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.
