Yini ukuhlukaniswa kwezinhlelo zokulawula ukufinyelela kwe-biometric?

I-Hardware yohlelo lokuqashelwa Kwesikhathi Stream ihlanganiswa ikakhulukazi i-microprocessor, imodyuli yokuqashelwa yesikhathi sokufunda, imodyuli yokubonisa ye-Crystal Time, ikhibhodi, i-Chip / Ikhaleji Chip, ilokhi elawulwa ngogesi kanye nokuhanjiswa kwamandla. I-microprocessor, njengekhompyutha ephezulu yohlelo, ilawula uhlelo lonke. Ukuhlonzwa kweminwe kanye nemodyuli yokubakhona ikakhulukazi kuqeda ukuqoqwa, ukuqhathanisa, ukugcinwa nokususwa kwezici zeminwe. Imodyuli yokubonisa ye-Liquid Crystal isetshenziselwa ukukhombisa imininingwane efana namarekhodi okuvula emnyango, iwashi lesikhathi sangempela kanye nokusebenza okubonakalayo, futhi kwakha i-interface yomshini womuntu kanye nekhibhodi.

Idivayisi yokufunda yeminwe (umqoqi) isebenzisa ubuchwepheshe bezithombe ze-PhotoElectric noma ubuchwepheshe be-capacive ukuqoqa imininingwane yeminwe, bese ukhipha izici futhi uzifafaze ngolwazi olugciniwe ukuze uqedele inqubo yokuhlonza. Le nqubo iqediwe kudivayisi yokufunda, noma idivaysi yokufunda ingaqoqa kuphela izigxivizo zeminwe, bese uyidlulisela kwimishini yasemuva (efana ne-PC) ukuqedela isizinda sesici nokukhonjwa. Idivayisi yokuqoqa ngokwahlukana kwezithombe zeminwe kulula kakhulu ukukwenza okuncane, okulula ukuyisebenzisa, futhi ijubane lokuhlonza uhlelo nalo lishesha kakhulu. Ukuqoqwa kwezici zeminwe zeminwe kudinga ukusungulwa kobudlelwano obekiwe phakathi komunwe womuntu kanye nomqoqi ngesikhathi sokusebenza. Ngakho-ke, uhlelo lunobungane kangako.
Ama-BioStatistics akhombisa ukuthi ama-Fingerprints anengqondo ephezulu, futhi amathuba eminwe afanayo avela phakathi kwabantu aphansi kakhulu, ngenxa yokuphepha okuphezulu, kepha kusekhona ingozi yokukopishwa. Ngakho-ke, imikhiqizo enomsebenzi wokuqoqwa kweminwe ophilayo ivele, ikakhulukazi ukwandisa ukutholwa kwezinga lokushisa, ukuqina, kanye nama-microvesels ukuqinisekisa ubuqiniso beminwe yeminwe eqoqiwe. Ngohlelo lokulawula ukufinyelela olunezidingo zokuphepha, ngaphezu kokuhlonzwa kweminwe nokubakhona kweminwe, ezinye izindlela zokuhlonza, ezinjengamaphasiwedi, kufanele zengezwe ukuze zithuthukise ukuphepha kohlelo.
1. Uhlelo Lokulawula Ukufinyelela Kwezikhathi Zokufinyelela
Imininingwane etholakala e-Palmprint icebile, futhi ubunikazi bomuntu bunganqunywa ngokuphelele ngokusebenzisa i-Line Pictures, amaphoyinti izici, izici zokuthungwa, kanye nezici zejometri ze-Palmprint. Isisekelo sobuchwepheshe be-Palm Recoution Atterance Atterance ukuqashelwa kwe-Palm Geometry. Ukuqashelwa kwe-Palm geometry ukubona izici zesandla somsebenzisi neminwe, nemikhiqizo ethuthukisiwe nayo ingabona izithombe ezinezici ezintathu.
Ukuqashelwa kwe-Gememetry yesundu kulula ukuyisebenzisa. Ilungele izimo ezinenombolo enkulu yabasebenzisi noma ukwamukelwa okulula, futhi ukunemba kuphezulu kakhulu. Ngaphansi kwesibili, ubunikazi bomsebenzisi buqinisekisiwe ngokuthola izici ezinezici ezintathu ezifana nosayizi, ukwakheka, nendawo engaphezulu yesandla sangaphandle yomsebenzisi, ukuze baqinisekise ukuthi abasebenzi abagunyaziwe kuphela abangafaka izindawo ezithile, ngakho-ke njengokufeza inhloso yokulawula ukufinyelela. Njengenye indlela ohlelweni lokulawula ukufinyelela kwamakhadi omsakazo, uhlelo lokulawula ukuphrinta kwePalm lunika abasebenzisi ukuthi balondoloze izindleko zokusebenzisa nokuphatha amakhadi, futhi bangasetshenziswa ngokuhlanganiswa nezinye izinhlelo zokulawula ukufinyelela ukwandisa ukuphepha. Uma kuqhathaniswa nohlelo lokuqashelwa kweminwe, uhlelo lokuqashelwa kwesundu lunokungcola nezibazi ezingakuphazamisi ukulinganisa, futhi isandla kulula ukusifaka endaweni efanele yesithwebuli, njll., Okulula ukuthi abasebenzisi bakwamukele.
2. Uhlelo lokulawula ukufinyelela kwe-IRIS
Uhlelo lokulawula ukufinyelela kwe-IRIS ukunquma ubunikazi babantu futhi banqume ukuthi ukuvula umnyango ngokuqhathanisa ukufana phakathi kwezimpawu zezithombe ze-IRIS. Inqubo ye-IRIS ukuqashelwa kwezobuchwepheshe ngokuvamile ifaka izinyathelo ezine: eyodwa ukusebenzisa imishini ethile ethile yekhamera ukudubula amehlo abantu, thola izithombe ze-IRIS futhi zihambise kwisoftware yokuthola isithombe sohlelo lokuqashelwa kwe-IRIS. Okwesibili ukuthola i-IRIS, nquma isikhundla sombuthano wangaphakathi, umbuthano wangaphandle kanye ne-quadratic curve esithombeni; Lungisa usayizi we-IRIS esithombeni ohlelweni lokubeka amapharamitha, okungukuthi, ngokwejwayelekile futhi wenze ukuthuthukiswa kwesithombe. Okwesithathu ukwamukela i-algorithm ethile ukuze akhiphe amaphuzu wesici adingekayo ekuqashelweni kwe-IRIS kusuka esithombeni se-iris futhi akwazise. Okwesine kufanele kuhambisane namakhodi wesici atholwe ngesizinda sesici nge-IRIS Image application amakhodi ku-database ngamunye ngamunye ukwahlulela noma ngabe anenhloso efanayo. Uhlelo lokulawula ukufinyelela kwe-IRIS aludingi ukuthintana ngokomzimba, linenani eliphansi lokuqashelwa okungamanga kanye nokwethenjwa okuphezulu; Kodwa-ke, kunzima ukunciphisa imishini yangaphambili yokuphela, izindleko ziphakeme, futhi kunzima ukukukhuthaza ngezinga elikhulu.
3. Uhlelo Lokulawula Ukutholwa Kwesikhathi Sokuthola Ukufinyelela
Uma kuqhathaniswa nobunye ubuchwepheshe bokubona, ubuchwepheshe bokuqashelwa kobuso bunezinzuzo ezihlukile kwinqubo yokufaka isicelo, ngokwesibonelo, kulula kakhulu kwinqubo yokuqoqwa kolwazi lwezithombe, futhi kancane kancane kube ngohlobo lwe-biometric reviem. Ukugxila kobuhlakani kanye nokuqashelwa kwephethini nakho kusetshenziswa kabanzi ezinhlelweni zokulawula ukufinyelela.
Uhlelo lokulawula ukufinyelela kwe-Face Attaction Attiction Atterance luqoqa bonke abasebenzi abavunyelwe ukufinyelela ohlelweni lokulawula ukufinyelela futhi balugcina ku-database yobuso. Lapho umuntu efinyelela ohlelweni lokulawula ukufinyelela, uhlelo lokuqashelwa kwesikhathi sokufinyelela kobuso luzoqala ukuthola imininingwane yekhamera ngekhamera, bese ufaka imininingwane eqoqiwe eqoqweni ekhompyutheni, bese yenza ukubakhona kwesikhathi sokubona ubuso. Kule nqubo, uhlelo lolu luhlulela imininingwane yezithombe ezivakashelwa ukugwema ithonya lezinkulumo, ukukhanyisa namadivayisi wokufaka emiphumeleni, kukhiphe izici zomfanekiso osusiwe, futhi ziqhathanisa imininingwane ekhishwe ngolwazi ngolwazi, futhi Qopha imiphumela yokuqashelwa. Lapho nje imininingwane yobuso engaqhathaniswa ngempumelelo ikhonjwe database, uhlelo lokulawula ukufinyelela luzothola umnyango wokuvula umnyango wekhompyutha, kanye nokusebenza kokuvumela izivakashi ukuthi zingene ngengxenye yehadiwe yohlelo lokulawula ukufinyelela; Ngaphandle kwalokho, ikhompyutha ngeke ikhiphe umyalo wokuvula umnyango, futhi ukulawulwa kokufinyelela kohlelo ngeke kuvulwe, futhi imininingwane yobuso yesivakashi izorekhodwa ukuthola umbuzo wesikhathi esizayo kanye nokugadwa.
