Gutera imbere mu buryo bwa AI bikorwa bite?

Igisubizo kigufi: Gupima ubuziranenge bw'ubwenge (AI) bikoresha uburyo bwo gutoza icyitegererezo ku mashusho afite ubushobozi bwo hasi n'ubunini, hanyuma bigakoreshwa mu guhanura pixel z'inyongera zizewe mu gihe cyo kongera ubushobozi. Niba icyitegererezo cyabonye imiterere cyangwa amasura asa mu myitozo, gishobora kongeramo ibisobanuro bifatika; bitabaye ibyo, gishobora "guhindura" ibintu nk'urumuri, uruhu rw'umutuku, cyangwa urumuri muri videwo. 

Ibintu by'ingenzi byakunzwe:

Iteganyagihe: Icyitegererezo gitanga ibisobanuro bifatika, ntabwo ari ukwiyubaka burundu kw'ukuri.

Guhitamo icyitegererezo: CNN zikunze kuba zihamye; GAN zishobora kugaragara neza ariko zigashobora guhanga udushya.

Igenzura ry'ibintu byakozwe: Reba isura y'inyuma, imiterere isubirwamo, "inyuguti hafi ya zose", n'amasura asa n'ay'iplastike.

Guhagarara kw'amashusho: Koresha uburyo bw'igihe runaka cyangwa uzabona uburyo bwo gushyuha no kunyerera kw'amashusho kuva kuri frame kugera kuri frame.

Gukoresha neza: Niba ukuri ari ngombwa, garagaza uburyo ikoreshwa kandi ufate ibyavuye mu bushakashatsi nk'icyitegererezo.

Ushobora kuba warabibonye: ishusho ntoya, ishaje ihinduka ikintu gisobanutse neza ku buryo cyacapwa, gishyirwa ahagaragara cyangwa kigashyirwa mu kiganiro nta gushidikanywaho. Bisa n'uburiganya. Kandi - mu buryo bwiza - ni nk'aho ari 😅

Rero, Uburyo AI Upscaling ikora bushingira ku kintu cyihariye kuruta "mudasobwa yongera ibisobanuro" (ikoresha intoki) kandi hafi ya "icyitegererezo gihanura imiterere ishoboka ifite ubushobozi bwo hejuru bushingiye ku miterere yize mu ngero nyinshi" (Deep Learning for Image Super-resolution: A Survey). Iyo ntambwe yo guhanura ni umukino wose - niyo mpamvu AI upscaling ishobora kugaragara neza cyane… cyangwa se ikoze muri pulasitiki… cyangwa nk'aho injangwe yawe yakuze ifite ubwanwa bw'inyongera.

Ingingo ushobora gukunda gusoma nyuma y'iyi:

Uburyo AI Upscaling ikora: igitekerezo cy'ingenzi, mu magambo ya buri munsi 🧩

Gushyira hejuru bivuze kongera ubushobozi bwo kureba: pikseli nyinshi, ishusho nini. Gushyira hejuru mu buryo busanzwe (nk'ibice bibiri) mu buryo busanzwe bigabanya pikseli kandi bigahindura ihinduka (interpolation ya Bicubic). Ni byiza, ariko ntibishobora guhanga bishya - bihinduranya gusa.

Kuzamura ubuhanga bwa AI bigerageza ikintu gikomeye kurushaho (cyangwa "super-resolution" mu isi y'ubushakashatsi) (Deep Learning for Image Super-resolution: A Survey):

• Ireba uburyo bwo gushyiramo amakuru make

• Amenya imiterere (inkombe, imiterere, imiterere yo mu maso, imitako y'inyandiko, ubudodo bw'imyenda…)

• Ihanura uko verisiyo ifite resitora nyinshi ikwiye kumera

• Ikora amakuru y'inyongera ya pixel ajyanye n'iyo miterere

Ntabwo ari "kugarura ukuri neza," nko "gutekereza ibintu byizewe cyane" (Image Super-Resolution Using Deep Convolutional Networks (SRCNN)). Niba ibyo bisa nkaho biteye amakenga, ntabwo wibeshye - ariko nanone niyo mpamvu bikora neza cyane 😄

Kandi yego, ibi bivuze ko kongera ubushobozi bwa AI mu buryo bw'ibanze ari ugusuzuma ibintu bitagaragara… ariko mu buryo butanga umusaruro kandi burangwa no kubahiriza pixel.

Imiryango y'ingenzi y'icyitegererezo ikoreshwa mu kongera ubushobozi bwa AI (n'impamvu bumva batandukanye) 🤖📚

1) Uburyo bwo gukora ibintu bushingiye kuri CNN (uburyo busanzwe bwo gukora ibintu)

Imiyoboro y'ubwonko ya Convolutional ni myiza cyane ku miterere y'aho umuntu aherereye: impande, imiterere, imiterere mito (Image Super-Resolution Using Deep Convolutional Networks (SRCNN)).

• Ibyiza: byihuse, bihamye, ibintu bike bitunguranye

• Ibibi: bishobora kugaragara nk'aho "byatunganyijwe" gato iyo bisunitswe cyane

2) Gutera hejuru hakoreshejwe GAN (uburyo bwa ESRGAN) 🎭

GANs (Generative Adversarial Networks) zitoza icyuma gitanga amashusho kugira ngo gikore amashusho afite ubuziranenge buhanitse umuntu utandukanya abandi adashobora gutandukanya n'ay'ukuri (Generative Adversarial Networks).

• Ibyiza: imiterere itangaje, imiterere itangaje

• Ibibi: bashobora guhanga ibintu birambuye bitariho - rimwe na rimwe bitari byo, rimwe na rimwe bidasanzwe (SRGAN, ESRGAN)

GAN ishobora kuguha ubwo bwenge butangaje. Ishobora kandi guha umuntu ufotora ifoto yawe indorerwamo nyinshi. Rero… hitamo intambara zawe 😬

3) Kuzamura urwego rw'impinduka (ikarita y'ubuhanga) 🌫️➡️🖼️

Uburyo bwo gukwirakwiza ibintu bugabanya urusaku intambwe ku yindi kandi bushobora kuyoborwa kugira ngo butange imiterere irambuye (SR3).

• Ibyiza: ishobora kuba nziza cyane mu gusobanura ibintu birambuye, cyane cyane ku mirimo yo guhanga

• Ibibi: bishobora kuva ku mwirondoro/imiterere y'umwimerere iyo imiterere iteye ubwoba (SR3)

Aha niho "kongera ubushobozi" bitangira kuvanga no "kongera ubushobozi bwo gutekereza." Hari igihe ibyo ari byo wifuza. Hari igihe atari byo.

4) Kongera ubwiza bwa videwo mu buryo bw'igihe 🎞️

Gukoresha videwo mu kongera ubushobozi bwo gukora amashusho akenshi byongera uburyo bwo kumenya uko ibintu bigenda:

• Ikoresha amafuremu yegeranye kugira ngo ihamye amakuru arambuye (BasicVSR (CVPR 2021))

• Agerageza kwirinda ibintu bihindagurika kandi bikurura

• Akenshi bihuza super-resolution na denoise na deinterlacing (Topaz Video)

Niba kongera ubwiza bw'ishusho ari nko kugarura ishusho imwe, kongera ubwiza bw'amashusho ni nko kugarura igitabo cy'ishusho utiriwe uhindura izuru ry'umuntu buri rupapuro. Ibyo biragoye kurusha uko bisa.

Impamvu rimwe na rimwe kongera ubushobozi bwa AI bisa n'aho ari impimbano (n'uko wabibona) 👀🚩

Kuzamura imiterere y'ubuhanga bwa gihanga (AI) birananirwa kumenyekana. Umaze kumenya imiterere, uzabona ahantu hose, nko kugura imodoka nshya hanyuma ukumva iyo moderi kuri buri muhanda 😵💫

Ibivugwa bisanzwe:

• Shyira uruhu rwa shashi ku maso (urusaku rwinshi cyane + koroshya)

• Utuzu tw’imbere tw’impande (ahantu hazwi cyane nk’aho hakozwe cyane) (Interpolation ya Bicubic)

• Imiterere isubirwamo (inkuta z'amatafari ziba ibishushanyo byo gukoporora no gupakira)

• Ishusho ntoya iteye ubwoba ivuga "algorithm"

• Guhindura inyandiko aho inyuguti ziba hafi y'inyuguti (ubwoko bubi cyane)

• Uburyo bwo guhindura ibintu burambuye aho ibintu bito bihinduka mu buryo butunguranye, cyane cyane mu mikorere y'ikwirakwizwa (SR3)

Igice kigoye: hari igihe ibi bihangano bisa "byiza" iyo ubyitegereje. Ubwonko bwawe bukunda ubuhanga. Ariko nyuma y'akanya gato, wumva ... nta cyo ushoboye.

Uburyo bwiza ni ugukora zoom out no kureba niba isa neza ku ntera isanzwe yo kureba. Niba isa neza gusa kuri zoom ya 400%, ntabwo ari intsinzi, ni ibintu byo kwishimisha 😅

• Amakuru yahujwe (inyongera ifite ubushobozi bwo hasi, intego ifite ubushobozi bwo hejuru) (Image Super-Resolution ikoresha Deep Convolutional Networks (SRCNN))

• Imikorere y'igihombo ihana ivugurura ritari ryo (SRGAN)

Ubwoko busanzwe bw'igihombo:

• Gutakaza pixel (L1/L2)
  Bitera imbaraga gukora neza. Bishobora gutanga ibisubizo byoroshye gato.

• Kubura ubushobozi bwo kubona
  bigereranya ibintu byimbitse (nk'aho "ibi bisa ") aho kugereranya pixels nyazo (Kubura ubushobozi bwo kubona (Johnson et al., 2016)).

• Igihombo cy’abahanganye (GAN)
  Gitera imbaraga mu kuba impamo, rimwe na rimwe ku giciro cyo gukoresha ukuri kw’ibintu uko biri (SRGAN, Generative Adversarial Networks).

Hariho intambara ihoraho:

• Bigire ukuri ku bya mbere
  vs.

• Bikore biryoshye cyane mu maso

Ibikoresho bitandukanye bihurira ahantu hatandukanye kuri ubwo buryo. Kandi ushobora guhitamo kimwe bitewe niba urimo gusubiza amafoto y'umuryango cyangwa gutegura poster aho "ubwiza" ari ingenzi kuruta ukuri kw'ubucamanza.

Imikorere ifatika: amafoto, scan za kera, anime, na videwo 📸🧾🎥

Amafoto (amafoto, imiterere y'ahantu nyaburanga, amafoto y'ibicuruzwa)

Ubusanzwe, uburyo bwiza bwo gukora ni ubu:

• Uruhu rworoheje mbere na mbere (niba bikenewe)

• Ifite imiterere ihamye kandi ihamye

• Ongeramo ibinyampeke niba ibintu bisa neza cyane (yego, mu by'ukuri)

Ibinyampeke ni nk'umunyu. Ifunguro rya nimugoroba rirenze urugero, ariko nta na kimwe gishobora kuryoha gato 🍟

Guskana kwa kera n'amashusho acucitse cyane

Ibi biragoye kuko moderi ishobora gufata ibice byo gukandagira nk' "imiterere."
Gerageza:

• Gukuraho cyangwa gukuraho ibisasu byakozwe n'abantu

• Hanyuma igiciro cyo hejuru

• Hanyuma gutyaza urumuri (ntabwo ari byinshi cyane… ndabizi, buri wese arabivuga, ariko aracyabivuga)

Anime n'ubuhanzi bw'imirongo

Ubuhanzi bw'umurongo bugira akamaro muri:

• Ibyuma bibungabunga impande zisukuye

• Kugabanya imiterere y'ibintu bidasanzwe
  Gutera imiterere ya Anime bikunze kugaragara neza kuko imiterere yayo yoroshye kandi ihoraho. (Amahirwe ni uko).

Videwo

Videwo yongeraho intambwe z'inyongera:

• Urusaku

• Deinterlace (ku masoko amwe n'amwe)

• Igipimo cyo hejuru

• Gutunganya cyangwa gushimangira igihe gito (BasicVSR (CVPR 2021))

• Gusubiramo ibinyampeke ku buryo bworoshye kugira ngo bihuzwe

Imyitwarire myiza, ukuri, n'ikibazo kitoroshye cy' "ukuri" 🧭😬

Kongera ubushobozi bwa AI bigabanya umurongo:

• Gusubiza ibintu mu buryo bushya bisobanura kugarura ibyari bihari

• Kongera bivuze kongeramo ibitari

Ku mafoto y'umuntu ku giti cye, akenshi biba byiza (kandi ni byiza). Ku bijyanye n'itangazamakuru, ibimenyetso by'amategeko, amashusho y'ubuvuzi, cyangwa ikindi kintu cyose aho ukuri ari ngombwa… ugomba kwitonda (OSAC/NIST: Ubuyobozi Busanzwe bwo Gucunga Ishusho y'Ikoranabuhanga, Amabwiriza ya SWGDE yo Gusesengura Ishusho y'Ikoranabuhanga).

Itegeko ryoroshye:

• Niba hari ingaruka nyinshi, fata ko kongera ikoranabuhanga rya AI ari illustrative, atari ukugaragaza ko ari ingenzi.

Nanone, gutangaza amakuru ni ingenzi mu bijyanye n'umwuga. Si ukubera ko ubuhanga bwo gukora imibonano mpuzabitsina ari bubi, ahubwo ni ukubera ko abareba amakuru bakwiye kumenya niba amakuru yasubiwemo cyangwa yafashwe. Ibyo ni ... kubaha gusa.

Komeza imiterere y'ikintu, aho ikirango giherereye, ibimenyetso bya lens, impande z'utubuto, n'imiterere y'ubuso byegeranye n'umwimerere uko bishoboka kose. Koresha uburyo bwo gusukura buhoro, gukamura buhoro, kandi wirinde guhanga inyandiko z'inyongera, gushwanyaguza, ibirango, imibare y'uruhererekane, cyangwa ibisobanuro birambuye by'imitako. Ishusho ya nyuma igomba kugaragara nk'isanzwe ku bunini busanzwe bw'ipaji y'ibicuruzwa, ntabwo igomba kuba ikoze mu buryo bw'ubukorano kuri zoom ya 400%.

Uburyo bwo kubigerageza

Tangira ukoresheje amashusho atanu avanze mbere yo gutunganya itsinda ryose:

Ifoto imwe isukuye y'igicuruzwa ifite urumuri rwiza

Ishusho imwe yashyizwemo JPEG ifite ubushobozi bwo kuziba

Ifoto imwe ifite utumenyetso duto twanditseho cyangwa utumenyetso tw'indorerwamo

Ishusho imwe yijimye irimo urusaku mu gicucu

Ishusho imwe irimo icyuma cyangwa ikirahure bigarura urumuri

Nyuma yo kongera ingano, gereranya buri gisubizo ugereranije n'icya mbere kuri 100% na 200%. Reba niba amazina y'ibirango, utudomo, vis, ports, n'imiterere y'imiterere bigihuye. Niba moderi ikora "inyuguti hafi ya zose" cyangwa ibimenyetso by'ubuso bw'impimbano, gabanya uburyo bwo gutyaza cyangwa kugarura amakuru mu buryo burambuye.

Ibisubizo

Ibisubizo by'icyitegererezo: bishingiye ku gihe cy'igerageza ry'amashusho atanu mbere na nyuma yo gukoresha iyi gahunda y'ibikorwa.

Gusukura no guhindura ingano byatwaye iminota 9 kuri buri shusho, cyangwa iminota 45 ku mashusho atanu.

Uburyo bwo gukora amashusho bwakoreshejwe na AI bwatwaye iminota 3 kuri buri shusho, cyangwa iminota 15 ku mashusho atanu.

Ni ukuvuga ko iminota 30 yazigamwe ku mashusho atanu, cyangwa amasaha agera kuri 4 yazigamwe mu mashusho 40.

Ibisubizo byo kugenzura ubuziranenge: Amashusho 4 kuri 5 yatsinze isuzuma rya mbere. Ishusho imwe yananiwe kubera ko ifoto yazamuwe yahinduye inyandiko ntoya, bityo yongera gutunganywa hakoreshejwe uburyo bwo gukosora no kudakosora inyandiko.

Igipimo cy'agaciro hano si "gusa neza gusa". Ni: ni amashusho angahe anyura mu isuzuma ry'impande nta makuru arambuye yahimbwe?

Ni iki gishobora kugenda nabi

Icyitegererezo gishobora guhindura ivumbi, uduce twa JPEG, cyangwa uduce duto tw’ibishushanyo mbonera tukahinduka "imiterere nyayo".

Inyandiko ntoya ishobora guhinduka inyandiko mpimbano isa n'aho yizewe kugeza igihe ugeze kuri zoom.

Gukarisha cyane bishobora gutuma impande z'ibicuruzwa zizunguruka.

Gutunganya ibintu mu buryo butandukanye bishobora guhisha amakosa, bityo rero banza usuzume icyitegererezo mbere yo kohereza byose hanze.

Ku bucuruzi bwo kuri interineti, itegeko ryizewe ni iryoroshye: ntuzigere ukoresha AI yongereye ubwiza kugira ngo uhishe ibyangiritse, uhindure imiterere, cyangwa ngo utume ibicuruzwa bisa bishya kurusha uko biri.

Gufata ibintu mu buryo bufatika

Gutunganya ubuhanga bwa AI bikora neza iyo ubifashe nk'intambwe yo kurangiza igenzurwa, atari buto yo gusana idasanzwe. Koresha igenamiterere rya 2× rihoraho, reba amakuru abaguzi bitaho, kandi ukomeze ishusho y'umwimerere kugira ngo verisiyo yahinduwe ikomeze kuba nziza.

Urugero rw'ukuri: Guhindura imiterere ya videwo ishaje y'imyitozo nta kuyihindura irabagirana

Imiterere y'ibyabaye

Isosiyete ntoya y’amahugurwa ifite videwo y’iminota 7 yerekana umutekano yafashwe mu 2014 kuri 720p. Ibikubiye muri iyo videwo biracyafite agaciro, ariko amashusho asa n’aho ari meza ku rubuga rushya rw’iyi sosiyete, cyane cyane kuri ecran nini za mudasobwa zigendanwa.

Itsinda rirashaka kohereza verisiyo ya 1080p isukuye idasubiwemo. Ingaruka ni uko kongera ubushobozi bwa AI mu buryo bukomeye bishobora gutuma amasura asa n'aho asa n'aho ari ibirungo, guhindura ibyapa ku nyandiko "hafi amagambo", cyangwa gukora imiterere ihindagurika kuva ku ishusho imwe kugera ku yindi.

Intego si ugutuma videwo isa n'iyishya. Ahubwo ni ukuyigaragaza neza, ihamye kandi idakomeye, ariko kandi igakomeza kugaragara neza mu gihe isura y'umwarimu, ibyapa byo kumuburira, imigendekere y'intoki, n'ibisobanuro by'ibikoresho bihuye n'ibya mbere.

Icyo gahunda y'akazi ikeneye

Dosiye y'umwimerere ya videwo, ntabwo ari ugukurura ku mbuga nkoranyambaga byakaswe niba bishoboka

Ingano y'ibyoherezwa mu mahanga, nka 720p kugeza 1080p aho kwihutira kugera kuri 4K

Videwo igezweho ifite uburyo bwo gukurura urusaku, gutyaza, gusana gukanda, no guhuza ibintu mu gihe runaka

Akadomo gato k'igerageza karimo amasura, ingendo, inyandiko, n'ubuso burambuye

Urutonde rw'isuzuma ry'impinduka, imitumba, inyandiko igoramye, imiterere y'isura, n'impande zigenda

Kopi yabitswe ya videwo y'umwimerere kugira ngo uyigereranye kandi uyishyire ahagaragara nibiba ngombwa

Amabwiriza y'urugero

Koresha ubu bwoko bw'amabwiriza mbere yo gutunganya videwo yose:

Hindura iyi videwo y'imyitozo ya 720p uyishyire kuri 1080p. Shyira imbere ingendo karemano, impande zihamye, inyandiko isanzwe isomwa, n'imiterere y'uruhu ifatika. Koresha uburyo bwo gusana uruhu rworoshye kandi ukarishye gake. Ntugahimbe inyandiko ibura, ibirango, ibirango, iminkanyari, ibimenyetso byo mu maso, cyangwa ibimenyetso by'ibikoresho. Irinde ko ishusho igaragara kuva kuri frame kugeza kuri frame. Ibisubizo bya nyuma bigomba kugaragara neza ukurikije ingano isanzwe yo kureba, atari ubukorikori bukabije iyo uhagaritse akazi kandi ukoresheje zoom.

Uburyo bwo kubigerageza

Mbere yo gutunganya dosiye yose y'iminota 7, ohereza icyitegererezo cy'amasegonda 20 kirimo:

Isura y'umwarimu ubwo yavugaga

Ukuboko kugenda hejuru y'umukingo

Ikimenyetso cy'umuburo cyangwa inyandiko ntoya yacapwe

Ubuso bufite imiterere, nk'imyenda, sima, icyuma gikozwe mu buryo bwa brushed, cyangwa pulasitiki

Isafuriya ya kamera cyangwa ikindi kintu cyose kinyeganyega

Reba icyitegererezo kabiri: rimwe ku muvuduko usanzwe hanyuma rimwe ugahagarika icyitegererezo ku kindi. Ku muvuduko usanzwe, shakisha uko ibintu bigenda bihindagurika, imiterere ihindagurika, cyangwa uko bigenda bidasanzwe ku nkengero. Iyo uhagaritse, gereranya verisiyo z'umwimerere n'izagezweho kugira ngo urebe niba inyandiko, utubuto, ibikoresho, n'imiterere y'isura bigihuye.

Ibisubizo

Ibisubizo by'icyitegererezo: bishingiye ku gupima igihe cy'amasegonda 20 hanyuma ugakoresha igenamiterere rimwe kuri videwo y'iminota 7.

Uburyo bwo gukora akazi ko "guhindura ingano no kunoza" bwakoreshejwe n'intoki bwatwaye iminota 35, harimo no kohereza no gusuzuma, ariko ibisubizo byagaragaje ko umusatsi w'umwarimu ugaragara neza ndetse n'impande zombi zikikije ibimenyetso by'umutekano.

Imikorere yakoreshejwe na AI yatwaye iminota 55 harimo no kugerageza kohereza ibicuruzwa mu mahanga, ariko yagabanyije ibibazo byo gusuzuma biva ku bibazo 8 byagaragaye mu kohereza ibicuruzwa mu mahanga bwa mbere bijya ku bibazo 2 bito mu kohereza ibicuruzwa mu mahanga bwa nyuma.

Verisiyo ya nyuma yatsinze igenzura 10 kuri 12 ryari ku rutonde rw'isuzuma. Ibibazo bibiri bisigaye byari ubworoherane gato ku nyandiko y'inyuma n'urusaku ruto mu mfuruka imwe yijimye. Byombi byemewe kubera ko umwarimu, ibikoresho, n'intambwe z'umutekano byagumye bihuye neza n'amaso.

Igipimo cy'ingenzi hano si "1080p yagezweho". Ni: ni amasegonda angahe y'ikiganiro cya videwo kirangaza ibintu mu gihe cyo gukina bisanzwe?

Ni iki gishobora kugenda nabi

Iyi moderi ishobora gukarisha uduce duto two gukandagiramo ibintu bigatuma bisa n'imiterere nyayo.

Inyandiko nziza ishobora kugaragara nk'aho ifite icyizere ariko ntibe nziza.

Mu maso hashobora kuba heza cyane iyo urusaku rukabije.

Impande zigenda zishobora kumera neza iyo igikoresho gifashe buri gitereko mu buryo bwihariye.

Kohereza amashusho ya 4K bishobora kugaragara nabi kurusha kohereza amashusho ya 1080p mu buryo bugenzurwa kuko moderi igomba guhanga ibintu byinshi cyane.

Ikosa rikomeye ni ugusuzuma gusa ishusho yahagaze. Kuzamura amashusho bigomba kugaragara nk'ibisanzwe mu buryo busanzwe, atari ishusho itangaje gusa.

Gufata ibintu mu buryo bufatika

Ku bijyanye na videwo, kongera ubushobozi bwo gukora amashusho ya AI bikora neza iyo ugerageje igice gito mbere, ugakoresha uburyo bworoshye, kandi ugasuzuma uko ibintu bigenda mbere yo kubigaragaza neza. Ibisubizo byoroshye ariko bihamye akenshi biba byiza kuruta verisiyo isobanutse neza ihita ihinduka buri gihe iyo umuntu yimutse.

Ibibazo Bikunze Kubazwa

Kongera ubushobozi bwa AI n'uko ikora

Kuzamura imiterere y’ubuhanga mu bya siyansi (akenshi byitwa "super-resolution") byongera ubushobozi bw’ishusho binyuze mu guhanura ibisobanuro birambuye by’imiterere y’ubuhanga mu byakoreshejwe mu gihe cy’imyitozo. Aho kugira ngo habeho gusa pixels nka bicubic interpolation, moderi yiga impande, imiterere, amasura, n’imirongo isa n’inyandiko, hanyuma igatanga amakuru mashya ya pixels ahuye n’ayo mashusho yize. Ni "kugarura ukuri" cyane ahubwo ni "gutekereza ibintu bifatika" nk'ibisanzwe.

Kongera ingano ya AI ugereranije na bicubic cyangwa ihinduka rya gakondo

Uburyo gakondo bwo kongera uburebure (nk'ibicubic) ahanini buhuza hagati ya pikseli zisanzweho, bukoroshya impinduka zidakozwe mu buryo bushya. Gushyira uburebure bwa AI bigamije kongera imiterere ishoboka binyuze mu kumenya ibimenyetso bigaragara no guhanura uko verisiyo z'ibyo bimenyetso zigaragara cyane. Niyo mpamvu ibisubizo bya AI bishobora kumvikana neza cyane, ndetse n'impamvu bishobora kwinjiza ibintu bishya cyangwa "guhimba" ibisobanuro bitari mu isoko.

Impamvu amasura ashobora kugaragara nk'ibisigazwa cyangwa agasa neza cyane

Ubusanzwe amasura afite ibisigazwa biva mu gukurura urusaku no koroshya uruhu, bijyana no gukarisha imiterere yarwo isanzwe. Ibikoresho byinshi bivura urusaku n'imiterere myiza y'uruhu kimwe, bityo "gusukura" ishusho bishobora gusiba imyenge n'utundi duce duto. Uburyo busanzwe ni ukugabanya gukarisha no gukarisha, gukoresha uburyo bwo kubungabunga isura niba buhari, hanyuma ukongera gushyiramo akantu gato kugira ngo umusaruro ugaragare nk'uwa plastiki nkeya kandi ugaragare neza.

Ibikoresho bisanzwe byo kongera ubushobozi bwa AI byo kwitondera

Ibimenyetso bisanzwe birimo ibirahuri bikikije impande, imiterere isubirwamo (nk'amatafari yo gukoporora no gupakira), itandukaniro rito ry'inyuguti, n'inyandiko ihinduka "inyuguti hafi ya zose." Mu mikorere ishingiye ku gukwirakwiza, ushobora kandi kubona uburyo bwo gukurura amakuru aho ibintu bito bihinduka mu buryo butunguranye. Kuri videwo, uburyo bwo gukurura no gukurura amakuru ku mashusho ni ibimenyetso binini bitukura. Niba bisa neza gusa kuri zoom ikabije, imiterere ishobora kuba ikomeye cyane.

Uburyo GAN, CNN, n'abashinzwe iterambere ry'ikwirakwizwa ry'amakuru bakunda gutandukana mu musaruro

Uburyo bwa super-resolution bushingiye kuri CNN bukunze kuba buhamye kandi bushobora kwiteganwa, ariko bushobora kugaragara nk "bwatunganyijwe" iyo busunitswe cyane. Amahitamo ashingiye kuri GAN (ESRGAN-style) akunze gutanga imiterere itangaje n'ubuhanga bugaragara, ariko ashobora gutuma ibintu bitagenda neza, cyane cyane ku maso. Kuzamura imiterere bishingiye ku gukwirakwiza bishobora gutanga ibintu byiza kandi bishoboka, ariko bishobora kuva ku miterere y'umwimerere niba ubuyobozi cyangwa imbaraga bikomeye cyane.

Ingamba zifatika zo kwirinda isura "y'ubuhanga bwo gukora imibonano mpuzabitsina"

Tangira gukoresha uburyo bwo kuboneza urubyaro: 2× cyangwa 4× mbere yo kugera ku bintu bikomeye. Niba amasura asa n'ay'iplastike, shyira inyuma urusaku rworoshye hanyuma ukarishe hanyuma ugerageze uburyo bwo kumenya isura. Niba imiterere ibaye myinshi cyane, gabanya uburyo bwo kongeramo ibice hanyuma utekereze kongeramo uduce duto nyuma. Niba impande ziraka, gabanya uburyo bwo gukarishya hanyuma urebe ko hagaragara neza cyangwa hadakoreshejwe ibikoresho. Mu miyoboro myinshi, "hafi" intsinzi kuko irinda ukuri kw'ibintu.

Gufata amashusho ya scan ashaje cyangwa amashusho yashyizwemo JPEG nyinshi mbere yo kongera ubwiza

Amashusho apfunyitse aragoye kuko moderi zishobora gufata ibikoresho bya block nk'imiterere nyayo no kubikuza. Uburyo busanzwe bwo gukora ni ukubanza gukuraho cyangwa gukuraho ibikoresho bya artifact, hanyuma kongera uburebure, hanyuma gukarisha urumuri gusa iyo bikenewe. Ku bijyanye na scan, gusukura buhoro buhoro bishobora gufasha moderi kwibanda ku miterere nyayo aho kwibanda ku kwangirika. Intego ni ukugabanya "ibimenyetso by'imiterere y'impimbano" kugira ngo umuntu uzamuka adahatirwa gukekeranya yizeye bivuye ku bintu byumvikana.

Impamvu kongera ubwiza bwa videwo bigoye kurusha kongera ubwiza bwa videwo

Kuzamura amashusho bigomba kuba bihuye ku mashusho yose, atari byiza gusa ku ishusho imwe idahinduka. Iyo ibisobanuro bihindagurika biva ku mashusho bijya ku mashusho, ibisubizo bihita bihindagurika. Uburyo bwo kwibanda kuri videwo bukoresha amakuru y'igihe aturuka ku mashusho yegeranye kugira ngo bukomeze gusanwa no kwirinda ibintu bibengerana. Imikorere myinshi irimo kandi gukuramo urusaku, gukuramo inyuguti ku masoko amwe, no kongera gukoresha ibinyampeke ku buryo urukurikirane rwose ruhurirana aho kuba rutyaye.

Iyo kongera ikoranabuhanga rya AI bidakwiye cyangwa ari ibintu bishobora guteza akaga kwishingikirizaho

Kuzamura ubuhanga mu gukora isuzuma ry’ubukorano (AI) ni byiza ko bifatwa nk'inyongera, si ikimenyetso. Mu bihe bikomeye nko mu itangazamakuru, ibimenyetso by’amategeko, amashusho y’ubuvuzi, cyangwa imirimo yo mu rwego rw’ubugenzacyaha, gukora pixel "zizewe" bishobora kuyobya kuko bishobora kongeramo amakuru atari yafashwe. Uburyo bwiza bwo gukoresha filime ni ukuyikoresha mu buryo bw'ikigereranyo no kugaragaza ko inzira ya AI yongeye kubaka amakuru. Niba ukuri ari ingenzi, komeza inyandiko z’umwimerere kandi wandike buri ntambwe n’imiterere y’isesengura.
