Umlingisi we-Fingerprint Scanner ne-algorithm

Isithwebuli somunwe sithatha indawo yokhiye wendabuko ngomunwe wakho. Lapho uyisebenzisa, udinga kuphela ukubeka umunwe wakho ifulethi ewindini lokuqoqa lesithwebuli somunwe ukuqedela umsebenzi wokuvula. Ukusebenza kulula kakhulu futhi kugwema amathuba okuba khona, ukweba, nokukhohlwa kwezinye izinhlelo zokulawula ukufinyelela, ukucacisa kanye nokunye okubi. Ngakho-ke, umazi malini ngezimiso zokuqashelwa zeminwe kanye nama-algorithms.

Siyazi ukuthi ama-Fingerprints ahlukile. Lokhu kuvela empeleni kusho ukuthi iminwe yawo wonke umuntu ihlukile. Lokhu kubumbana kuyindlela yokusebenzisa iminwe ukuhlukanisa abantu abahlukahlukene. Inhloso yokuqinisekiswa kokuqashelwa kweminwe Umqondo wayo oyisisekelo ukuthola iminwe yomsebenzisi ukuthi ungene ngemvume, futhi uhambisane neminwe ngeminwe yabo bonke abasebenzisi abarekhodwe kuqala kwidatha. Umdlalo ophumelelayo ukhombisa ukuthi umsebenzisi ungumsebenzisi osemthethweni futhi ugunyaziwe ngokuya ngencazelo yemvume. Ngaphandle kwalokho, akukho emthethweni. Umsebenzisi, futhi uvikele umsebenzisi ekungeneni, ngaleyo ndlela akwazi ukuphathwa kwabasebenzi kwesakhiwo. Izinyathelo ezine ezilandelayo zisetshenziselwa ukukhomba izithombe ezahlukahlukene zeminwe, futhi izivivinyo zifakazele ukuthi le ndlela inemiphumela yokuqaphela kangcono:
1) Sebenzisa umqoqi we-Fingerprint ukuthola iminwe yomsebenzisi: Faka umqoqi we-Fingerprint emnyango wesakhiwo, uqoqe umnwetshezi womsebenzisi ngokusebenzisa leli thuluzi, bese ufaka kwikhompyutha.
2) Ukufakwa kokulungiswa kwezithombe zeminwe Inqubo yokuthola amandla lapha ukuguqula izithombe eziqoqiwe zibe zilungele kakhulu. Khomba izithombe. Izindlela eziphambili zokucubungula zifaka phakathi: Isithuthukisi sezithombe, i-Weesing Yesithombe, ukuncipha kwesithombe, ukugunyazwa, njll.
3) Ukukhishwa kwesici se-Image: Ngemuva kokuqedwa kwesithombe ukuthi kuqedwe isithombe, izici kumele zikhishwe esithombeni somunwe ukuze zikhonjwe. Izici ziyisihluthulelo sokuhlukanisa izithombe ezahlukene zeminwe. Ukuqashelwa kweminwe nokuqhathanisa kususelwa ekukhishweni kwesici. Indlela enhle yokukhishwa kwesizinda inquma ukunemba kokuqashelwa kamuva ngezinga elikhulu. Lapha sisebenzisa izixhumanisi kanye nezinkombandlela zokuqondisa zezimpawu zesithombe somunwe njenge-vector yesici sokugcina, bese usebenzisa lesi sici ukukhomba kanye nokuhlukanisa abasebenzisi abahlukahlukene.
4) Ukuqashelwa Kwephethini Yezithombe nokuqhathanisa: Ekugcineni, izithombe ezahlukahlukene zeminwe ziyafaniswa futhi zibonwa ngokususelwa kwizici ezikhishwe. Ukuze uthuthukise ukuqina kokufanisa kweminwe, izici zezici zamaphoyinti wesici ziguqulwa ngokulandelana zibe yi-polar radius, amasimu wokuqondisa nezinkomba eziqondisweni ezinhlelweni zokuxhumanisa zePolar. Indlela yebhokisi le-BIDING eguquguqukayo isetshenziselwa ukulungisa isimo se-nonlinear kanye nokwehluka kwesikhundla okwenziwe ngesikhathi senqubo yokutholwa kwesithombe.
Izinhlelo zokulawula ukufinyelela zivame ukuqukethe abalawuli, abafundi beKhadi, okhiye abalawulwa ngogesi, izinkinobho zokuvula umnyango, isoftware yokulawula ukungena, abaphathi bezokuxhumana, abaphathi bezokuphatha, njll. Ngalesi sisekelo , leli phepha liklama uhlelo lokulawula ukufinyelela olususelwa ekuqinisekisweni kweminwe. Ukwakhiwa kwalo lonke uhlelo kungahlukaniswa nge-module ye-Bouth Network Advard yohlobo lokulawula ukufinyelela kanye nemodyuli yokuqashelwa kokuqashelwa kweminwe. Imodyuli yezokwakheka yenethiwekhi engokomzimba ifaka phakathi ukwakheka ngokomzimba kohlelo lokulawula ukufinyelela kanye nokufakwa kwamathuluzi kanye nemishini, ngaleyo ndlela kwakha ukwakheka kwawo wonke ama-module wokulawula ukufinyelela ikakhulukazi kubandakanya ukwakheka kanye nokusungulwa kwesoftware kanye nokusungulwa Yemininingwane yomsebenzisi ogunyaziwe yomsebenzisi, osetshenziswayo ngale software yokufakazela ubuqiniso kweminwe yomsebenzisi.
Uhlelo lokuqinisekisa ukuqinisekiswa kweminwe lwe-algorithm lusebenzisa idizayini yemodyuli ye-hierarchical futhi ihlukaniswe ngezingqimba ezintathu. Isendlalelo esingezansi kufaka phakathi imodyuli yetafula ledatha, imodyuli ye-classifier kanye netabhulali ye-template Fingerprint; Isendlalelo esiphakathi yisendlalelo se-interface, kufaka phakathi isibonisi sokukhishwa kwesici, isici sokuqhathanisa esibonakalayo kanye nesibonisi seminwe yokusebenza kweminwe; Isendlalelo esingenhla iyisethi yokufaka isicelo, kufaka phakathi ukubhaliswa kweminwe, ukuqinisekiswa kweminwe, ukuhlonza iminwe kanye nokuphathwa kweminwe.
Le module kuqala ikhipha isithombe somunwe seminwe yedatha yomsebenzisi egunyaziwe, ikhipha izixhumanisi kanye nenkambu yokuqondisa yomunwe womunwe, isungule i-database yesici somunwe, futhi iqondise ku-database. Ohlelweni lokulawula ukufinyelela, izici zeminwe zomsebenzisi ongena ngemvume zitholakala ngomqokeleli, futhi zifaniswe nedatha ku-database ukuthola ukuthi umsebenzisi uvunyelwe yini ukungena.
