Key Takeaways
- Kev nce qib tshiab los nthuav cov duab tuaj yeem pab nrog txhua yam ntawm tsev neeg cov duab mus rau kev kho mob.
- Google cov kws tshawb fawb tau tshaj tawm tias lawv tau ua tiav kev siv AI txhawm rau txhim kho cov duab daws teeb meem.
- Tab sis ib tus kws tshaj lij hais tias kev txhim kho software yuav tsis tsim nyog rau cov kws yees duab.
Cov tswv yim tshiab uas nthuav cov duab siv AI tuaj yeem txhim kho txhua yam ntawm cov duab mus rau video game graphics, cov kws tshaj lij hais.
Google cov kws tshawb fawb tsis ntev los no tau sib tham txog kev ua tiav lawv tau ua hauv kev txhim kho cov duab. Cov kws tshawb fawb tau siv cov qauv kev kawm tshuab los hloov cov duab qis rau hauv cov duab ntxaws ntxaws. Nws yog ib feem ntawm txoj kev loj hlob ntawm kev siv AI los txhim kho cov duab.
"Peb tab tom pom kev nce qib hauv AI-powered upscaling, tshwj xeeb tshaj yog hauv kev ua si, qhov chaw thev naus laus zis zoo li NVIDIA DLSS siv tshuab kev kawm los tsim cov duab daws teeb meem ntau dua, uas sib tw, thiab qee zaum tshaj qhov zoo ntawm cov duab ib txwm muaj., " tus kws tshaj lij duab Ionut-Alexandru Popa hais rau Lifewire hauv kev xam phaj email.
"Qhov kev nce qib no ua haujlwm zoo hauv kev ua si hauv computer, qhov uas nws tswj tau siv cov peev txheej tsawg dua li ua ncaj qha rau cov duab zoo dua."
Tsim Pixel
Google tau tshawb nrhiav ib txoj hauv kev los txhim kho cov duab uas siv tus qauv hu ua diffusion qauv.
Lub tuam txhab thov tias cov txheej txheem no txhim kho cov thev naus laus zis uas twb muaj lawm thaum tib neeg raug thov los txiav txim cov txiaj ntsig. Ib txoj hauv kev uas Google siv yog hu ua SR3, lossis Super-Resolution ntawm Kev Rov Ua Dua Tshiab.
"SR3 yog tus qauv kev daws teeb meem zoo tshaj plaws uas yuav siv sij hawm raws li cov duab daws teeb meem qis thiab tsim kom muaj cov duab zoo sib xws los ntawm lub suab nrov," Google cov kws tshawb fawb tau sau rau hauv blog ncej."Tus qauv tau kawm txog cov txheej txheem kev noj nyiaj txiag hauv cov duab uas muaj suab nrov ntxiv mus rau cov duab siab kom txog thaum tsuas yog cov suab nrov xwb."
Upscaling cov tswv yim tsis yog tshiab thiab feem ntau siv hauv daim ntawv thov kho duab, Popa hais.
"Muaj ntau qhov xwm txheej thaum koj xav tau cov duab daws teeb meem siab dua, yog li kev nce qib yog siv los tsim pixels ntawm cov uas twb muaj lawm," nws hais ntxiv. "Feem ntau cov neeg tsis paub, tab sis thaum lawv saib TV ntawm lawv lub vijtsam 4K, 1080p video teeb liab tau nce siab los npog tag nrho lub vijtsam. Qhov no yog ua tiav los ntawm koj lub TV teeb."
Ntau cov tswv yim tam sim no tau siv los 'xav' cov ntsiab lus ntawm cov pixels tshiab kom cov duab tshwm sim zoo, Popa hais.
"Tam sim no, feem ntau siv algorithms rau cov duab upscaling yog bilinear thiab bicubic txoj kev, uas ua kom muaj kev hloov pauv tsis tu ncua ntawm cov pixels uas nyob ib sab, nrog maj mam hloov xim, tab sis txoj kev no feem ntau ua rau poob ntawm sharpness," nws hais ntxiv."Qhov no tau them nyiaj ib nrab los ntawm kev siv cov hlais hla dhau ntawm daim duab nce ntxiv."
Muaj ntau qhov xwm txheej thaum koj xav tau cov duab daws teeb meem siab dua, yog li kev nce qib yog siv los tsim pixels ntawm cov uas twb muaj lawm.
Kev nce duab yog qhov tseem ceeb rau kev lom zem, xov xwm, thiab internet ua haujlwm li cas, tus kws yees duab Sebastien Coell hais rau Lifewire hauv kev xam phaj email.
"Piv txwv li, tsis yog yuav tsum muaj ntau qhov ntau thiab tsawg rau nplooj ntawv web, xws li hauv, ib qho rau siv hauv xov tooj, ib qho rau ntsiav tshuaj," nws hais tias, "yog tias koj tuaj yeem nce qhov 1080p duab rau 2k. los yog 4k thiab cov duab hauv xov tooj ntawd rau lub ntsiav tshuaj thiab 1080p, koj tau dheev txo cov duab xav tau los ntawm 6 mus rau 2."
"Koj tseem yuav txuag cov ntaub ntawv qhov chaw xav tau los ntawm cov ntaub ntawv loj 2k thiab 4k yog li yuav txo koj cov ntaub ntawv tag nrho qhov loj me uas xav tau los ntawm 70-90%."
Tsis yog rau TV
Duab upscaling tseem tuaj yeem ua kom cov duab zoo dua thiab tuaj yeem pab nrog kev kho mob. Cov neeg tsim kho software hais tias kev nce qib tuaj yeem ua rau muaj kev daws teeb meem ntawm cov duab yam tsis muaj kev puas tsuaj rau qhov zoo.
Tab sis, Matic Broz, tus tsim ntawm lub vev xaib thaij duab Photutorial, hais rau Lifewire hauv kev xam phaj email tias cov txiaj ntsig tiag yog nyob ntawm cov software siv.
"Tsis ntev los no, AI tau pom nws txoj hauv kev rau kev txhim kho cov duab, txawm tias kuv tsis txaus siab rau nws tam sim no," nws ntxiv.
Broz hais tias qhov zoo tshaj plaws upscaling software nws tau siv yog AI Image Enlarger los ntawm Vance AI.
"Txawm tias lawv 8x duab upscaler tsis qhia lub suab nrov (uas yog 64x nce hauv kev daws teeb meem), "nws hais. "Kuv cia siab tias cov algorithms tsuas yog ua tau zoo dua nyob rau xyoo tom ntej, tso cai rau kev nce qib loj dua."
Rau cov kws yees duab tseem, Broz tau hais tias nws yog ib lo lus nug qhib seb cov duab upscalers puas tsim nyog.
"Lub koob yees duab tsim tawm tas li txhim kho qhov kev daws teeb meem ntawm lub koob yees duab sensors, tam sim no txawm tias muaj 100MP + daws teeb meem," nws hais ntxiv. "Kuv tus kheej, kuv tau siv 24MP thiab txog 50MP, thiab kuv tsis tau xav tias yuav xav tau cov duab loj dua, tsis yog rau cov ntawv loj."
