Icyo "AI Green Screen" bivuze (n'impamvu atari "gukuraho inyuma" gusa) 🤖✨

Ecran gakondo y'icyatsi kibisi ikoresha inyuma y'icyatsi kibisi + chroma keying.

Ubusanzwe ecran y'icyatsi kibisi ya AI ni ugutandukanya ibice (icyitegererezo gihanura pikseli zigomba kuba iz' "umuntu" ugereranije n' "atari umuntu"), rimwe na rimwe no guhurirana (icyitegererezo gipima ubwisanzure busesuye ku tuntu duto nk'umusatsi, kubura uko ibintu bigenda, impande z'ikirahure, nibindi). Gutandukanya ibice ni "ugukata cyane." Gutandukanya ibice ni igice "ibi bisa n'ubuzima busanzwe". Munsi y'ifi, uburyo bwinshi bugezweho bwubatse ku bitekerezo byo gutandukanya ibice aho sisitemu ikora agapfukamunwa ka pikseli ku kintu / umuntu [1].

Ubusanzwe uzabona ecran y'icyatsi kibisi ya AI igaragara nka:

  • y'amafoto cyangwa videwo rimwe gusa

  • Gukoresha rotoscoping ya AI ikurikirana amashusho (ikoresha ikoranabuhanga, ariko muri rusange "rotoscoping")

  • Gusimbuza inyuma imbonankubone guhamagara no guhamagara kuri interineti 🎥

  • Ishusho y'inyuma ikora ishusho nshya inyuma yawe 🌄

  • Gupfuka ikintu ku rwego rwo hejuru aho bigerageza gutandukanya umusatsi, amaboko, ibikoresho… rimwe na rimwe… mu buryo

Intsinzi ikomeye ni uburyo bworoshye. Ingaruka nini ni ubuziranenge. Ubuhanga bwo gukora imibonano mpuzabitsina (AI) buratekereza - kandi rimwe na rimwe butekereza nk'aho bwambaye ibyuma bipfundikiye mu ifuru.

Uburyo busanzwe ni: igihe nyacyo cyo kwihuta, guhindura no gukosora ku gihe ikintu cyose gihuye n'umukiriya.

Nigute nakora umusatsi usa neza nkoresheje ecran y'icyatsi kibisi ya AI (kandi atari nk'aho ushonga)?

Umusatsi niho agapfukamunwa gakunze kuvunika mbere, bityo rero teganya kunonosora. Shaka "inkombe nto" cyangwa uburyo bwo kugenzura imisatsi, kandi ukoreshe ingano nto y'amababa hamwe n'ubwitonzi bwo kwagura/kugabanya kugira ngo umusatsi udahinduka ubonerana. Niba igikoresho gitanga uburyo bwo gukuraho ibara ry'inkombe, gikoreshe kugira ngo umusatsi udafata ibara ry'inyuma.

Kuki amaboko, ingendo zihuse, n'ibintu bito bikomeza gusibangana mu bice bya AI?

Gutandukanya ibice birwana no kubura imiterere y'ishusho n'utundi duce tw'inyuma nk'intoki, amaboko ya mikoro, n'amadirishya y'indorerwamo, bityo igishushanyo gishobora kubigabanya cyangwa kikazima. Kongera ubushobozi bwo guhagarara cyangwa gushyiraho uburyo bwo guhuza ibintu bishobora kugabanya urusaku rw'amashusho hagati ya 1 na 2, kandi kwagura agapfukamunwa gato bishobora gufasha amaboko kuguma ameze neza. Iyo bikinaniwe, gusiga irangi/uburoso n'intoki muri utwo duce akenshi ni byo bikemura vuba.

Nigute nakora inyuma yasimbuwe igaragara nk'iy'ukuri aho kuba "yashyizwemo"?

Ibisubizo byinshi "by'impimbano" bituruka ku bibazo bidahuye, ntabwo ari ibibazo byo guhisha. Huza urumuri, itandukaniro, n'ubushyuhe bw'amabara hagati yawe n'inyuma, kandi wirinde inyuma hatandukanye cyane. Ongeraho hasi nk'igicucu cyoroshye, akantu gato k'inyuma, cyangwa urusaku ruhoraho mu byiciro kugira ngo umuntu uri ku ifoto yawe n'inyuma yumve ko bisangiye kamera imwe.

Nigute wakoresha AI Green Screen mu guhamagara kuri Zoom cyangwa kuri streaming nta glitch halos?

Umucyo ni ingenzi kurusha uko abantu babitekereza: urumuri rukomeye, ndetse n'imbere hamwe n'inyuma isanzwe bigabanya urujijo mu gupfuka. Iha intera uvuye ku rukuta kugira ngo utandukanye, kandi wirinde amabara y'imyenda ahurirana n'inyuma yawe. Niba webcam yawe isa n'aho "imeze nabi," kugabanya ubukana bishobora gufasha, kuko impande zishyushye cyane zishobora gutera guhindagurika no guhindagurika mu buryo bwihuse.

Ni iyihe format nziza yo kohereza hanze amashusho ya AI green screen hamwe n'uburyo bworoshye bwo kuyakoresha?

Niba ukeneye inyuma ibonerana kugira ngo wongere ukoreshe cyangwa uhuze, uzakenera kohereza hanze ishyigikira umuyoboro wa alpha. Imikorere myinshi ikoresha Apple ProRes 4444 kugira ngo ubone alpha nziza, cyane cyane iyo uteganya kongera gukora compositing nyuma. Niba udakeneye transparency, kohereza hanze videwo ya nyuma ifite inyuma nshya biroroshye kandi birinda ibibazo byo guhuza.

Ni ubuhe buryo bwo "kuvangavanga" iyo ukanze rimwe gusa ecran y'icyatsi kibisi ya AI idasukuye bihagije?

Koresha agace ka AI nk'ishingiro ryawe, hanyuma ushyiremo udushya dufatika aho kongera gutangira. Ongeraho agace k'imyanda gafite ibara ryihuse kugira ngo ukureho ahantu hagaragara hafite ikibazo, usige irangi ku bintu bito bicika, kandi ukoreshe ibikoresho by'igihe gito/bihoraho kugira ngo woroshye urumuri ku mashusho. Ibikoresho nka After Effects (Roto Brush/Refine Matte) cyangwa DaVinci Resolve (Magic Mask) akenshi birakora neza hano kuko bihuza AI n'uburyo nyabwo bwo kugenzura.
