Indlela yokulungisa ukukhanya okungahambelaniyo kwimixholo eyenziwe nge-AI

Izithunzi ezingahambelaniyo zibangelwa kukuba uninzi lweemodeli zomfanekiso lisebenza ngeepikseli ngokuzimeleya okanye ngamaqhekeza amancinci, nto leyo ebangela ukuba zibale iikona zokukhanya ngokwahlukeneyo kwiintlobo ezahlukeneyo zezinto endaweni yokulinganisa indawo ebonakalayo eyodwa. Uyilungisa le nto ngokuchaza ngokucacileyo umthombo omnye wokukhanya okunobuchule kwi-prompt yakho, usebenzise amagama obuchule anyanzela imodeli ukuba ihambelane nezithunzi kwi-aksisi ethile.

Chonga Ingxaki: Imithombo emininzi yokukhanya nezithunzi ezingenakubona ubunzulu

Phambi kokuba ulungise i-prompt yakho, kufuneka uqaphele iimpawu zokubona zokukhanya okungahambelaniyo. Jonga imiphetho yezinto. Ingaba izithunzi ziwa kwicala elichaseneyo? Ingaba into enye ikhanyiswe ngasekhohlo ngelixa ummelwane wayo ukhanyiswe ngasekunene? Le yeyona mpawu iphambili yempazamo yemithombo emininzi. Enye impawu eqhelekileyo kukungabikho kobunzulu. Ukuba into ibonakala njenge-sticker phezu komva, ingenazo iinkcukacha zobunzulu ezivela kusebenzisana kwezithunzi, imodeli ayiphumelelanga ukudibanisa isihloko kwilogic yokukhanya yomxholo.

Izithunzi ezingenakubona ubunzulu zihlala zibangelwa ziisetingi zokukhanya okuphezulu okanye ii-prompts ezingacaciswanga njenge "bright and airy." La magama anceda imodeli ukuba isasaze ukukhanya ngokulinganayo, isuse iinkcukacha zokukhanya okunobuchule ezifunekayo ukuqonda ubunzulu. Ukuyixelela le nto, yima kumfanekiso ulandele umphetho wesithunzi sesihloko esiphakathi. Emva koko, landela umphetho wesithunzi sesiqalelo somva. Ukuba la magama awahambelani, ukukhanya kwakho akuhambelani. Oku kungahambelani kokubona kudala uzivo ongaphantsi kokungayinyani, wenze umfanekiso uzive ungcolile okanye wenziwe ngedijithali kunokuba uthathwe ngomfanekiso. Ukuqaphela le pateni kukunceda ukuba ubeke phambili imiyalelo ethile yokukhanya okunobuchule kunamagama jikelele obuhle.

Chaza umthombo ophambili wokukhanya kwi-Prompt

Indlela ephumelelayo yokudibanisa umxholo wakho kukubhengeza umthombo omnye, ophambili wokukhanya. Gwema amagama jikelele njenge "well-lit" okanye "good lighting," anganiki ngcaciso yejometri. Endaweni yoko, chaza indawo kunye nemo yokukhanya. Cinga nge-prompt yakho njengediagram yokukhanya. Ikuphi ilanga? Ikuphi ilambu?

Sebenzisa ulwimi oluchanekileyo lokumisa. Umzekelo, "ukukhanya kwelanga okusuka kwicala lasekhohlo eliphezulu" kumisela i-vector ecacileyo. Imodeli ibe isibala izithunzi ukuze ziwele kwicala lasekunene elisezantsi kuzo zonke izinto kwifreyimu. Oku kungqinelana kudala ubumbano. Ukuba usebenza ngeendawo zangaphakathi, chaza "ukukhanya okufudumeleyo kwangaphakathi kusuka kwifestile engasekhohlo ngaphambili." Oku kubhala imodeli ukuba ithathe ifestile njengomthombo omnye kuphela, ukuqinisekisa ukuba izithunzi phantsi nasodongeni zihambelana nokukhanya okungena kwelo cala lichanekileyo.

Qwalasela ukukhanya kunye nobushushu bommbala ngokunjalo. "Ukukhanya okupholileyo kwifestile ejonge emantla" kuvelisa iimpawu zezithunzi ezahlukileyo kune "ukukhanya okufudumeleyo kwelanga elishonayo." Ngokuchaza uphawu lomthombo, unceda imodeli ukuba igcine ukuboniswa kombala okungqinelanayo kuyo yonke indawo ekujongwe kuyo. Izinto eziphambili nezingasemva kufuneka zabelane ngombala ofanayo ukuba zikhanyiswe ngumthombo omnye. Ukuba into ephambili iphaphathekile kwaye engasemva iluhlaza okwesibhakabhaka, imodeli iziphatha njengemeko yokukhanya eyahlukileyo. Bamba i-prompt yakho kumthombo omnye ochanekileyo ukuthintela olu hlukano.

Sebenzisa Amagama Okukhanya Anobuchule

Isigama esikhethekileyo sisebenza njengendlela emfutshane yokumisa ukukhanya okuntsonkothileyo. Endaweni yokuchaza impembelelo, chaza icala. Nanga amagama aphambili aqinisekisa ukungqinelana:

• Backlit: Umthombo wokukhanya usemgqabeni wento ekhanyisiweyo. Izithunzi ziwa ngakumhlobo. Oku kudala ukukhanya komphetho kwaye kwahlula into ekhanyisiweyo kumva. Qinisekisa ukuba uchaza ukuba umva kufuneka ube mnyama okanye ukhanye, njengoko iindawo ezikhanyiswe ngasemva zinokulahlekelwa ziinkcukacha kwizithunzi.
• Side-lit: Ukukhanya kuvela kwicala lasekhohlo okanye lasekunene. Oku kubalaselisa imvelaphi kunye nemilo. Izithunzi ziwa ngokuthe tye ebusweni okanye kwinto. Oku kulungile kwiiphothilethi okanye imifanekiso yemveliso apho kufuneka ubunzulu. Chaza "ukukhanya okusecaleni kwasekhohlo" ukuqinisekisa ukuba zonke izithunzi zijonge ekunene.
• Overhead: Ukukhanya kuvela ngqo phezulu. Izithunzi ziwa ngqo ezantsi, rhoqo phantsi kwentshebe okanye phantsi kwezinto. Oku kudala umahluko ocacileyo kwaye kuluncedo kwiminyaka yemini okanye iindawo ezinemvelaphi. Yiba nokhathalelo ngamagama "emini yasekhohlo", anokudala izithunzi ezinzima ezingakhanyisiyo ebusweni. Dibanisa "phezulu" no "ukukhanya okuthambileyo okusasaziweyo" ukuba ufuna ukunciphisa ubungqongqo ngelixa ugcina ukuhambelana kokukhanya okunobuchule.
• Rim-lit: Ifana ne-backlit kodwa igxile kumiphetho. Sebenzisa oku xa ufuna into ekhanyisiweyo ivele kumva omnyama. Qinisekisa ukuba icala lokukhanya komphetho lihambelana necala lokukhanya okuphambili ukuze uphephe ukukhanya okungahambelaniyo.

Ukudibanisa ezi magama nendawo kwenza umyalelo oqinileyo. "Ukukhanya okusecaleni kwasekhohlo nezithunzi ezithambileyo" icacile kunokuthi "ukukhanya okusecaleni" nje. Igama elithi "ethambileyo" litshintsha umgangatho womphezulu wesithunzi, ngelixa "ekhohlo" ilungisa i-engile. Oku kuchaneka kunciphisa amathuba okuba imodeli yenze iingxelo zezithunzi ezingaqhelekanga kwiindawo zangasemva.

Lungisa iisetingi zomahluko nokukhanya ukuze kube nokuhambelana

Ukungaguquguquki kokukhanya akumalunga nje ngobuchule; kuphathelene nokuncipha kwamandla okukhanya. Kwiindawo zebhayoloji, amandla okukhanya ayancipha ngokomgama. Ekwenziweni kwe-AI, kufuneka ulingise oku kuncipha kwendalo ngokusebenzisa izikhokelo zomahluko nokukhanya. Ukuba indawo yakho inobunzulu, umva kufuneka ube nomahluko omncinci okanye ube mnyama kancinci kunento ephambili engaphambili, ukuba umthombo wokukhanya ukufuphi nento ephambili.

Sebenzisa amagama anjengo "high contrast" ukuqinisa umahluko phakathi kweendawo ezikhanyayo nezithunzi. Oku kunyanzela imodeli ukuba yenze izithunzi ezicacileyo ngakumbi, nto leyo eyenza iimpazamo zolungelelwaniso zibonakale ngakumbi kodwa zibe lula ukuzilungisa. Ngokuchaseneyo, "low contrast" okanye "flat lighting" inokufihla ukungahambelani kodwa ihlala ivelisa imifanekiso engacacanga. Jolise kumahluko olinganayo obonisa icala lokukhanya.

Useto lokukhanya kwi-prompt yakho luchaphazela inani leenkcukacha ezihlala kwiindawo ezimnyama. "Ukukhanya kweendawo ezimnyama" kuqinisekisa ukuba iindawo ezimnyama zigcina ithakstha nemibala, okukunceda ukuqinisekisa ukuba iikona zeendawo ezimnyama ziyahambelana. Ukuba iindawo ezimnyama zityumekela emnyama, awukwazi ukugweba ulwalathiso lwazo. Ngoko ke, cela ukukhanya okwaneleyo kwiindawo ezimnyama. Umzekelo, "iindawo ezimnyama ezikhanyiswe kakuhle ezibonisa ubunzulu" zikhuthaza imodeli ukuba ibonise iinkcukacha zeendawo ezimnyama endaweni yokuzivala. Oku kuvumela ukuba uqinisekise ngokubona ukuba i-vector yendawo emnyama iyahambelana kwisithombe sonke.

Ukujonga Emva Kokuveliswa Kokuhambelana Kweendawo Ezimnyama

Xa isithombe sivelisiwe, yenza ukujonga okukhawulezayo kwejometri. Ungaxhomekeki kuphela kwimpembelelo yonke ye-aesthetic. Yandisa kwindawo apho isihloko sidibana khona nomphezulu esihlala kuwo. Ingaba indawo emnyama ilandela umda womphezulu? Ingaba ibhekisa kwicala elinye njengendawo emnyama yento ekufutshane?

Ukuba ubona ukungahambelani, ungaphindi uvelise kwakhona ngokukhawuleza. Okokuqala, hlaziya i-prompt yakho ngeengcebiso ezicacileyo zolwalathiso. Yongeza amabinzana afana "ulwalathiso oluhambelanayo lwendawo emnyama" okanye "imeko yokukhanya eyomanyano." Ngamanye amaxesha, ukongeza isalathiso kwixesha elithile lomhla kunceda. "Ilanga lamva kutshona" lithetha ikona ephantsi, eyenza iindawo ezimnyama ezinde, ezihambelanayo. Lo mngcipheko wendalo unceda imodeli ihambelane neendawo ezimnyama ngokulogical ngakumbi kunye nemiyalelo engaqondakaliyo.

Ukuba ukungahambelani kuqhubeka, qwalasela ukubeka amaleko. Yvelisa umva kunye nesihloko ngokwahlukeneyo ngee-prompts zokukhanya ezihambelanayo, emva koko uzidibanise kwisoftware yokuhlela. Oku kukunika ulawulo lwesandla kwi-hambelano yeendawo ezimnyama. Nangona kunjalo, kwiimeko ezininzi, ukuhlaziya i-prompt yokuqala ngolwimi oluchanekileyo lolwalathiso kukhawuleza kwaye kunika ukudityaniswa okwendalo ngakumbi. Khumbula, injongo yingqiqo enye yokukhanya. Yonke into kwisakhelo kufuneka ithobele imithetho efanayo ye-physics ebekwe ngumthombo wakho ophambili wokukhanya.
