Itekhnoloji yokufumanisa isiphene selaphu elingalukwanga

Amalaphu angalukwanga ahlala esetyenziswa ngokubanzi njengezinto ezisetyenziswayo zonyango ezinje ngeemaski zotyando, iminqwazi yomongikazi, kunye neekepusi zotyando kwimveliso.Umgangatho wezinto ezichithwayo zonyango zixhomekeke ikakhulu kumgangatho weempahla ezingalukwanga.Ngenxa yokuba imveliso kunye nenkqubo yokuthutha amalaphu angalukwanga ayinakuqinisekisa ukucoceka ngokupheleleyo kokusingqongileyo, kwaye bona ngokwabo banamandla okubhengeza i-electrostatic adsorption, bahlala bebhengeza ukungcola okuncinci emoyeni.Ngoko ke, izinto zangaphandle zinokuba khona kwiindawo ezimbalwa kakhulu zeelaphu ezingalukwanga.Isixhobo selaphu esingalukwanga esifundwe kweli nqaku sisetyenziselwa ukuveliswa kweemaski, Emva kokuhlalutya iisampulu zesiphene ezikhethiweyo, kwafunyaniswa ukuba ubungakanani bezinto zangaphandle, ezifana nezinambuzane kunye neenwele, ziphezulu.Ubukho besi siphene bukhokelela ngokuthe ngqo kumgangatho ophantsi weemveliso ezilandelayo, kwaye iimveliso ezineziphene zithintelwe ngokungqongqo ukuba zingene kwimarike.Ke ngoko, abavelisi kufuneka basuse ezinye zezi ziphene, kungenjalo kuya kubangela ilahleko enkulu yezoqoqosho.

Okwangoku, uninzi lweenkampani ezinkulu kwishishini zisebenzisa izixhobo zokuhlola ezibonwayo ezivela kumazwe angaphandle ukuze kubonwe isiphene.Nangona iziphumo zintle, ezi zixhobo zidla ngokubiza imali eninzi kunye nokugcinwa kwazo, kwaye azifanelekanga ukuba zisetyenziswe ngamashishini amancinci kunye neendibano zocweyo.Uninzi lweenkampani ezincinci e-China zisasebenzisa uhlolo olubonakalayo lwencwadi oluqhelekileyo lokuhlola iziphene.Le ndlela ilula ngokwentelekiso, kodwa ifuna uqeqesho olude lwabasebenzi, ukusebenza kakuhle okuphantsi kunye nokuchaneka, kwaye ichithe abantu abaninzi, eyinkcitho enkulu kulawulo lweshishini.Kwiminyaka yakutshanje, intsimi yokuchongwa kwesiphene iphuhliswe ngokukhawuleza, kwaye abanini bamashishini ngokuthe ngcembe basebenzisa itekhnoloji entsha yokutshintsha iindlela zemveli zokuhlola okubonwayo.

Ukususela kumbono weendlela zokuphuhliswa kweshishini, ukuyila isixhobo sokufumanisa ngokuzenzekelayo esinokuthi sifumane kwaye sihlalutye imifanekiso enesiphene kwinkqubo yokuvelisa amalaphu angalukiweyo yindlela eyimfuneko yokukhuthaza uphuhliso lwemveliso, ukuqinisekisa umgangatho wemveliso, kunye nokunciphisa iindleko zabasebenzi.Ukusukela ngeminyaka yoo-1980s, iinjineli ezininzi zizamile ukusebenzisa ulwazi olufanelekileyo lombono wekhompyuter ukuze kufunyanwe isiphene samalaphu angalukwanga.Olunye uphando lusebenzise iindlela zokuhlalutya ukuthungwa ukubonisa iziphene kunye nokufikelela ekubhaqweni kwesiphene, ngelixa abanye basebenzise abaqhubi bokubona umphetho ukuqala ukumisela i-contour yesiphene kwaye babeke imiqobo esengqiqweni esekwe kulwazi lweenkcukacha-manani zegreyscale ukufezekisa ukubonwa kwesiphene, Kukho nezifundo ezisebenzisa i-spectral. iindlela zokuhlalutya ukufumanisa iziphene ezisekelwe kwi-texture periodicity ephezulu yamalaphu.

Ezi ndlela zingentla zifezekise iziphumo ezithile zesicelo kwiingxaki zokufumanisa isiphene, kodwa kusekho imida ethile: okokuqala, imilo kunye nobukhulu beziphene kwiindawo zokuvelisa ngokwenene ziyahluka.I-algorithms yokufumanisa i-defect esekelwe kumatshini wokufunda kunye nolwazi lwamanani lufuna ukuseta imida esekelwe kulwazi lwangaphambili, olungenakusebenza kuzo zonke iziphene, okubangelwa ukungonelanga kokuqina kwale ndlela.Okwesibini, iindlela zombono zekhompyuter zeSintu zihlala zicotha ukuphumeza kwaye azikwazi ukuhlangabezana neemfuno zexesha lokwenyani lokuvelisa.Ukususela kwi-1980, intsimi yophando lokufunda ngomatshini iphuhliswe ngokukhawuleza, kwaye ukusetyenziswa kolwazi olufanelekileyo kuye kwaqhuba ukuphuhliswa kwamashishini amaninzi.Izihloko ezininzi zophando zibonise ukuba ukusetyenziswa kwe-algorithms yokufunda koomatshini njenge-BP neural network kunye ne-SVM ekubhaqweni kwesiphene selaphu siyasebenza.Ezi ndlela ziqinisekisa ukuchaneka kokuchongwa okuphezulu kunye neqondo elithile lokuqina, kwaye akunzima ukufumanisa ngokuhlalutya ngokucokisekileyo inkqubo yoqeqesho lokufunda koomatshini, Ukusebenza kolu hlobo lwe-algorithm ngokuyintloko kuxhomekeke ekukhethweni kweempawu zencwadi yesiphene.Ukuba iimpawu zemanyuwali aziphelelanga okanye zicalula ngokwaneleyo, ukusebenza kwemodeli kuya kuba mbi.

Ngophuculo oluqhubekayo lwamandla ekhompyuter kunye nophuhliso olushushu lwethiyori yokufunda nzulu kwiminyaka yakutshanje, abantu abaninzi baye baqala ukusebenzisa ukufunda okunzulu ekubhaqweni kweziphene.Ukufunda nzulu kunokuphepha ngokufanelekileyo ukungaphelelanga kweempawu ezenziwe ngesandla kwaye kunokufumanisa ukuchaneka okuphezulu.Ngokusekwe kolu qwalaselo, eli nqaku lisebenzisa umbono wekhompyuter kunye nolwazi olunzulu olunxulumene nokufunda ukuyila inkqubo yokufumanisa ilaphu engalukiweyo ngokuzenzekelayo, ephucula ngokufanelekileyo ukuchongwa kokuchaneka kweziphene kwaye inokuqina okuhle.
