Hais txog kev ceev, HoG zoo li ceev tshaj plaws algorithm , ua raws li Haar Cascade classifier thiab CNNs. Txawm li cas los xij, CNNs hauv Dlib nyiam qhov tseeb tshaj plaws algorithm . HoG ua tau zoo heev tab sis muaj qee qhov teeb meem txheeb xyuas lub ntsej muag me me. HaarCascade Classifiers ua nyob ib ncig ntawm li zoo as HoG tag nrho.
Ib yam li ntawd ib tug yuav nug, uas algorithm yog siv rau kev kuaj lub ntsej muag?
Nrov paub algorithms suav nrog cov ntsiab lus tseem ceeb ntawm kev tsom xam siv eigenfaces, kev txheeb xyuas kab sib cais, cov kab ntawv elastic sib piv siv Fisherface algorithm , tus qauv Markov zais, kev kawm multilinear subspace siv tensor sawv cev, thiab cov neuronal txhawb kev sib txuas sib txuas.
Mtcnn face detection yog dab tsi? MTCNN - Ib txhij Kev Ntsuas ntsej muag & thaj chaw MTCNN (Multi-task Cascaded Convolutional Neural Networks) yog ib qho algorithm uas muaj 3 theem, uas kuaj pom cov thawv khi ntawm ntsej muag hauv ib daim duab nrog rau lawv 5 Point ntsej muag Cov cim (txuas mus rau daim ntawv).
Tsuas yog li ntawd, lub ntsej muag nrhiav kom pom algorithm ua haujlwm li cas?
Ib txwm algorithms suav nrog kev paub lub ntsej muag los ntawm kev txheeb xyuas ntsej muag nta los ntawm extracting nta, los yog landmarks, los ntawm cov duab ntawm lub ntsej muag . Piv txwv li, rho tawm ntsej muag nta, ib algorithm tuaj yeem txheeb xyuas cov duab thiab qhov loj ntawm lub qhov muag, qhov loj ntawm qhov ntswg, thiab nws qhov chaw txheeb ze nrog lub qhov muag.
Lub koob yees duab ntes ntsej muag li cas?
Kev kuaj pom lub ntsej muag . Hmoov zoo, ntsej muag muaj ib co yooj yim recognizable nta uas koob yees duab tuaj yeem xauv rau; ob lub qhov muag, qhov ntswg, thiab lub qhov ncauj. Los ntawm muaj peev xwm ntes a ntsej muag hauv qhov scene, lub koob yees duab tuaj yeem tsom nws autofocus ntawm tus neeg ntawd ntsej muag kom ntseeg tau tias nws yog qhov tseem ceeb hauv kev tsom mus rau hauv daim duab.

Qhov kev pabcuam AWS qhov twg yog qhov zoo tshaj plaws rau cov ntaub ntawv thaub qab rau lub sijhawm ntev?
Amazon S3 Glacier yog qhov ruaj ntseg, ruaj khov, thiab tsis tshua muaj nqi huab cia kev pabcuam rau kev khaws cov ntaub ntawv thiab thaub qab mus ntev. Cov neeg siv khoom tuaj yeem ntseeg tau khaws cov ntaub ntawv loj lossis me me rau tsawg li $ 0.004 ib gigabyte ib hlis, ib qho kev txuag tseem ceeb piv rau cov kev daws teeb meem hauv tsev
Dab tsi yog qhov zoo tshaj plaws algorithm rau kev soj ntsuam kev xav?
Kev soj ntsuam kev xav yog cov cuab yeej zoo sib xws uas siv los txheeb xyuas cov kev xav ntawm cov neeg siv khoom thiab muaj ntau lub algorithms tuaj yeem siv los tsim cov ntawv thov rau kev soj ntsuam kev xav. Raws li tus tsim tawm thiab ML cov kws tshaj lij SVM, Naive Bayes thiab qhov siab tshaj plaws entropy yog qhov zoo tshaj plaws saib xyuas tshuab kev kawm algorithms
