Automatic travel pattern extraction from visa page stamps using CNN models. (arXiv:2112.00348v2 [cs.CV] UPDATED)

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 …
