Daim ntawv tso cai daim ntawv lees paub qhov system feem ntau yog siv nyob rau hauv cov chaw nres tsheb ntse thiab cov tsheb sib tshuam. Nws yog ib qho tseem ceeb los txheeb xyuas cov ntaub ntawv tsheb. Niaj hnub no, peb yuav tham txog qee cov teeb meem uas tshwm sim thiab cov kev daws teeb meem ntawm daim ntawv tso cai daim ntawv lees paub qhov system.
Environmental factor yog lub ntsiab tseem ceeb cuam tshuam rau daim ntawv tso cai daim ntawv lees paub. Nyob rau hauv qhov sib txawv ambient teeb, kev ntes thiab ntes cov duab tsheb yuav raug cuam tshuam rau qee yam. Lub teeb txaus thaum nruab hnub, thiab lub teeb tsis muaj zog thaum hmo ntuj. Ntawd yog, thaum lub tsheb ceev ceev heev, video zoo ntawm cov duab dynamic tsis tuaj yeem lav.
Yog li, peb yuav tsum daws cov teeb meem no li cas thiab txhim kho kom pom tseeb ntawm daim ntawv tso cai daim ntawv lees paub?
Ua ntej tshaj plaws, peb tuaj yeem ntxiv cov ntse sau lub teeb kom daws tau qhov teeb meem ntawm lub teeb tsis txaus, thiab lub koob yees duab tuaj yeem ntes cov duab meej; thib ob, cov duab tuaj yeem ua ntej. Vim tias daim duab lees paub los ntawm daim ntawv tso cai muaj suab nrov ntau lossis daim ntawv tso cai raug thaiv, lub tsheb khiav. Cov duab uas tau tshwm sim yog qhov muag plooj thiab distorted, yog li nws yog qhov nyuaj rau kev siv qhov chaw algorithm. Yog tias lub algorithm tuaj yeem hloov mus rau ntau qhov chaw ib puag ncig nyuaj thiab cov xwm txheej tshwj xeeb, nws tuaj yeem txhim kho daim ntawv tso cai daim ntawv lees paub tus nqi.
