Overlaid squares indicate the Finder Patterns (FIPs), present in three corners of any QR code, that have been
detected by the Viola-Jones classifier used in our approach. Line segments indicate pairs of candidate FIPS
that have been considered as potentially being part of a same QR code. The red line segments indicate
those that have been considered as part of QR codes.
