Qhov kev faib tawm qhov tsawg kawg nkaus yog siv txhawm rau faib cov duab tsis paub cov ntaub ntawv rau cov chav kawmuas txo qhov kev ncua deb ntawm cov duab duab thiab cov chav kawm hauv ntau qhov chaw. Qhov kev ncua deb txhais tau tias yog qhov ntsuas qhov sib xws kom qhov tsawg kawg nkaus qhov deb yog zoo tib yam rau qhov siab tshaj plaws zoo sib xws.
Yuav ua li cas cais qhov deb tsawg kawg nkaus ua haujlwm?
yam tsawg kawg-nruab deb-rau-txhais tau tias kev faib tawm A qhov chaw taws teeb sensing kev faib tawm qhov system uas qhov nruab nrab ntawm qhov chaw digital parameter yog xam rau pixels ntawm cov chav kawm paub, thiab cov pixels tsis paub yog ces muab rau cov chav kawm uas yog arithmetically ze tshaj thaum tus lej digital qhov tseem ceeb ntawm qhov sib txawv bands yog plotted
Nyob deb deb yog dab tsi?
Yam tsawg kawg ntawm kev kwv yees, ib txoj hauv kev ua kom haum tus qauv rau cov ntaub ntawv. Qhov teeb meem ze tshaj plaws ntawm cov ntsiab lus, qhov teeb meem algorithmic ntawm kev nrhiav ob lub ntsiab lus uas muaj qhov tsawg kawg nkaus ntawm cov ntsiab lus loj dua. Euclidean nrug, qhov tsawg kawg nkaus ntev ntawm ib qho nkhaus ntawm ob lub ntsiab lus hauv lub dav hlau.
Kev faib tawm parallelepiped yog dab tsi?
Tus parallelepiped classifier yog ib qho ntawm kev siv dav dav saib xyuas kev faib tawm algorithms rau ntau cov duabQhov chaw pib ntawm txhua qhov spectral (chav kawm) kos npe yog txhais hauv cov ntaub ntawv qhia, uas yog los txiav txim seb puas yog muab pixel hauv chav kawm lossis tsis.
Kev saib xyuas cov duab yog dab tsi?
Kev saib xyuas kev faib tawm yog raws li lub tswv yim uas tus neeg siv tuaj yeem xaiv cov qauv pixels hauv ib daim duab uas yog tus sawv cev ntawm cov chav kawm tshwj xeeb thiab tom qab ntawd coj cov duab ua softwaresiv cov no. chaw cob qhia raws li kev siv rau kev faib tawm ntawm tag nrho lwm cov pixels hauv daim duab.
