1. Förfarande (900) för att jämföra ett sampel innefattande5 fingeravtrycksinformation med ett templat, nämnda förfarande innefattar att:bestämma (902) en genomsnittlig äskrökningsvektor hos samplet, ochjämföra (904) den genomsnittliga àskrökningsvektorn hos samplet medden genomsnittliga àskrökningsvektorn hos templatet,varvid den genomsnittliga àskrökningsvektorn är bestämd genom att10 identifiera ätminstone en äs i samplet,bestämma krökningsvektorn hos nämnda ätminstone en äs i ettflertal punkter av nämnda ätminstone en äs, varvid krökningsvektorn ären vektor vars längd är proportionell till hur mycket àsen är böjd ochvars riktning pekar inät mot brännpunkten hos àsen,15 beräkna ett genomsnitt av krökningsvektorerna hos nämnda ätminstone en äs i flertalet punkter av nämnda ätminstone en äs.
2. Förfarande enligt krav 1, varvid flertalet punkter av nämndaätminstone en äs är belägna pà samma äs.
3. Förfarande enligt krav 1 eller 2, varvid flertalet punkter av nämndaätminstone en äs är belägna i ett delomràde av samplet.
