Query: Automatic travel pattern extraction from visa page stamps using CNN
  models   Manual travel pattern inference from visa page stamps is a time consuming
activity and constitutes an important bottleneck in the efficiency of traveler
inspection at border crossings. Despite efforts to digitize and record the
border crossing information into databases, travel pattern inference from
stamps will remain a problem until every country in the world is incorporated
into such a unified system. This could take decades. 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 and train then on a
mixture of real and synthetic data. We integrated Schengen area stamp detection
and date, country, entry/exit recognition models together with a graphical user
interface into a prototype of an automatic travel pattern extraction tool. We
find that by combining simple neural network models into our proposed pipeline
a useful tool can be created which can speed up the travel pattern extraction
significantly.
