Yintoni ebonwa yimodeli yokusika kwisixhobo

By Technical specialist

Imodeli yokusika ekwisixhobo ayiboni mntu, isihlangu, isilwanyana sasekhaya, okanye isitulo ngokwengqondo yomntu. Ifumana umelo lwamanani lomfanekiso kunye noqikelelo, i-pixel nge-pixel, yeyiphi indawo ekunokwenzeka ukuba ibe yeyomxholo ophambili. Imveliso yayo eluncedo yimaski: imephu engwevu enokuthi ibe ngumjelo ocacileyo wesiphumo.

Loo mahluko uchaza zombini isantya cutouts oluzenzekelayo kunye nemida yabo. Imodeli inokusebenzisa iipatheni ezibonakalayo ezifundwe ngexesha loqeqesho, kodwa ayazi injongo yakho. Into ebukhali ekufutshane nombindi inokubonakala ibalulekile; umphetho weglasi efipheleyo okanye umsonto okhululekileyo weenwele unokubonakala ngathi ngasemva.

Ukusuka kwifayile yomfanekiso ukuya kwigalelo lomfuziselo

Ifayile oyikhethayo kuqala kufuneka iguqulwe. Ifoto ecinezelweyo ayigqithiswanga ngqo kwimodeli njengebhloko yee-bytes zefayile. Umkhangeli zincwadi uyijika ibe ngamaphikseli ngobubanzi, ubude, kunye namaxabiso ombala.

Umbhobho wentelekelelo emva koko ulungiselela igalelo lobungakanani bomzekelo. Ngokuxhomekeke kwimodeli kunye nexesha lokusebenza, ukulungiswa kunokubandakanya:

• ukubuyisela ubungakanani bomfanekiso oqingqiweyo kwimilinganiselo imodeli elindelekileyo;
• ukucwangcisa ixabiso elibomvu, eliluhlaza, neliluhlaza njengetshaneli zamanani;
• ukulinganisa okanye ukuqhelanisa loo maxabiso;
• ukuwapakisha kwi-tensor, ifomathi yoluhlu olusetyenziswa yi-inference runtime.

Imilinganiselo echanekileyo kunye nemithetho yokulinganisa ixhomekeke ekuphunyezweni kwemodeli. Inqaku elibonakalayo elibalulekileyo lelokuba i-inference idla ngokusebenza ukusuka kumelo olulungisiweyo, hayi kwipixel yonke yomthombo kubungakanani bayo bokuqala.

Easy Background Remover iqhuba eli nyathelo lokungeniswa kwisikhangeli ngemodeli yokwahlulwa kwesixhobo. Ifayile yomfuziselo inokufuna ukukhutshelwa phambi kokusikwa kokuqala, kodwa indlela yokwenziwa komfanekiso iyilelwe ukuhlala kwindawo xa imodeli ilungile. Ukukhuphela imodeli sisicelo se-asethi; asiyonto ifanayo nokulayisha ifoto ekhethiweyo kwingqikelelo ekude.

Isiphumo sisimaski esifana nokuzithemba

Kwindawo nganye kwimveliso yayo, imodeli ivelisa ixabiso elinokutolikwa njengesifundo-esifana nesifundo okanye esifana nemvelaphi. Kuluncedo ukwenza umfanekiso woku njengomfanekiso ongwevu:

• ezimhlophe kuthetha ukugcina le ndawo;
• abamnyama kuthetha ukususa le ndawo;
• ngwevu kuthetha ukhuselo oluyinxenye okanye ukungaqiniseki kufutshane nomphetho.

Umkhangeli zincwadi uguqula loo mveliso ibe yimaski esebenzayo yealpha. Iiphikseli zombala woqobo zinokudityaniswa ngaphezulu kwebhodi yokujonga, ukuzaliswa okuqinileyo, igradient, okanye omnye umfanekiso. Ukuthunyelwa ngaphandle okubonakalayo kugcina imaski njengealpha endaweni yokupeyinta ibhodi yokukhangela kwifayile.

Amaxabiso athambileyo abalulekile. Ukuba lonke ixabiso lemaski liye lanyanzelwa ngoko nangoko ukuba libe mnyama okanye limhlophe, iinwele, uboya, imicu zelaphu, ukufiphala okushukumayo, kunye nemiphetho engagxiliyo inokuba nzima ngokungekho ngokwemvelo. Inxalenye yealpha inokugcina inguqu egudileyo. Iyakwazi ukuveza imiphetho yombala kwimvelaphi yakudala, yiyo loo nto isiphumo sisafanele ukujongwa.

Bubuphi ubungqina obubonakalayo obunceda imodeli

Imodeli yokwahlulahlula inokuzoba ngaphezulu kwesikhokelo esinye ngexesha elinye. Iimpawu ezinamandla zihlala ziquka:

• umahluko phakathi kwesihloko nemvelaphi;
• imida eqhubekayo ejikeleze into elawulayo;
• indibaniselwano eqhelekileyo yokumila, ukuthungwa, kunye nendawo;
• izikhokelo ezinzulu ezifana neeyantlukwano ekugxilwe kuzo; -imimandla ebonwayo idibene.

Akukho nanye kwezi zikhokelo isiqinisekiso. Ijacket emnyama ngokubhekiselele eludongeni olumnyama inikezela ngokungafaniyo komda obuthathaka. Isitulo esinezikhewu ezimxinwa sinokuqulatha imimandla yangasemva efana nale nto. Umva owenziwe ngasemva unokukhuphisana nowona mxholo ukuze kuqwalaselwe.

Imodeli yenza uqikelelo olungcono kwiipikseli ezikhoyo. Ayinakuphinda ifumane iinkcukacha ezingazange zithathwe ngumfanekiso.

Yintoni imodeli engayazi

Imodeli ayazi ngokuzenzekelayo ukuba yeyiphi into obufuna ukuyigcina xa kukho izifundo ezininzi. Akwaziwa ukuba iglasi yokusela ecacileyo ibalulekile kwezorhwebo, ukuba isithunzi sifanele sihlale siyinto yokwenene, okanye ukuba umtyana omncinane ngowengxowa.

Kananjalo ayifumani uguqulelo olufihliweyo lwesisombululo esiphezulu somthombo omfiliba. Iibhloko zokucinezela, iimbalasane ezisikiweyo, ukufiphala kwentshukumo, kunye neenkcukacha ezincinci kakhulu zinciphisa ubungqina obukhoyo. Ukwandisa i-zoom yokujonga kwangaphambili kwenza iipikseli zibe nkulu kwiscreen; ayidali ulwazi olungekhoyo.

Kungenxa yoko le nto “i-AI iyifumene” kwaye “umda ulungele ukupapasha” ngamabango ahlukeneyo. Ukufunyanwa kuqalisa ukuhlela. Uphononongo luyayigqiba.

Kutheni iinkcukacha ezibhityileyo nezicacileyo zinzima

Izinto ezibhityileyo zithatha ipixels ezimbalwa. Xa umfanekiso usenziwa ubungakanani bentsingiselo, ucingo oluyipixel enye okanye umsonto weenwele unokwenziwa iavareji kunye nemvelaphi ejikelezileyo. Izinto ezicacileyo zinzima ngenxa yesinye isizathu: umbala wabo obonakalayo uyingxenye yemvelaphi yakudala. Umda unokucaca kumntu oyiqondayo into, ngelixa ipateni ye-pixel ihlala ingaqondakali.

Izithunzi ezithambileyo zidala ukungacaci kwangabom. Umphetho wabo wangaphandle uphela ngokuthe ngcembe, kwaye akukho ndlela enye echanekileyo yokusikwa. Ukugcina isithunzi esigcweleyo kunokukhangeleka kwendalo kwimvelaphi efanayo kodwa kumdaka ngokuzaliswa okutsha okuqaqambileyo. Ukuyisusa kunokwenza umxholo ubonakale ngathi uyadada.

Ezi ziingxaki zokugweba njengeengxaki zemodeli.

Imaski yemodeli, imaski esebenzayo, kunye nemaski yokuthumela ngaphandle

Kuyanceda ukwahlula izigaba ezithathu:

1. Imaski yemodeli: uqikelelo oluzenzekelayo olubuyiswe ngentelekelelo.
2. Imaski esebenzayo: imaski eboniswe kumhleli emva kwayo nayiphi na into Yongeza okanye Cima ulungiso.
3. Thumela ngaphandle imaski: imaski esebenzayo isetyenziswa xa isiphumo sangoku sikhutshelwa okanye kukotshwa.

Kwi- Easy Background Remover, ucokiso lwebrashi luhlela imaski esebenzayo. Ukuthumela ngaphandle kusebenzisa isiphumo esihleliweyo sangoku kunokubuyela ngokuthe cwaka kwisigqubuthelo esizenzekelayo esingekachukunyiswa. Oku kuvumela imodeli iphathe ulwahlulo olubanzi ngelixa ulungisa iinkcukacha ezixhomekeke kwinjongo.

Imboniso ebonisiweyo inokukalwa ukuze ilingane nomhleli. Obo bukhulu bomboniso ayingomlinganiselo othembekileyo weenkcukacha zangaphakathi zemaski. Funda isisombululo semaski vs ubungakanani bemboniso ukuze ufumane umahluko.

Ingqikelelo yendawo isenenyathelo lokucwangcisa

Ukuqhuba imodeli kwisixhobo kufuna ubunzima bemodeli kunye nexesha lokusebenza lebrawuza elihambelanayo. Ubunzima bukhulu kakhulu kunekhowudi yojongano oluqhelekileyo, ke ukulayisha yonke into ekuqalisweni komhleli kuya kuba yinkcitho. Iseshoni yokuqala inokukhuphela kwaye igcine imodeli; iiseshini zamva nje eziqhelekileyo zinokuphinda zisetyenziswe kwakhona.

Kutheni khuphela imodeli kuqala ichaza loo mda ngaphandle kokubhidanisa ukhuphelo lwe-asethi yomfuziselo ngokulayisha ifoto. Ingqikelelo enzima nayo ibaleka kumsonto wojongano oluphambili; bona iziseko zokusetyenzwa komfanekiso woMsebenzi weWebhu.

Indlela esebenzayo yokugweba iziphumo

Musa ukuhlola umbindi wesifundo kuphela. Jonga imaski apho ubungqina bubuthathaka kakhulu:

• iinwele, uboya, amabhovu kunye nemicu yelaphu;
• iiglasi, imitya, iingcingo, kunye nezikhewu emxinwa;
• imida ephantsi yokuchasana;
• imathiriyeli engafihliyo;
• izithunzi zoqhagamshelwano;
• iikona apho umbala ongasemva omdala unokuhlala khona.

Jonga isiphumo phezu kokubini ukukhanya kunye nemvelaphi emnyama ukuba indawo yokugqibela ayaziwa. I-halo ephaphathekileyo inokunyamalala kumhlophe kwaye ibonakale kumnyama. Emva koko coca kuphela iindawo ezichaphazela ukusetyenziswa okucetywayo.

Ukwahlulahlula okuzenzekelayo kuluncedo kakhulu xa iphathwa njengepasi lokuqala eliqinileyo, hayi ingxelo yokuqonda okugqibeleleyo. Ukuzama ukusika okupheleleyo kwasekuhlaleni kunye nophuculo olupheleleyo, bona Qalisa.
