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.
how it is put together
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.
Connections
Other work that sits in some of the same fields. The overlap is what the map draws.
