructure costs to near-zero, and proves that domain-specific fine-tuning is essential for assistive AI in underserved regions.
Implementation Note
Video calling is disabled in the live demo because it requires STUN/TURN infrastructure for reliable peer-to-peer connectivity. While Cloudflare provides a limited free allocation, the feature has been disabled to avoid unexpected usage costs
