A segmentation map yog ib feem ntawm lub dav hlau. Txhua cheeb tsam sawv cev rau ib yam khoom lossis ib cheeb tsam tshwj xeeb ntawm daim duab. Xav txog qhov chaw random Y = (ys)s∈Λ,qha ys ∈ S. Lub sij hawm zoo li P(Y |X) qauv cov qib grey faib ntawm cov pixels uas tau muab rau hauv chav kawm lossis cheeb tsam.
Kuj paub yog, dab tsi yog segmentation ntawm ib daim duab?
Hauv computer vision, duab segmentation yog tus txheej txheem ntawm partitioning ib tug digital duab rau hauv ntau ntu (pawg pixels, tseem hu ua duab khoom). Lub hom phiaj ntawm segmentation yog kom yooj yim thiab/los yog hloov tus sawv cev ntawm ib duab rau hauv ib yam dab tsi uas muaj ntsiab lus ntau dua thiab yooj yim rau kev txheeb xyuas.
Ib yam li ntawd, segmentation hauv kev kho cov duab ua dab tsi? Kev Kho Mob Duab Segmentation . Kev Kho Mob Duab Segmentation yog cov txheej txheem ntawm tsis siv neeg lossis ib nrab tsis siv neeg tshawb pom ntawm ciam teb hauv 2D lossis 3D duab . Tsis tas li ntawd, ntau yam kev hloov pauv (X-ray, CT, MRI , microscopy, PET, SPECT, Endoscopy, OCT, thiab ntau ntxiv) yog siv los tsim cov duab kho mob.
Yog li ntawd, cov txheej txheem segmentation sib txawv yog dab tsi?
Qhov nrov cov txheej txheem siv rau duab segmentation yog: thresholding method, edge detection based cov txheej txheem , cheeb tsam raws cov txheej txheem , pawg raws li cov txheej txheem , dej ntws raws cov txheej txheem , ib nrab sib npaug sib npaug raws li thiab cov khoom siv neural network raws li cov txheej txheem lwm.
EDGE raws li segmentation yog dab tsi?
Ntug Based Segmentation . Duab processing yog ib hom kev ua cov ntaub ntawv uas cov tswv yim yog ib qho duab , xws li thav duab video; cov zis tsis tas ib duab , tab sis tuaj yeem ua tau ib txheej ntawm cov yam ntxwv muab cov ntaub ntawv hais txog lub duab [152].

Daim ntawv qhia ncuav qab zib piav qhia nrog piv txwv yog dab tsi?
Cov kab kos ncuav qab zib yog siv hauv kev tuav cov ntaub ntawv thiab yog cov kab kos kab sib faib ua ntu uas txhua tus sawv cev rau tus nqi. Daim duab ncuav qab zib tau muab faib ua ntu (lossis 'slices') los sawv cev rau qhov sib txawv ntawm qhov ntau thiab tsawg. Piv txwv li, nyob rau hauv daim ntawv qhia ncuav qab zib no, lub voj voog sawv cev rau tag nrho cov chav kawm
Dab tsi yog qhov txawv ntawm daim duab radar thiab daim ntawv qhia khoom?
Cov kab kos duab yog tsim los tso saib cov ntaub ntawv ua lag luam. Radar kab kos yog qhov zoo tshaj plaws rau kev qhia qhov tseem ceeb txheeb ze rau qhov chaw nruab nrab thiab yog qhov tsim nyog rau kev qhia tshwj xeeb rau qhov sib txawv
Dab tsi yog qhov txawv ntawm daim ntawv pov thawj tus kheej thiab daim ntawv pov thawj CA?
Qhov kev ua haujlwm tseem ceeb ntawm daim ntawv pov thawj tus kheej kos npe thiab daim ntawv pov thawj CA yog tias nrog tus kheej kos npe, tus browser feem ntau yuav muab qee yam yuam kev, ceeb toom tias daim ntawv pov thawj tsis tau muab los ntawm CA. Ib qho piv txwv ntawm qhov yuam kev daim ntawv pov thawj tus kheej tau pom nyob rau hauv lub screenshot saum toj no
Dab tsi yog daim ntawv pov thawj hauv daim ntawv tshawb fawb?
Kev xav ntawm daim ntawv lees paub yog qhov tseem ceeb hauv kev tshawb nrhiav. Ib 'kev tshawb fawb warrant' yog li hais txog txoj hauv kev uas peb cov ntaub ntawv txhawb nqa cov lus thov uas peb ua. Daim ntawv lees paub txuas peb lub ntsiab lus tseem ceeb rau kev kawm, cov ntaub ntawv thiab kev tshuaj xyuas thiab cov lus thov peb ua thaum kawg
Cov ntaub ntawv txuas ntxiv rau daim ntawv nthuav qhia yog dab tsi?
Cov ntaub ntawv nthuav dav dav dav thiab lawv cov ntaub ntawv tawm tswv yim suav nrog XLSX (Microsoft Excel Qhib XML Spreadsheet), ODS (OpenDocument Spreadsheet) thiab XLS (Microsoft Excel Binary File Format)
