Ukufunda ngoomatshini kunjalo omnye umkhwa esizifumana sikuyo ngalo mzuzu kwaye sithetha ukuba sinokuthatha ithuba lokufumana iingcebiso ezingcono xa simamela olu ludwe lomculo kuDlalo lukaGoogle loMculo. Ngezolo nje besihlomla ngomdlalo kaG omkhulu ngohlaziyo olutsha kunye nokufunda koomatshini okuya kufunda ngakumbi ngawe njengoko usebenzisa usetyenziso ngakumbi.
Ngoku ufuna ukusebenzisa loo njini kuzo zonke ezo foto zithintelwe sisisombululo sesixhobo okanye yinkumbulo encinci yangaphakathi yesixhobo. UGoogle akafuni kuphoswa lithuba lokuba iifoto zesisombululo esiphezulu zifuneka ngakumbi, kuba izikrini, ezinjengezo zeTV ezihlakaniphile okanye iiphablets, ziyabafuna. Yiyo loo nto iye yenza njalo yazisa ubuchule obubizwa ngokuba yi-RAIR.
"I-RAIR: Umfanekiso oKhawulezayo kwaye ochanekileyo oSosombululo ophezulu"
Bubuchule obubandakanya ukufunda koomatshini velisa iinguqulelo ezikumgangatho ophezulu wemifanekiso enesisombululo esisezantsi. I-RAISR ivelisa iziphumo ezithelekiseka okanye ezingcono kuneendlela ezifumanekayo ze-super-resolution, kwaye ide iphucule ixesha lokugqitywa nge-10 ukuya kwi-100 amaxesha. Esi santya kwinkqubo sivumela ukuba zifumaneke kwisixhobo ngexesha langempela. Nasemva kwexesha, obu buchule buya kukuvumela ukuba uthintele ukuphinda uvelise i-aliasing okanye i-artifact ejijekileyo ekhoyo kwimifanekiso enesombululo esisezantsi.
Kwiminyaka ethile kukho a ubuchule obubizwa ngokuba yi-Upsampling, evelisa umfanekiso omkhulu kunye nenani eliphezulu leepikseli kunye nomgangatho womfanekiso ophezulu ukusuka kwisisombululo esisezantsi. Ubuchule obusebenzisa iindlela zomgca ezigcwalisa amaxabiso epixel entsha ngokusebenzisa indibaniselwano yamaxabiso ayingqongileyo. Le ndlela iyakhawuleza kuba zizihluzo ezilayini. Nangona yintoni eyenza ukuba zikhawuleze, azisebenzi kangako ekuboniseni iinkcukacha ezicacileyo kwiziphumo zesisombululo esiphezulu. Umfanekiso ongezantsi ubonisa ngokugqibeleleyo.
Isebenza njani iRAIR
I-RAIR isebenzisa i ukufunda koomatshini ngemifanekiso emibini, enye yomgangatho ophantsi kunye nenye ephezulu, ukufumana izihluzi ezithi, xa zikhethwa ngokukhethiweyo kwipikseli nganye yomfanekiso wesisombululo esisezantsi, ziyakuphinda zenziwe iinkcukacha ezithelekiseka nomgangatho woqobo. I-RAISR "inokuqeqeshwa ngeendlela ezimbini." Eyokuqala yindlela ethe ngqo, apho izihluzi zifundwa ngokuthe ngqo kwiibini zemifanekiso ephantsi kunye nesisombululo esiphezulu. Enye indlela igqithisa icebo lokucoca elifana nelo upsampler kumfanekiso wesisombululo esisezantsi kwaye emva koko "ufunde" izihluzo ukusuka kupasi elinikiweyo kunye nomfanekiso wesisombululo esiphezulu.
Nokuba yeyiphi na indlela, izihluzi ze-RAISR "Baqeqeshiwe" ngokweempawu "zeencopho" ezifumaneka kwiipatches zemifanekiso emincinci, efana nombala / ukugqama kwegradients, i-textured okanye imimandla ethe tyaba kunye nokunye, okubonakaliswa ngumkhombandlela, amandla kunye nokuhambelana.
Ngamafutshane, ngexesha lokwenyani iRAISR ikhetha kwaye isebenzise ezona zihluzo zifanelekileyo kuluhlu lwezo zifundiweyo kwipixel nganye engummelwane kumfanekiso okwisisombululo esisezantsi. Xa ezo zihluzo zisetyenziswa kowona mfanekiso usemgangathweni ombi, yenza kwakhona iinkcukacha ezithelekiseka ngokomgangatho neyokuqala isisombululo esiphezulu. Into eyenzayo le kukuphelisa izinto zakudala ezijijekileyo ezifana neepateni zikaMoire nokunye.
Namhlanje, ukusetyenziswa komatshini wokufunda, kwi-tandem yamashumi eminyaka yenkqubela phambili kwitekhnoloji ye-imaging, ivumele inkqubela phambili ekuqhubeni umfanekiso oneenzuzo ezininzi ezahlukeneyo. Omnye wemizekelo enikwe nguGoogle iya kuba kukuphucula "pinch to zoom" okanye "pinch" gesture kwifowuni, okuthetha ukuba inokubanjwa, igcinwe okanye ukuthumela imifanekiso kwisisombululo esisezantsi ukuze ekugqibeleni ifikelele kwindawo yayo ngesisombululo sayo esifanelekileyo kunye nomgangatho ophezulu. Oku kuya kuthetha ukonga okukhulu kwidatha esetyenziswa kudluliselo nogcino izicwangciso.
