Kev tshawb nrhiav txheej xwm Ntawm Super Pixel Daim Ntawv Thov

Nov 17, 2017

Lub tswv yim ntawm super pixels nyob rau hauv qhov ntxov tshaj plaws hauv 2003 los ntawm Keeb Kwm thiab lwm tus, cov txheej txheem pixel pixel rau extract duab xaav hauv cov cheeb tsam muaj ntsiab lus, yuav siv los hloov cov pixel grid txhim tsa, siv super pixels siv pixel lag luam, uas twb muaj lawm pixel li algorithm los txhim kho qee yam ntawm cov ntsiab lus tau rau 10 xyoo dhau los.


Kev tshawb fawb ntawm pixel pixel tau tsim tawm sai heev hauv tsev thiab txawv teb chaws, tau dhau los ua ib qho tseem ceeb hauv kev tshawb fawb ntawm kev tshawb pom computer rau ntau daim ntaub ntawv nyob rau hauv cov duab segmentation, muaj ntau lub segmentation algorithm raws li graph theory, xws li Ncut, nws cov nqi yuav nce cov nodes hauv lub teeb thiab ua kim, vim tias qhov algorithm yuav txwv qhov loj ntawm daim duab loj rau qee qhov kev siv, xws li electron micrographs ntawm mitochondria segmentation, daim duab loj loj, duab segmentation raws li pixel grid yog qhov nyuaj, lub Cov duab pixels nyob ib ncig ntawm lub pixel aggregation siv SLIC algorithm, ces txhua tus pixel ua txhua qhov ntawm lub teeb ua duab segmentation, nws tuaj yeem txo qhov tsis yooj yim ntawm cov duab, lub segmentation tiav niam txiv yooj yim.


Raws li pom hauv daim duab 11, siv SLIC tus qauv saib xyuas, qhov loj loj 3D daim duab segmentation rau billions ntawm pixels, thiab algorithm yog tsis muaj qhov nyuaj, txo cov kev cai nco, muaj peev xwm ho txhim kho qhov kev kawm ntawm Kohli li al. Yuav kom daws tau qhov teeb meem ntawm yuav ua li cas thiaj li yuav raug xa mus rau ib qho ntawm cov ntawv cim nrog lub cim tib yam.

Nyob rau hauv tib neeg kev ntsuas, Mori li al. Thawj daim duab muab faib ua cov blocks ntawm pixels lossis loj dua, ntes thiab nrhiav cov contour ntawm tib neeg lub cev pob qij txha thiab nquas, thiab tom qab ntawd ces tag nrho cov seem hauv lub cev nrog nrog Mori super pixel segmentation pretreatment, pab txoj kev nrhiav cov qauv hauv daim duab ntawm qhov ua tau zoo thiab qhov tseeb, thiab hauv cov duab zoo li qub nyob hauv tib neeg qhov kev ntsuas siab tau tiav zoo, raws li tau hais hauv daim duab 12.

Nyob rau hauv lub tshav pob ntawm phiaj nrhiav, Wang li al. Pom ib yam khoom nrhiav algorithm siv hyper pixel rau extract cov ntaub ntawv los ntawm cov kev xav ntawm theem nruab nrab kev pom.


Lawv siv tus pixel super zoo li kev saib xyuas kev ntxub ntxaug ua tus neeg tshawb nrhiav qhov txawv thiab cov keeb kwm yav dhau los ntawm kab theem kab theem intermediate kab. Tom qab ntawd, qhov kev taug qab ua haujlwm pauv mus ntsuas ib qho kev ntseeg keeb kwm yav dhau los, thiab tus neeg tuaj sib tw tau zoo tshaj plaws yog tau los ntawm qhov ntau tshaj qhov kev ntsuam xyuas posteriori.


Qhov kev tshawb nrhiav algorithm tuaj yeem ua nrog kev sib deev, lub hom phiaj nrhiav hauv kev ua haujlwm nyob rau hauv lub sijhawm cais tawm thiab kev tso tawm, raws li qhia hauv daim duab 13 Zhou li al. Cov txheej txheem ntawm kev ua kom ceev nrooj ntawm pixel lossis lub hom phiaj thiab keeb kwm yav dhau, tus algorithm muaj qhov kev ua zoo thiab kev ua haujlwm siab ntawm Liu uas pom txog kev tsheb ntawm ntau lub tsheb hauv lub ntiaj teb tiag hauv kev yees duab , cov ntaub ntawv tseem ceeb yog nkag tau rau hauv pixels super, zoo qhov daws qhov teeb meem txhaum cai thiab hla kev hla ntawm ntau lub tsheb.


Wang li al Tshawb nrhiav qhov teeb meem nrhiav cov teeb meem los ntawm kev tshawb cov super pixels raws li cov ntaub ntawv pom tau nyob ib ncig ntawm lub hom phiaj, thiab npaj siab rau ib tug qauv zoo li ntawm ob peb yam

Lub algorithm zoo dua li lwm cov algorithms ntawm cov khoom deformation thiab occlusion

Kuj yuav siv tau rau lwm yam ntawm tus duab pixel duab ua haujlwm ntxiv, Hoob ho. Super pixels siv nyob rau hauv cov duab scene classification, duab segmentation rau super pixel blocks, thiab duab SIFT feature extraction, tsim ntawm contextual visual descriptor, thiab siv qhov chaw hauv Pyramid sawv cev rau cov duab thiab kev faib tawm txujci.


Tighe li al. Applied super pixel rau scene tivthaiv tsom, thiab npaj siab yooj yim, tsis parametric thiab npaum duab tsom xam txuj. Fulkerson li al. Piav txog txoj kev nrhiav lub hom phiaj thiab qhov segmenting hom kawm uas yog siv pixel hauv duab. Cov kev sim ua rau ntawm Graz 02 thiab PASCAL VOC 2007 datasets zoo dua li ntau txoj kev xaiv cov duab segmentation.
