  Cross-sensor comparison experimental results reported here show that the
procedure defined and simulated during the Cross-Sensor Comparison Competition
2013 by our team for migrating / upgrading LG2200 based to LG4000 based
biometric systems leads to better LG4000-to-LG2200 cross-sensor iris
recognition results than previously reported, both in terms of user comfort and
in terms of system safety. On the other hand, LG2200-to-LG400 migration/upgrade
procedure defined and implemented by us is applicable to solve interoperability
issues between LG2200 based and LG4000 based systems, but also to other pairs
of systems having the same shift in the quality of acquired images.
