Tshaj tawm - ua tej zaum yuav xa mus rau: Duab kho kom zoo nkauj hauv kev yees duab. Audio editing software hauv suab. Differential GPS ncej - ua , ib qho kev txhim kho rau lub tshuab GPS uas txhim kho qhov tseeb. Finite element qauv cov ntaub ntawv post - ua , software uas ua rau lub computer xam tso zis yooj yim to taub.
Hais txog qhov no, lub ntsiab lus ntawm kev ua haujlwm tom qab yog dab tsi?
Tom qab ua tiav yog txheej txheem ntawm kev kho cov ntaub ntawv ntes los ntawm lub koob yees duab thaum noj cov duab los txhim kho cov duab . Zoo dua cov ntaub ntawv ntes thaum txhaj cov duab zoo dua yog qhov ua tau zoo dua.
Ib yam li ntawd, vim li cas peb thiaj li ua ntej cov ntaub ntawv? Lub ntiaj teb tiag data yog feem ntau ua tsis tiav, tsis sib xws, thiab / lossis tsis muaj qee yam kev coj cwj pwm lossis kev nyiam, thiab yog yuav muaj ntau yam yuam kev. Cov ntaub ntawv preprocessing yog ib txoj kev pov thawj ntawm kev daws cov teeb meem no. Cov ntaub ntawv ua ntej npaj raw cov ntaub ntawv rau kev ua haujlwm ntxiv.
Kuj kom paub, dab tsi yog tom qab ua cov teebmeem?
Tshaj tawm - ua tso cai teebmeem siv uas yuav tsum tau paub txog tag nrho cov duab (vim ib txwm txhua yam khoom 3D tau muab tso rau hauv kev sib cais). Xws li teebmeem suav nrog: Ambient occlusion (HBAO, Screen space ambient occlusion (SSAO, reflections), thiab lwm yam.
Post processing nyob rau hauv cov duab ua yog dab tsi?
Tshaj tawm - ua tej zaum yuav xa mus rau: Duab kho kom zoo nkauj hauv kev yees duab. Audio editing software hauv suab. Differential GPS ncej - ua , ib kev txhim kho rau GPS systems uas txhim kho qhov tseeb. Video ncej - ua , txoj kev siv hauv video ua thiab 3D graphics.

Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Dab tsi yog tus lej ncaj qha uas yuav tsum raug tshem tawm ntawm cov ntaub ntawv tshawb fawb kom ua raws li kev siv cov ntaub ntawv txwv?
Cov ntaub ntawv qhia ncaj qha hauv qab no yuav tsum raug tshem tawm rau PHI kom tsim nyog raws li cov ntaub ntawv txwv: (1) Cov npe; (2) Cov ntaub ntawv chaw nyob xa ntawv, tsis yog lub nroog lossis nroog, xeev, thiab ZIP code; (3) xov tooj; (4) fax xov tooj; (5) email chaw nyob; (6) social security naj npawb; (7) cov ntaub ntawv kho mob; (8) kev npaj kho mob
Thaum cov lus tau hla tawm cov ntaub ntawv kuaj xyuas feem ntau nthuav tawm cov ntawv sau thawj nrog kev pab ntawm dab tsi?
Infrared luminescence yog siv rau: Qhia tawm cov ntawv sau uas tau muab tshem tawm THIAB kuaj pom yog tias ob tus lej sib txawv tau siv rau hauv kev sau ntawv. Cov kws tshuaj xyuas cov ntaub ntawv feem ntau nthuav tawm cov ntawv sau thawj ntawm cov lus uas tau hla nrog kev pab ntawm: Infrared tawg
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
