Eye Authentication System This project implements an eye authentication system using FastAPI and face_recognition. It allows users to register their faces and verify their identity by comparing captured images with stored ones.

Features User and Vendor Registration: Register users and vendors with face scans. Eye Verification: Authenticate users and vendors by comparing captured images with stored ones. Strict Similarity Threshold: Ensure accurate matches with a strict similarity threshold. Image Storage: Store images in designated directories.
