Automatic travel pattern extraction from visa page stamps using CNN models

by   Eimantas Ledinauskas, et al.

We propose an automated document analysis system that processes scanned visa pages and automatically extracts the travel pattern from detected stamps. The system processes the page via the following pipeline: stamp detection in the visa page; general stamp country and entry/exit recognition; Schengen area stamp country and entry/exit recognition; Schengen area stamp date extraction. For each stage of the proposed pipeline we construct neural network models. We integrated Schengen area stamp detection and date, country, entry/exit recognition models together with graphical user interface into an automatic travel pattern extraction tool, which is precise enough for practical applications.
