Ndiye ndixubusha ngokuphindaphindiweyo ngamacandelo anokufakela abalinganiswa. Kubafundi abatsha, ndingathanda ukuphinda kwakhona apha ngcaciso encinane kwinqaku ekhethekileyo enikezelwe kwesi sihloko. Kungenxa yokuba ukuba ulandela iindaba zemihla ngemihla, kubaluleke kakhulu ukuba uqhelane nale ngongoma, kuba uya kubona ukuba ziphi iindlela ezikhoyo zokudlala abantu. Kulula kakhulu.

I-Deepfakes zenziwe ngeGAN (i-Generative Adversarial Networks)) zobugcisa. Le yesoftware ehlakaniphile eyenza ukuba, ngokusekelwe kwiinkqubo ezininzi ze-AI kwinethiwekhi, idala abalinganiswa ngaphandle kwento. I-A yiNgesi yesiNgesi soBuchule; yintoni emele ingqiqo yolwazi. Enye inethiwekhi ye-AI ivavanya imifanekiso eyenziwe yintanethi yokuqala kwaye iyayivuma okanye iyayivuma. Ngokwenza oku kumjikelezo, abalinganiswa banokubheka ngokunyanisekileyo kwisinyathelo ngasinye, ukuze ekugqibeleni unikeze abantu abaqhelanisiweyo ababukeka njengabantu abaqhelekileyo bemihla ngemihla (onokuhlangana nabo kwisitalato). Ukuba ufuna ukwazi kakuhle indlela oku kusebenza ngayo, qaleni ukhangele ividiyo elandelayo ngeNVIDIA (umenzi wekhadi elibonisa imifanekiso yePCs).

Akukona nje kuphela luncedo ukwazi ukuba le nkqubo ikhona, kodwa kwakhona indlela umlinganiselo onzulu ongasetyenziswa ngayo, umzekelo, iividiyo okanye ukuvelisa iiprojethi zeendaba zoluntu (kubandakanywa nembali yonke; kuquka iifoto kunye namavidiyo kunye nokuthanda kwabanye ukunyusa iingxelo zeendaba zoluntu). Ngokomzekelo, iingxoxo zeendaba zoluntu zinokugcinwa lula kwi-intanethi "ngabasebenzi basekhaya" okanye abasebenzi be-arhente ye-telemarketing, umzekelo, apho abalinganiswa onokuxoxa ngabo banokufihla emva kweso sithuba esicacileyo (kunye nabaxhasi babo abaxhamli nabo bazaliswa ngeprofayili enzulu). Bayakwazi ukuhlasela abantu kwixesha labo kwiingxoxo ukwenzela ukuba bathuthele phakathi kwabantu ngendlela ethile.

Makhe sijonge kuzo zonke iindlela zokufaka izicelo, kodwa ngaphambi kokuba siqale, kunceda ukwazi ukuba umdlalo wezemidlalo kunye nefilimu, kodwa nabavelisi beTV, baye bafumana iindlela ezinjalo ixesha elide. Nangona kunjalo, umsebenzi ulungelelanise kangangokuba ungakwenza ngokwakho kwi-PC-garden-nasekhitini yekhaya.

Xa uPaul Walker efa phakathi kwe-7 yokurekhoda okukhawulezayo kunye nefuthe, inkampani yeWeta Digital ibizelwe ekugqityeni inguqulo yefilimu kaPaul Walker. Ngokusekelwe kwiinkqubo ezinjengeemifanekiso ezindala, izicwangciso zomzimba zabazalwana bakaPawulos kunye nokukhangela intloko kaPawulos, iWeta Digital yazisa uPaul Walker ebomini. Ividiyo engezansi inikeza isishwankathelo sendlela oku kusebenza ngayo.

I-3D inkqubo yokuthunyiswa kwesimo sokunyuswa kwenkqubela iye yahlala iminyaka kangangokuba abadlali bembatha izikhwama ukurekhoda ukunyakaza kwabo baze banqamle iimpawu ezidalwe ngamanani ngeCGI. Oku kufaniswa nokusetyenziswa okwenziwa nguPaul Walker, kuphela ngabadlali abaphilayo bembethe i-suit capture capture. Olu hlobo lusetyenziswa kubantu abano-bhajethi ephantsi (jonga ividiyo engezantsi), kodwa umzekelo omhle wefilimu apho le ndlela sele isetyenzisiwe yi-Avatar Avatar esuka kwi-2009 (jonga apha).

I-NVIDIA sele sele ibambelele ekusebenziseni kwezi zixhobo kunye ne-teknoloji yeCGI, kuba isebenzisa amanethiwekhi e-neural ukuqeqesha isofthiwe. Enyanisweni, le yindlela efanayo emva kobuso obunzulu. I-NVIDIA ngoku ayikwazi nje ukuvelisa ubuso obungabikho, kodwa inokuyidlulisela idolophu ngekhamera kwaye uyibuyisele kwindawo yebusika (ngexesha langempela). Amasu anjalo angasetyenziselwa ukuqeqesha isofthiwe ye-AI yemoto yokuzilawula ekuguqukeleni izimo zemozulu, kodwa zingasetyenziselwa ukwenza i-suit capture capture ifanelekile. Ikhamera ye-GoPro elula okanye ikhamera yewebhu iyanele. Khangela i-1: 03 min. Kwividiyo engezantsi ukubona ukuba kusebenza njani.

Ngoku ungacinga ukuba ithuba lokwenza oku ngexesha langempela alikho. Cinga kwakhona. Sivele sibonile ngasentla ukuba kunokwenzeka ukudala abantu abangabikhoyo ngeNgcaciso yokuThuthuka kweeNethiwekhi. Ngoku siyazi ukuba zombini ummandla wasezidolophini kunye nomlinganisi unokuveliswa ngeenethiwekhi zomnxeba. Umbuzo kukuba ingaba kwenzekayo ngexesha langempela. Yilapho i-teknoloji ye-realtime time-reenactment ifika. Oku kuye kwajikeleza i-PC elula ekhaya ngonyaka we-2015 (jonga ividiyo engezansi).

Konke kukho, ngoko sinako ukuthetha ukuba kunokwenzeka ukuba iminyaka ivelise amavidiyo angcolileyo. Nangona kunjalo, iteknoloji ngoku sele ilula kakhulu kunye nokuvela kweeNethiwekhi zokuThuthukiswa kweziNtshukumo, iiNethwekhi zokunxibelelana kunye nexesha eliqhelekileyo lokubonakalisa ubuso, ukuba unokwenza imbali yonke yomntu ongekhoyo kumcimbi wemizuzu, udliwano-ndlebe lwaloo mntu engekhoyo unokwenza nayiphi na imeko evela kuyo nayiphina imbonakalo yekhamera kunye nayiphi na imeko yemozulu.

Ziziphi iziphumo zolu? Ukuqala, ungatsho ukuba awukwazi ukuthemba i-100% iminyaka. Jonga apha Ubungakanani ubuchule beCGI obuye busetyenziswa kwishishini lefilimu. Nangona kunjalo, okwangoku kulula kakhulu ukuba nabani na uhlahlo lwabiwo-mali bamawaka angamawaka angakwazi ukwenza oku. Ukuba sicinga ukuba amajelo alungileyo, ngoko sinokucinga ukuba abazange basebenzise iindlela ezinjalo kwiminyaka. Nangona kunjalo, ukuba sicinga ukuba oorhulumente basebenzelana nokusebenza kwengqondo ukuba bazise abantu ngendlela yokumkeleka kwemithetho emitsha neyomeleleyo, ngoko simele siqaphele ukuba iminyaka kwiminyaka engekho nto ihleli ngendlela yokuvelisa iindaba eziyinyani. Ngaloo mxholo kunomdla kakhulu ukwazi ukuba i-arhente yeendaba ephakamileyo yelizwe (i-Algemeen Nederlands Persbureau; i-ANP enezantsi) isezandleni zomvelisi weTV (ngubani naye unesigidigidi). Kufuneka sibe mkhulu kangakanani ukuba siqiniseke ukuba ezi zinto zingasetyenziswanga iminyaka?

Kubonakala ngathi amajelo akhangele ukuvala ukuvuza okuthi uMartin Vrijland utshitshise phantsi kwinqanawa enkulu yeendaba. Kwiminyaka emininzi ngoku, ndichazile indlela abeendaba abangasebenzisa ngayo imifanekiso. Ngoko ke uJort Kelder no-Alexander Klöpping bavunyelwe kwinkqubo yeKelder & Klöpping TV bonise ziphi izinto ezinzulu. Kwakhona inomathotholo Umnqophiso wezithombe I-BNR Nieuwsradio (abaphathi beengcinga) bathetha ngoku kutshanje oko ndibhalile malunga nokude. Kucacile ukuba uloyiko luhlala lubonakala kwaye ukuba abenzi benkqubo mabazame ukugcina umbukeli kunye nomphulaphuli. Kufuneka uqhubeke uthembela kumajelo aseburhulumenteni nakwintando yesininzi, kuba akukho nto ibhetele kunokuba isixuku sivukele (ukuthetha ngamazwi aseJort phantsi).

Ngokuqinisekileyo "isisombululo" kukho konke okokuba oorhulumente kunye nenkampani yezobuchwepheshe baya kuzama ukongeza uhlobo lweetermarket kumafilimu, ukwenzela ukuba bahlolwe ukuba baqiniseke. Umbuzo wodwa kukuba ukuba oorhulumente ngokwabo basebenzisa iindaba eziyinyani ngeminyaka ukuba baphucule umthetho kwaye badlale abantu nokuba ingaba i-watermark inokuthenjwa. Ngaba i-butcher iya kukwala inyama yakhe? Hayi, akunjalo. Zonke iindaba ezivela kuJohn de Mol, NOS, De Telegraaf njalonjalo ziye zithembeke ngokupheleleyo kwaye zinyaniseka! Isiqhamo. Ngaba ucinga ukuba uYohn de Mol uza kubonakala kwiTV namhlanje okanye ngomso athi: "Siyaxolisa, bafazi kunye nenceba, ndenze iindaba zobuxoki kunye nazo zonke ii-studio ze-TV kunye nesofthiwe enginayo. Ndikunikezele ngeendaba ezikhohlisayo kwaye ndadlala kunye nokusebenza kwengqondo kwindleko yerhafu yerhafu kwaye ndagcwalisa iingxowa zam"? Hayi, akunjalo. Kwaye kufuneka ube nokholo kumajelo aseburhulumenteni nakulo rhulumente, kuba ngubani omnye onokumthemba? Funda apha...

Unakho ukufaka izicelo ezinzulu:

  1. ukunyusa iingxelo zeendaba zoluntu
  2. iifoto kunye namavidiyo avela kwixesha elidlulileyo kuquka nabentsapho kunye nabahlobo
  3. buxubusha udliwano-ndlebe nomntu ongekho
  4. imifanekiso kwiinkhamera zokhuseleko
  5. ividiyo njengobungqina kwiindaba (iimveliso zeendaba ezikhohlisayo)
  6. njalo njalo

    Iinkokeli zale polaneti zisasebenzisa iindlela ezifanayo. Ngokubhekiselele kwiteknoloji, bahlala behlala kunye namaxesha. Kwixesha elidlulileyo unako ukuqhuba iindibano ezipheleleyo zihlambulule kunye nomntu ongekho. Baye bahlala beyinyathelo elilodwa phambi kwethu ngokulawula imbali ngoncedo lweencwadi zeencwadi.

    Kwixesha elidlulileyo kwakukho noMartin owakhankanya kubantu ukuba bayakhohliswa.

    Into embi kukuba abantu namhlanje bacinga ukuba banengqiqo kunabo bethu ngaphambili. Andiyicingi into yokuba ishintshile, sisengamakhoboka esisebenza nzima nzima ukuluma kunye nokusela.

    Babesethetha ukuba "akufanele ukholelwe konke abakushoyo"

    Namhlanje sithi "akufanele ukholwe yonke into oyibonayo"
