Uyawazi ama-algorithms amathathu wobuchwepheshe bokuqashelwa kobuso?

Ubuchwepheshe bokuqashelwa kobuso Bona kuqala ukuqoqa imininingwane yobuso, futhi uyiqhathanisa ne-database yobuso lapho ungena futhi ukhipha isango lendima yabahamba ngezinyawo. Uma ukuqhathanisa kuphumelele, kuvulwa isango. Ukuphathwa kususelwa ekuqhathaniseni kwedatha yomsebenzisi kwimishini yokulawula yokuqashelwa kobuso, futhi ikhompyutha isetshenziswa njengethuluzi lokucubungula langemuva ukuze uqaphele ngokuzenzakalela ukuphathwa okuzenzakalelayo kwezisebenzi ezingena nokuphuma endaweni yesiteshi, naku Ngokufanayo, ingaqhutshwa ngokushesha futhi ngokuzenzakalelayo ngokusho kwerekhodi lokubhalisa umsebenzisi. Amarekhodi okulawula ukufinyelela nemibiko kungathunyelwa ngokusho kwezimo ezahlukahlukene zokuhlunga ezinjengesikhathi esidingwa ngabasebenzisi, okulungele abaphathi ukuthi babuze amarekhodi, futhi nakho kungasetshenziswa njengohlelo 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 ukufeza imiphumela 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.
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 zejometri kuqala zisetshenziselwa ukuchaza nokubona iphrofayili yobuso bomuntu. Okokuqala, amaphoyinti ambalwa ahlelekile anqunywa ngokuya ngejika lephrofayili, kanye neqoqo lama-metric wesici sokuqashelwa okufana nebanga, i-angle, njll. Asuselwa kuleli phuzu lezempi. Jia et al. Ukuqagela okuhlanganisiwe eduze komugqa kumephu ye-degree kuyindlela kakhulu yenoveli yokulingisa imephu yephrofayili eseceleni.
Kusetshenziswa izici zejometri yokuqashelwa kobuso bangaphambili kanye nezinhlelo zababekhona ngokuvamile zikhipha izikhundla zamaphoyinti abalulekile afana namehlo, umlomo, kanye nobumba bejometri lezinto ezibalulekile, kepha ukunemba kwesici sejometri sekukhona ihlolwe ihlolwe. Cwaninga, imiphumela ayinethemba.
Indlela yethempulethi ebonakalayo ingabhekwa njengokuthuthuka kwendlela yesici sejometri. Umqondo wayo oyisisekelo yile: Design imodeli ye-Organ enamapharamitha aguqukayo, chaza umsebenzi wamandla, futhi unciphise umsebenzi wamandla ngokulungisa amapharamitha wemodeli. Ngalesi sikhathi, amapharamitha wemodeli anjengezici zejometri zesitho.
Umqondo wale ndlela muhle kakhulu, kepha kunezinkinga ezimbili. Enye ukuthi ama-coefficients anesisindo wezindleko ezahlukahlukene emsebenzini wamandla anganqunywa kuphela ngesipiliyoni, okunzima ukukhuthaza. Okunye ukuthi inqubo yokusebenza kahle kwamandla idla isikhathi esiningi futhi kunzima ukuyisebenzisa ekusebenzeni. Ukumelwa kobuso kungafinyelela incazelo yezici ezinhle zobuso, kepha kudinga ukukhethwa okuningi kwangaphambi kokucubungula kanye nokukhetha okuhle. Ngasikhathi sinye, ukusetshenziswa kwezici ezijwayelekile ze-geometric kuchaza kuphela ukwakheka okuyisisekelo nobudlelwano bezinhlaka zezakhiwo, ukungazinaki izici ezicashile zendawo. Kubangela ukulahleka kwengxenye yolwazi, olufanele ngokwengeziwe ukuhlukaniswa okunzima, futhi ubuchwepheshe obukhona bokutholwa kwesici bukhona ekuhlangabezaneni nezidingo ngokuya ngokusebenza kahle, kanye nenani lokubalwa likhulu.
