Ikhowudi yomthombo wenkqubo yokufunda yomatshini wePIXIE ivuliwe, ikuvumela ukuba wenze iimodeli ze-3D kunye nee-avatars ezinobomi bomzimba womntu kwifoto enye. Ubume bobuso obuyinyani kunye nempahla yokunxiba eyahlukileyo kuleyo iboniswe kwifoto yokuqala inokudityaniswa kwimodeli eyisiphumo. Inkqubo ingasetyenziswa, umzekelo, ukunikezela ukusuka kwindawo eyahlukileyo, ukudala i-animation, ukwakha kwakhona umzimba ngokusekelwe kwimilo yobuso, kunye nokuvelisa imodeli ye-3D yeminwe. Ikhowudi ibhalwe kwiPython isebenzisa isakhelo sePytorch kwaye ihanjiswa phantsi kwelayisenisi yokusetyenziswa okungeyontengiso kuphela.
Kuxelwe ukuba, xa kuthelekiswa neeprojekthi ezifanayo, i-PIXIE ikuvumela ukuba uphinde uhlaziye ngokuchanekileyo i-contours yomzimba, ekuqaleni ifihlwe yimpahla kwifoto, imilo yobuso kunye nokuma kwamalungu ezandla. Indlela isekelwe ekusebenziseni inethiwekhi ye-neural, ekhupha imilinganiselo yobuso, umzimba kunye nezandla kumfanekiso we-pixel. Umsebenzi womnatha we-neural ulungelelaniswa ngumlawuli okhethekileyo, othi, ngokusekelwe kuhlalutyo lokukhanya, wongeza ulwazi malunga ne-weighting coefficients yamalungu ahlukeneyo omzimba ukuba angabandakanyi ukufunyanwa kwezinto ezingezona ezendalo. Xa udala imodeli, ukungafani kwe-anatomical phakathi komzimba wesilisa nowesifazana, iiparitha zokuma, ukukhanya, ukubonakalisa umphezulu kunye nokujikeleza kobuso kwinqwelo-moya ye-three-dimensional ithathelwa ingqalelo.
Iimpawu zePIXIE:
- Ukwakhiwa kwakhona kwemodeli yomzimba we-3D, kunye nolwazi malunga ne-pose, isikhundla sesandla kunye nembonakalo yobuso, igcinwa njengeseti yeeparamitha ze-SMPL-X, ezinokuthi zisetyenziswe kamva kwi-Blender modeling system nge-plugin.
- Ukusuka kwifoto, ulwazi olucacileyo luchongiwe malunga nokuma kunye nokubonakaliswa kobuso, kunye neempawu zayo, ezifana nobukho bemibimbi (inkqubo yokufunda umatshini weDECA, ephuhliswe ngababhali abafanayo, isetyenziselwa ukwakha imodeli yentloko) .
- Xa uvelisa ukuthungwa kobuso, i-albedo yento iqikelelwa.
- Imodeli yomzimba eyakhiweyo inokudlalwa okanye iboniswe ngendlela eyahlukileyo.
- Inkxaso yokwakha imodeli kwiifoto eziqhelekileyo zomntu kwiimeko zendalo. I-PIXIE yenza umsebenzi omhle wokubona iindlela ezahlukeneyo zokumisa, iimeko zokukhanyisa, kunye nokuthintela ukubonakala kweendawo zento.
- Ukusebenza okuphezulu, kukulungele ukuqhutyelwa okuguquguqukayo kwemifanekiso yekhamera.
