Uyawazi ama-algorithms amathathu wobuchwepheshe bokuqashelwa kobuso?

Ubuchwepheshe bokuqashelwa kobuso bokuqala buqoqa imininingwane yobuso, futhi uyiqhathanisa ne-database yobuso lapho umshini wokufika engenayo engena futhi uphuma ephaketheni lomgwaqo ohamba ngezinyawo. Uma ukuqhathanisa kuphumelele, umshini ababekhona uzovulwa; Uma ukuqhathanisa kwehluleka, umshini ababekhona ngeke uvule; Ukuphathwa kususelwa ekuqhathaniseni kwedatha yomsebenzisi kwimishini yokulawula yokuqashelwa kobuso, futhi ikhompyutha isetshenziswa njengethuluzi lokucubungula langemuva lokubona ngokuphelele ukuphathwa okuzenzakalelayo kwabasebenzi abangena nokuphuma endaweni yesiteshi. Ngasikhathi sinye, ngokusho kwamarekhodi okubhalisa umsebenzisi, kungakhipha ngokushesha futhi ngokuzenzakalelayo ukukhiqiza ngokuzenzakalelayo imibiko yokulawula yokulawula okungamanye amazwe okungathunyelwa ngokusho kwezimo ezahlukahlukene zokuhlunga ezifana nesikhathi, futhi kungahle kusetshenziswe njenge Uhlelo lokufunda oluzenzakalelayo lwabasebenzi bangaphakathi.

Izinhlelo zokuqashelwa abakwaBoctream Face Action Attionce zingahlelwa ngezigaba ezintathu, okungukuthi: Izindlela ezisuselwa kwizici zejometri, izindlela ezisuselwa kwizifanekiso nezindlela ezisuselwa kumamodeli.
1. Indlela esekelwe kwizici zejometri iyindlela yokuqala neyesiko, futhi imvamisa idinga ukuhlanganiswa namanye ama-algorithms ukuba nemiphumela engcono;
2. Izindlela ezisuselwa kwisifanekiso zingahlukaniswa ngezindlela ezisuselwa ekufaniseni kokuhlangana, izindlela ze-eigenface, izindlela zokubandlululwa okuqondile, izindlela zokukhomba okukodwa, izindlela zenethiwekhi ye-neural, izindlela eziguquguqukayo zokuxhuma, izindlela eziguquguqukayo zokuxhuma, izindlela ezinamandla okuxhumanisa izindlela, njll.
3. Izindlela ezisekelwe modeli zifaka izindlela ezisuselwa kumamodeli weMarkEn Hidden, amamodeli wesimo esisebenzayo, kanye namamodeli abukeka esebenzayo.
Izindlela ezenzelwe i-geomertry
Ubuso bomuntu bahlanganiswa izingxenye ezinjengemehlo, ekhaleni, umlomo nesilevu. Kuyinto ngokunembile ngenxa yokwehlukahluka okuhlukahlukene ngesimo, usayizi nokwakheka kwalezi zingxenye ububuso bomuntu obuhlukile kakhulu. Ngakho-ke, ukuchazwa kwejometri kwesimo nobudlelwano besakhiwo salezi zingxenye, kungasetshenziswa njengesici esibalulekile sokubakhona kokubonwa kobuso.
Izici ze-geometric zaqala ukusetshenziswa encazelweni nasekuqasheni kwephrofayili yobuso bomuntu. Okokuqala, amaphoyinti ambalwa aqaphelekile anqunywa ngokuya ngejika lephrofayili, kanye neqoqo lama-metric wesici sokuqashelwa, njengebanga ne-angle, asuselwa kuleli phuzu lezempi. Kuyindlela entsha kakhulu iJia et al. Belingisa isithombe sephrofayili eseceleni ngokuqagela okubalulekile eduze komugqa esithombeni esingaphezulu esimpunga.
Kusetshenziswa izici zejometri ukuze i-Frontal Face Atcheition Attenderance System ngokuvamile ikhipha izikhundla zamaphoyinti wesici esibalulekile afana namehlo, umlomo, kanye nokwenziwa kwejometri lezinto ezibalulekile njengamehlo, kepha ukusebenza kwesici se-geometric sekuhloliwe ngokuhlolwa. Cwaninga, imiphumela ayinethemba.
Indlela yethempulethi ebonakalayo ingabhekwa njengokuthuthuka kwendlela yesici sejometri. Umqondo wayo oyisisekelo ukuklama imodeli yesitho ngamapharamitha aguqukayo (okungukuthi, ithempulethi ekhubazekile), chaza umsebenzi wamandla, futhi unciphise umsebenzi wamandla ngokulungisa amapharamitha wemodeli. Amapharamitha wemodeli ngalesi sikhathi asetshenziswa njengezici zejometri zesitho.
Umqondo wale ndlela muhle kakhulu, kepha kunezinkinga ezimbili. Enye ukuthi ama-coefficients anesisindo wezindleko ezahlukahlukene kumsebenzi wamandla anganqunywa kuphela amandla, okunzima ukuwadumisa. Enye ukuthi inqubo yokwenza kahle umsebenzi wamandla idla isikhathi eside futhi kunzima ukuyisebenzisa ekusebenzeni. Ukumelwa kobuso obususelwa kupharamitha kungafinyelela incazelo yezici ezinhle zobuso, kepha kudinga ukulungiswa okuningana kokusebenza kwangaphambili nokukhethwa okuhle kwepharamitha. Ngasikhathi sinye, ukusetshenziswa kwezici ezijwayelekile ze-geometric kuchaza kuphela ukwakheka okuyisisekelo nobudlelwano bezakhiwo zezakhi, ukunganaki izici ezicashile zendawo, okuholela ekulahlekelweni kwengxenye yolwazi, okulungele ukuhlukaniswa okunzima
