Niaj hnub nimno computer tsis pom kev. Paub tab thiab computer tsis pom kev technology. Programming Computer tsis pom kev nyob rau hauv nab hab sej

Yuav ua li cas los qhia ib lub computer to taub dab tsi yog xwm nyob rau hauv cov duab los yog cov duab? Qhov no yog nkawd yooj yim, tab sis rau ib tug computer no yog ib tug matrix uas muaj zeros thiab sawv daws yuav uas koj xav mus extract ntaub ntawv tseem ceeb.

Yuav ua li cas yog computer tsis pom kev? Nws yog ib lub peev xwm "saib" koj lub computer

Vision - yog ib tug tseem ceeb ntawm cov ntaub ntawv rau tus neeg siv nws, peb tau, raws li ntau yam kev kwv yees, los ntawm 70 mus rau 90% ntawm tag nrho cov ntaub ntawv. Thiab, ntawm chav kawm, yog hais tias peb xav tau los ua ib tug ntse tsheb, peb yuav tsum tau siv tib lub kev txawj ntse thiab lub computer.

Qhov teeb meem ntawm computer tsis pom kev yuav tau teev kom meej meej heev. Yuav ua li cas yog "saib"? Nws yog to taub hais tias qhov twg muaj yog los ntawm kev saib. Uas xaus qhov sib txawv ntawm lub computer tsis pom kev thiab tib neeg tsis pom kev. Vision rau peb - nws yog ib qhov chaw ntawm kev paub txog lub ntiaj teb no, raws li zoo raws li ib tug qhov chaw ntawm metric ntaub ntawv - uas yog, muaj peev xwm to taub txog cov ncua kev thiab ntau thiab tsawg.

Semantic ntsiav duab

Nrhiav nyob rau daim duab, peb yuav piav qhia txog nws los ntawm ib tug xov tooj ntawm cwj pwm, thiaj tau speak, extract semantic ntaub ntawv.

Piv txwv li, saib daim duab no, peb yuav hais tias nws yog nraum zoov. Yuav ua li cas yog lub nroog tsheb. Hais tias muaj tsheb. peb yuav twv hais tias qhov no yog South-East Asia rau lub configuration ntawm lub tsev thiab hieroglyphics. Lub portrait ntawm Mao Zedong to taub hais tias qhov no yog Beijing, thiab yog hais tias leej twg pom nyob video los yog nws tus kheej lawm muaj, yuav twv hais tias qhov no yog lub npe nrov Tiananmen Square.

Yuav ua li cas peb yuav hais ntau txog daim duab, pom nws? Peb yeej paub tej khoom nyob rau hauv cov duab, hais tias, muaj cov neeg nyob ntawm no ze zuj zus - laj kab. Ntawm no umbrellas, uas tsev zog. Cov no yog cov piv txwv ntawm cov chav kawm ntawv yog ib qho tseem ceeb cov khoom, uas yog koom nyob rau hauv kev tshawb fawb rau lub caij.

Tseem peb muaj peev xwm kawm ib txhia ntawm cov yam ntxwv los yog cwj pwm ntawm cov khoom. Piv txwv li, ntawm no peb yuav txiav txim hais tias qhov no yog tsis yog ib tug portrait ntawm ib tug zoo tib yam suav, namely, Mao Zedong.

Raws li lub tsheb yuav tsum tau txiav txim hais tias nws yog ib tug tsiv kwv, thiab nws yog ib qho nyuaj, uas yog tsis deformed thaum lub sij hawm lub zog. Hais txog tus chij yuav tau hais tias nws tej khoom, lawv kuj tsiv, tab sis lawv yuav tsis nyuaj, lossi deformed. Thiab nyob rau hauv lub scene muaj yog cov cua, uas yuav tsum tau txiav txim los ntawm kev tsim tus chij, thiab muaj peev xwm txawm txiav txim cov kev taw qhia ntawm cov cua, piv txwv li, nws yog tshuab los ntawm sab laug mus rau sab xis.

Lub ncua kev thiab lengths nyob rau hauv computer tsis pom kev

Heev tseem ceeb yog lub metric cov lus qhia txog computer tsis pom kev science. Qhov no yog tag nrho cov hom ntawm mus. Piv txwv li, rau cov Rover yog tshwj xeeb yog ib qho tseem ceeb vim hais tias cov pawg yog los ntawm lub ntiaj teb hais txog 20 feeb thiab teb raws li ntau. Raws li, qhov link muaj thiab rov qab - 40 feeb. Thiab yog hais tias peb ua ib lub hom phiaj rau kev tshem commands ntawm lub ntiaj teb, koj yuav tsum noj cov tshuaj no mus rau hauv tus account.

Ntse kev lub cuab yeej ntawm computer tsis pom kev nyob rau hauv video ua si. Raws li cov kev yees duab, koj yuav tau tsim peb-dimensional cov qauv ntawm cov khoom, cov neeg, thiab cov duab nyob rau hauv tus neeg siv yuav muab lub peb-dimensional qauv ntawm lub zos. Thiab ces taug kev rau lawv.

computer tsis pom kev - ib tug es ntau yam. Nws yog zoo intertwined nrog rau ntau yam lwm yam sciences. Ib feem ntawm lub computer tsis pom kev Nws captures cov duab ua cheeb tsam thiab tej zaum kuj allocates computer tsis pom kev, dabneeg.

Analysis, qauv paub - cov kev mus rau lub creation ntawm superior txawj ntse

Cia peb kawm cov tswv yim nyias.

Duab ua - qhov no yog ib thaj chaw ntawm algorithms, nyob rau hauv uas lub tswv yim thiab tso zis - duab, thiab peb muaj nws ua ib yam dab tsi.

duab tsom xam - yog lub cheeb tsam ntawm lub computer tsis pom kev, uas tsom rua kev ua hauj lwm nrog ob tug-dimensional duab thiab ua cov lus xaus ntawm qhov no.

Txawv Recognition - ib tug paub daws teeb zauv kev qhuab qhia uas yeej pom tau tias cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov vectors. Uas yog, nyob rau kev nkag - vector thiab peb muaj ib yam dab tsi ua nrog nws. Nyob qhov twg lub vector yog, peb yog tsis yog li ntawd ib qho tseem ceeb kom paub.

Khoos phib tawj pom kev - nws muas thaum chiv thawj yog los cov qauv ntawm cov ob-dimensional dluab. Niaj hnub no cov cheeb tsam no tau ua nrug thiab nws yuav muab txhais raws li kev txaus sab ntawm tag nrho cov lub cev khoom ua, raws li nyob rau hauv cov duab. Hais tias yog, nws yog neeg ua hauj lwm ntawm cov khoom cua txawj ntse.

Nyob rau hauv thaum uas tig mus nrog computer tsis pom kev nyob rau hauv ib tug txawv kiag li teb, nyob rau hauv geodesy, photogrammetry tau hloov zuj zuj - ib qho kev ntsuas ntawm qhov kev ncua deb ntawm cov khoom nyob rau hauv ob-dimensional dluab.

Robots yuav "saib"

Thiab thaum kawg - qhov no yog tshuab tsis pom kev. Nyob rau hauv lub tshuab pom kev txhais tau tias ib lub zeem muag ntawm robots. Qhov ntawd yog qhov kev txiav txim siab ntawm ib co ntau lawm cov teeb meem. Peb yuav hais tias computer tsis pom kev - yog ib tug loj science. Nws combines ib co ntawm lwm yam science ib feem. Thiab thaum lub computer tsis pom kev tau txais tej kev daim ntawv thov, nws dhau mus ua ib lub tshuab tsis pom kev.

Khoos phib tawj pom kev thaj av ntawd muaj ib tug loj ntawm cov tswv yim daim ntawv sau npe. Nws yog txuam nrog rau cov automation ntawm ntau lawm. Thaum lub qhauj ua ntau npaum los hloov kev ceev zog los ntawm lub tshuab. Lub tshuab tsis tau nkees, tsis tsaug zog, nws muaj lus ua hauj lwm lub sij hawm, nws yog kam mus ua hauj lwm 365 hnub hauv ib lub xyoo. Yog li ntawd, siv lub tshuab ua hauj lwm, peb muaj peev xwm tau txais ib guaranteed tshwm sim ntawm ib tug tej lub sij hawm, thiab nws yog heev nthuav. Tag nrho cov kev pab raws qib muaj ib tug ntshiab siv rau computer tsis pom kev systems. Thiab muaj tsis muaj dab tsi zoo dua rau saib tau sai li sai tau rau hauv daim duab xwb nyob rau hauv lub xam nyob ntev.

Nyob rau hauv lub chaw pib ntawm lub ntiaj teb no kev ntse

Plus cov cheeb tsam - nws yog ib qho nyuaj! Ib tug tseem ceeb ib feem ntawm lub paj hlwb lub luag hauj lwm rau lub zeem muag, thiab nws yog ntseeg hais tias yog koj qhia koj lub computer mus "saib", uas yog, tag nrho cov kev siv computer tsis pom kev, nws yog ib tug ntawm lub hom phiaj ntawm tag nrho cov dag txawj ntse. Yog hais tias peb muaj peev xwm daws tau qhov teeb meem nyob rau hauv tib theem, feem ntau yuav nyob rau tib lub sij hawm, peb yuav daws tau qhov teeb meem ntawm cov kabmob AI. Qhov ntawd yog zoo heev! Los yog tsis zoo heev, yog tias koj saib, "Terminator 2".

Yog vim li cas yog tsis pom kev - nws yog ib qhov nyuaj? Vim hais tias cov duab ntawm lub tib lub nruas yuav txawv heev nyob rau lwm yam. Nyob ntawm seb tus kwv uas soj ntsiab lus zoo sib txawv.

Piv txwv li, ib tug thiab tib daim duab, coj los ntawm ces kaum sib txawv. Thiab yog dab tsi yog feem ntau nthuav nyob rau hauv lub daim duab tej zaum yuav ib lub qhov muag, ob lub qhov muag thiab ib tug ib nrab. Thiab nyob rau hauv lub ntsiab lus teb (yog hais tias cov duab ntawm tus txiv neej nyob rau hauv ib lub tsho nrog pleev xim rau ob lub qhov muag), lub qhov muag yuav ua tau ntau tshaj li ob.

Lub computer tseem tsis to taub, tiam sis nws "pom"

Lwm yam uas ua rau nws tsis yooj yim - nws yog lub teeb pom kev. Cov tib scene nrog sib txawv teeb pom kev zoo yuav zoo sib txawv. yam khoom me me muaj peev xwm sib txawv. Ntxiv mus, cov khoom ntawm cov tub kawm. Yuav ua li cas yuav koj hais txog ib tug txiv neej hais tias nws qhov siab ntawm 2 meters? Tsis muaj dab tsi. Tib neeg txoj kev loj hlob thiab tej zaum yuav 2.3 m, thiab 80 cm. Raws li nrog rau lwm yam khoom, txawm li cas los, yog khoom ntawm tib chav kawm ntawv.

Tshwj xeeb yog nyob khoom yauv ib tug ntau yam ntawm hom. Cov plaub hau cov neeg, ncaws pob, tsiaj txhu. Saib cov duab ntawm nees khiav, txiav txim dab tsi tshwm sim nrog rau lawv cov txoob thiab tus Tsov tus tw yog tsuas tsis yooj yim sua. Ib tug overlapping khoom nyob rau hauv ib tug duab? Yog hais tias koj tsij ib tug computer duab, txawm lub feem ntau haib tshuab nrhiav nyuaj rau muab txoj kev txiav txim.

Tom ntej no saib - nws yog ib tug neeg tsis paub. Ib txhia cov khoom, tsiaj txhu masquerading li cov ib puag ncig, thiab heev skillfully. Thiab tib me ntsis thiab coloring. Cuaj kaum, peb pom lawv, txawm hais tias tsis yeej ib txwm los ntawm afar.

Ib qho teeb meem - lub zog. Khoom nyob rau hauv tsab ntawv tsa suab unimaginable yauv deformation.

Muaj ntau ntawm cov khoom no zoo heev nce mus nce los. Ntawm no, piv txwv li, nyob rau hauv ob cov duab hauv qab no cov khoom ntawm lub "rooj zaum".

Thiab nyob rau qhov no koj yuav zaum. Tab sis qhia ib lub tshuab, xws li hais tias cov tej yam txawv nyob rau hauv zoo lawm, xim, khoom, txhua yam yog ib tug kwv "zaum" - yog heev yooj yim. Qhov no yog cov kev sib tw. Yuav kom integrate txoj kev computer tsis pom kev - yog los qhia ib lub tshuab los to taub, tsom xam, xav.

Kev koom ua ke ntawm computer tsis pom kev nyob rau hauv ntau yam platforms

Cov pawg ntawm cov computer tsis pom kev pib txeem ntau nyob rau hauv 2001, thaum nws tsim thawj lub ntsej muag ntes. Peb ua nws ob tug sau phau ntawv: Viola, Jones. Nws yog tus thawj ceev thiab txhim khu kev qha txaus algorithm, uas pom lub hwj chim ntawm lub tshuab kev kawm txoj kev.

Tam sim no computer tsis pom kev muaj txaus tshiab cov tswv yim daim ntawv sau npe - nrog paub txog tib neeg lub ntsej muag.

Tab sis kom paub txog tus txiv neej raws li nyob rau hauv qhov tsos - thaum random ces kaum, sib txawv teeb pom kev zoo tej yam kev mob - nws yog tsis yooj yim sua. Tab sis kom daws tau qhov teeb meem, los yog ib tug uas yog neeg sib txawv uas sib txawv teeb pom kev zoo los yog nyob rau hauv ib tug txawv teeb, uas zoo sib xws raws li nyob rau hauv cov duab nyob rau hauv lub passport, nws yog tau nrog ib tug high degree ntawm kev cog qoob loo.

ib tug passport yees duab yuav tsum tau kev lom zem ntau vim lub feature ntawm lub ntsej muag Vocabulary algorithms.

Piv txwv li, yog tias koj muaj ib tug biometric passport, nyob rau hauv ib co niaj hnub tshav dav hlau, koj yuav siv tau lub automatic passport tswj system.

Unsolved teeb meem ntawm computer tsis pom kev - lub peev xwm kom paub txog tej ntawv nyeem

Tej zaum ib tug neeg siv OCR system. Ib tug ntawm cov - ib tug Fine Nyeem ntawv, yog heev nrov nyob rau hauv RuNet system. Muaj ntau yam ntaub ntawv uas koj sau nyob rau hauv cov ntaub ntawv, lawv yog zoo kawg nkaus luam, cov ntaub ntawv yog lees paub los ntawm lub system zoo heev. Tab sis nrog rau tej ntawv nyeem nyob rau hauv cov duab qhov teeb meem no yog heev npaum li cas. Qhov teeb meem no tseem nyob unsolved.

Ua si uas muaj computer tsis pom kev, tsab ntawv tsa suab capture

Cais loj cheeb tsam - yog lub creation ntawm peb-dimensional qauv thiab cov lus tsa suab capture (uas yog heev ntse los siv nyob rau hauv computer ua si). Cov kev pab thawj zaug, uas siv computer tsis pom kev - ib tug system ntawm kev sis raug zoo nrog cov computer siv gestures. Thaum nws tau tsim nws yog ib tug ntau ntawm tej yam uas qhib.

Lub algorithm yog tsim heev tsuas, tab sis mus rau configure nws coj mus tsim ib tug generator ntawm cov khoom cua dluab ntawm cov neeg kom tau ib tug lab cov duab. Supercomputer nrog lawv mus xaiv tus ciaj ciam ntawm lub algorithm, rau cov uas nws tam sim no ua hauj lwm zoo.

Yog tias ib tug lab cov dluab thiab lub lim tiam suav supercomputer lub sij hawm tau los mus tsim ib qho algorithm uas kov 12% ntawm cov muaj peev xwm ntawm ib tug processor thiab tso cai rau ib tug neeg mus rau perceive txoj hauj lwm nyob rau hauv lub sij hawm. Qhov no Microsoft Kinect system (2010).

Nrhiav rau cov dluab ntawm cov ntsiab lus tso cai rau koj mus upload duab rau lub cev, thiab cov kev tshwm sim ntawm nws yuav muab tag nrho cov duab nrog tib cov ntsiab lus thiab ua los ntawm cov tib kaum sab xis.

Piv txwv ntawm lub computer tsis pom kev: peb-dimensional thiab ob-dimensional maps yog tam sim no tau ua nrog nws. Maps rau navigation tsheb muaj tsis tu ncua tshiab raws li lub DVR.

Muaj yog ib tug database nrog billions ntawm geotagged duab. Los daus hauv daim duab nyob rau hauv lub database, koj yuav txiav txim qhov uas nws tau ua, thiab txawm nrog ib txhia xav. Ntawm cov hoob kawm, muab hais tias qhov chaw yog nrov txaus tias thaum ib lub sij hawm lub tourists thiab ua ib tug xov tooj ntawm cov duab ntawm lub cheeb tsam tau muaj.

robots yog qhov txhia chaw

Robotics nyob rau tam sim no lub sij hawm, qhov txhia chaw, tsis muaj nws nyob rau hauv txhua txoj kev. Tam sim no muaj cov tsheb uas muaj kev tshwj xeeb cov koob yees duab uas paub txog cov neeg taug kev thiab txoj kev tshwm sim mus rau kis commands rau tus neeg tsav tsheb (qhov no nyob rau hauv ib txoj kev ib qho computer program mus saib, yuav pab kom cov tsav tsheb). Thiab muaj ib tug tag nrho cia li robotic tsheb, tab sis lawv muaj peev xwm tsis tso siab tag nrho rau cov kev yees duab lub koob yees duab system tsis muaj tus siv ntawm ib tug loj npaum li cas ntawm cov lus qhia ntxiv.

Niaj hnub nimno cov koob yees duab - qhov no yog ib qho analogue koob yees duab obscura

Cia tus tham txog lub digital duab. Niaj hnub nimno cov koob yees duab yog cov txheej txheem ntawm nyob rau hauv lub hauv paus ntsiab lus ntawm cov koob yees duab obscura. Tsuas yog tsis lub qhov los ntawm kev uas lub teeb nkag mus rau hauv lub beam thiab npaj mus rau lub rov qab phab ntsa ntawm lub chamber ntawm cov kev kawm Circuit Court, peb muaj ib tug tshwj xeeb kho qhov muag hu ua lub lens. Nws tus kwv yog sau ib tug loj teeb beam thiab hloov nws thiaj hais tias tag nrho cov rays dhau los ntawm ib tug virtual taw tes rau hauv thiaj li yuav tau lub projection thiab tsim ib tug duab nyob rau hauv zaj duab xis los yog matrix.

Niaj hnub nimno cov koob yees duab (matrix) yog muaj li ntawm ib tug neeg hais - pixels. Txhua pixel yuav ntsuas lub zog ntawm lub teeb uas yog teeb meem rau lub pixel tag nrho, thiab muab ib cov zis tooj. Yog li ntawd, nyob rau hauv ib cov koob yees duab, peb tau txais es tsis txhob ntawm daim duab brightness set teeb ntsuam, ntes tau nyob rau hauv ib pixel - lub computer teb pom. Yog li ntawd, thaum cov duab peb pom no tsis ntws kab thiab meej nkhaus, thiab ib tug kab sib chaws ntawm cov dawb lias squares nyob rau hauv cov xim txawv - pixels.

Hauv qab no koj pom cov thawj cov duab nyob rau hauv lub ntiaj teb no.

Tab sis nyob rau hauv daim duab no yog tsis tau? Xim. Yuav ua li cas yog xim?

Puas siab puas ntsws xaav ntawm cov xim

Xim - qhov no yog dab tsi peb pom. Cov xim ntawm tus ib thiab tus qub tshaj plaws rau cov tib neeg thiab miv yuav tsum sib txawv. Txij li thaum peb (tib neeg) thiab tsiaj kho qhov muag system - lub zeem muag yog sib txawv. Yog li ntawd, cov xim - nws yog puas siab puas ntsws zoo ntawm peb lub zeem muag uas tshwm sim thaum tsom kwm cov khoom thiab lub teeb. Thiab tsis yog ib tug lub cev khoom teejtug uas yog tus kwv thiab lub teeb. Xim - yog lub txiaj ntsim ntawm tus sis ntawm lub teeb lub Cheebtsam, thiab cov scene ntawm peb qhov muag pom system.
