Fingerprint Finder
Computer-vision fingerprint extraction API
The question
Can classical computer vision alone pull clean fingerprint crops out of scanned account-opening forms?
A Dockerized FastAPI microservice that detects, de-duplicates, and crops fingerprint regions from uploaded images, multi-page PDFs, and full-page web captures, with tunable detection parameters and Swagger docs.

computer visionbiometricsAPI design
This work crosses computer vision, biometrics, API design.
Adaptive thresholding, edge detection, and morphological cleanup find candidate regions; contour filtering by size and aspect ratio and an overlap threshold remove duplicates. Built to pull fingerprints out of scanned account-opening documents.
