Super Pixel Segmentation Txoj Kev Ua Raws Li Ntawm Qhov Ncauj Lub Neej Gradient

Nov 17, 2017

1.1 Cov dej hiav txwv

1.2 Raws li txoj haujlwm hloov

1.3 Turbopixels txoj kev

1.4 SLIC txujci


2. Sib piv ntawm kev sim

Yuav kom nkag siab ntxiv txog kev ua tau zoo ntawm ob peb lub suab pixel feem ntau, cov ntaub ntawv no tau ua ib qho kev sib piv hauv Berkeley qauv qhia cov qauv ntaub ntawv, qhov pov thawj algorithm nrog entropy tus nqi (ER) Ncut- (Ncut- B) su-perpixel lattice (SL ) Turbopixels (TP) thiab SLIC ntawm txhua daim duab loj yog 321 x 481, muab faib rau txog 200 ib qho pixel pixel,


Raws li pom hauv daim duab 10 qhia tau tias ER algorithm tau khaws cov duab lus ntug, tiam sis tus pixel zoo lus tsis zoo, txhua qhov duab segmentation sij hawm yog txog 1.16sNcut- B algorithm tau zoo tswj cov duab ciam, thiab nrog nce tus naj npawb ntawm super pixels, pixels super pixel yuav ntau dua, tab sis lub sij hawm ntawm cov duab segmentation ntev, qhov loj ntawm 321 x 481 duab rau 200 tus ua haujlwm ceev ntawm super pixels nyob ib ncig ntawm 2min SL algorithm yog sai dua li ntawm txog 0.36 yuav ua tau muab faib ua duab grid, tab sis qhov zoo ntawm qhov segmentation tau zoo nws lub tswv yim ciam teb daim ntawv qhia ntawm TP thiab SLIC algorithm tuaj yeem tsim cov lus qhia thiab cov ntsiab lus pixels superb tiam sis, tus qauv ntawm TP ciam nyob tsis zoo,

SLIC los ntawm tus ciam teb kom ceev thiab super pixel puab qhov kev luj xyuas dua, piv nrog cov kev xav hauv lub ntsej muag ua rau kev nco 3.00GB processor Intel Core 2 tshuab, lub sij hawm sib piv ntawm cov ntau ntau pixel segmentation algorithm raws li qhia hauv lub rooj 1.
