Yeka ukuthi imodeli yokusika ekudivayisi ibonwa kanjani

By Technical specialist

Imodeli yokusika ekudivayisi ayiboni umuntu, isicathulo, isilwane esifuywayo, noma isitulo ngomqondo womuntu. Ithola ukumelwa kwezinombolo kwesithombe nezilinganiso, iphikseli ngephikseli, okuyizindawo okungenzeka zibe ezesihloko esikhulu. Okukhiphayo okuwusizo kuyimaski: imephu empunga engaba umzila osobala womphumela.

Lowo mehluko uchaza kokubili isivinini sokusika okuzenzakalelayo kanye nemikhawulo yakhona. Imodeli ingasebenzisa amaphethini abonwayo afundwe ngesikhathi sokuqeqeshwa, kodwa ayazi inhloso yakho. Into ecijile eduze nendawo ingase ibukeke ibalulekile; i-rim yengilazi epholile noma umucu wezinwele oxekethile ungase ubukeke njengengemuva.

Ukusuka kufayela lesithombe kuye kokufakwayo okuyimodeli

Ifayela olikhethayo kuqala kufanele liqoshwe. Isithombe esicindezelwe asidluliswa ngokuqondile kumodeli njengebhulokhi lamabhayithi wefayela. Isiphequluli siyiguqula ibe amaphikseli anobubanzi, ubude, namanani ombala.

Ipayipi lokukhomba libe selilungiselela okokufaka kosayizi wemodeli. Ngokuya ngemodeli nesikhathi sokusebenza, ukulungiselela kungabandakanya:

• ukushintsha usayizi wesithombe esihlukanisiwe sibe ubukhulu obulindelwe yimodeli;
• ukuhlela amanani abomvu, aluhlaza, naluhlaza njengeziteshi zezinombolo;
• ukukala noma ukwenza lawo manani ajwayelekile;
• ukuwapakisha ku-tensor, ifomethi yamalungu afanayo esetshenziswa isikhathi sokusebenza sokuqagela.

Ubukhulu obuqondile nemithetho yokujwayela ingeyokusetshenziswa kwemodeli. Iphuzu eliwusizo elibalulekile ukuthi ukucatshangelwa kuvame ukusebenza kusukela kumfanekiso olungiselelwe, hhayi kuwo wonke amaphikseli omthombo ngosayizi wawo wangempela.

Easy Background Remover isebenzisa lesi sinyathelo sokunquma esipheqululini ngemodeli yokuhlukanisa ekudivayisi. Ifayela eliyimodeli lingase lidinge ukulandwa ngaphambi kokusikwa kokuqala, kodwa indlela yokucubungula isithombe iklanyelwe ukuhlala isendaweni uma imodeli isilungile. Ukulandwa kwemodeli kuyisicelo sempahla; akuyona into efanayo nokulayisha isithombe esikhethiwe ukuze uthole ukwaziswa okukude.

Okukhiphayo kuyimaski efana nokuzethemba

Kundawo ngayinye ekukhiqizweni kwayo, imodeli ikhiqiza inani elingahunyushwa njengelifana nesihloko noma elifana nengemuva. Kuyasiza ukuthwebula lokhu njengesithombe esimpunga:

• izindlela ezimhlophe gcina le ndawo;
• izindlela ezimnyama susa le ndawo;
• okumpunga kusho ukumbozwa kancane noma ukungaqiniseki eduze komphetho.

Isiphequluli siguqula lokho okukhiphayo kube imaski ye-alpha esebenzayo. Amaphikseli ombala wangempela angase ahlanganiswe phezu kwebhodi lokuhlola, ukugcwaliswa okuqinile, i-gradient, noma esinye isithombe. Ukuthekelisa okubonakalayo kugcina imaski njenge-alpha kunokupenda ibhodi lokuhlola efayeleni.

Amanani athambile anendaba. Uma lonke inani lemaski liphoqeleka ngokushesha ukuthi libe mnyama noma kumhlophe qwa, izinwele, uboya, imicu yendwangu, ukufiphala kokunyakaza, nemiphetho engagxilile bekuzoba nzima ngendlela engavamile. I-alpha eyingxenye ingagcina inguquko ebushelelezi. Ingase futhi iveze umphetho wombala ovela kungemuva elidala, yingakho umphumela usafanele ukuhlolwa okubonakalayo.

Yibuphi ubufakazi obubonakalayo obusiza imodeli

Imodeli yokuhlukanisa ingadonsa kumkhondo ongaphezu kowodwa ngesikhathi esisodwa. Izimpawu eziqinile ngokuvamile zihlanganisa:

• umehluko phakathi kwesihloko nesizinda;
• imingcele eqhubekayo ezungeze into evelele;
• inhlanganisela ejwayelekile yomumo, ukuthungwa, nendawo;
• izimpawu zokujula njengomehluko wokugxila;
• izifunda ezibukeka zihlangene.

Ayikho kulezi zinkomba eziyisiqinisekiso. Ijazi elimnyama elibhekene nodonga olumnyama linikeza ukungafani okubuthakathaka komngcele. Isihlalo esinezikhala ezincane singaqukatha izifunda ezingemuva ezifana nento. Ingemuva elinephethini lingaqhudelana nesihloko sangempela ukuze sinakwe.

Imodeli yenza isilinganiso esihle kakhulu ngamaphikseli atholakalayo. Ayikwazi ukubuyisela imininingwane engakaze ithathwe isithombe.

Ukuthi imodeli ayikwazi

Imodeli ayazi ngokuzenzakalelayo ukuthi iyiphi into obufuna ukuyigcina uma kukhona izifundo ezimbalwa. Akwazi ukuthi ingilazi yokuphuza esobala ibalulekile kwezohwebo, ukuthi isithunzi kufanele sihlale ukuze sibhekane namaqiniso, noma ukuthi ibhande elincane lingelesikhwama.

Futhi ayitholi inguqulo efihliwe yokulungiswa okuphezulu yomthombo ofiphele. Amabhulokhi okucindezelayo, amaphuzu avelele aqoshiwe, ukufiphala kokunyakaza, kanye nemininingwane emincane kakhulu ikhawulela ubufakazi obutholakalayo. Ukwandisa ukusondeza kokubuka kuqala kwenza amaphikseli abe makhudlwana esikrinini; ayidali ulwazi olungekho.

Yingakho “i-AI ihlonze” futhi “umphetho usulungele ukushicilelwa” izimangalo ezihlukile. Ukutholwa kuqala ukuhlela. Ukubuyekeza kuyaqeda.

Kungani imininingwane emincane nesobala inzima

Izinto ezizacile zithatha amaphikseli ambalwa. Uma isithombe sishintshwa usayizi ukuze kube okucatshangelwayo, intambo eyiphikiseli eyodwa noma umucu wezinwele ungase ulinganiselwe nengemuva elisizungezile. Izinto ezisobala zinzima ngesinye isizathu: umbala wazo obonakalayo ngokwengxenye ingemuva elidala. Umngcele ungase ucace kumuntu oyiqondayo into, kuyilapho iphethini yephikseli ihlala ingaqondakali.

Izithunzi ezithambile zidala ukungaqondakali okuhlosiwe. Unqenqema lwazo lwangaphandle luyanyamalala kancane kancane, futhi akukho ukusika okukodwa okulungile. Ukugcina isithunzi esigcwele kungase kubukeke kungokwemvelo kungemuva elifanayo kodwa kungcolile ekugcwalisweni okusha okukhanyayo. Ukuyisusa kungase kwenze isihloko sibonakale sintanta.

Lezi yizinkinga zokwahlulela njengezinkinga zemodeli.

Imaski eyimodeli, imaski yokusebenza, kanye nemaski yokuthekelisa

Kuyasiza ukuhlukanisa izigaba ezintathu:

1. Imaski yemodeli: isilinganiso esizenzakalelayo sibuyiswe ngokuqonda.
2. Imaski esebenzayo: imaskhi eboniswe kumhleli ngemva kwanoma yikuphi ukucwengwa kwe-Engeza noma Susa.
3. Thumela imaski: imaski esebenzayo isetshenziswa lapho umphumela wamanje ulandwa noma ukopishwa.

Ku-Easy Background Remover, ukulungiswa kwebhulashi kuhlela imaski esebenzayo. Ukuthekelisa kusebenzisa umphumela wamanje ohleliwe kunokubuyela buthule kumaski ozenzakalelayo ongakathintwa. Lokhu kuvumela imodeli ukuthi isingathe ukuhlukaniswa okubanzi ngenkathi ulungisa imininingwane encike kunhloso.

Ukubuka kuqala okubonisiwe kungase kukalwe ukuze kulingane nesihleli. Lowo sayizi wokuboniswa awusona isilinganiso esithembekile semininingwane yangaphakathi yemaski. Funda Ukulungiswa kwemaski kuqhathaniswa nosayizi wokubuka kuqala ukuze uthole umehluko.

Incazelo yendawo isenesinyathelo sokusetha

Ukuqalisa imodeli kudivayisi kudinga izisindo zemodeli kanye nesikhathi sokusebenza sesiphequluli esihambisanayo. Izisindo zikhulu kakhulu kunekhodi yesixhumi esibonakalayo esijwayelekile, ngakho ukulayisha yonke into kukho konke ukwethulwa komhleli kungaba ukumosha. Iseshini yokuqala ingadawuniloda futhi igcine imodeli; amaseshini akamuva ajwayelekile angaphinda ayisebenzise.

Kungani uqalise ngokulanda imodeli ichaza lowo mngcele ngaphandle kokudida ukulandwa kwefa kwemodeli ngokulayisha isithombe. Ukucabanga okusindayo nakho kubalekela intambo yesixhumi esibonakalayo; bona Izisekelo zokucubungula izithombe ze-Web Worker.

Indlela engokoqobo yokwahlulela umphumela

Ungahloli kuphela isikhungo sesihloko. Hlola imaski lapho ubufakazi bubuthakathaka khona:

• izinwele, uboya, amadevu, nemicu yendwangu;
• izibuko, izintambo, izintambo, nezikhala ezincane;
• imiphetho ephansi yokuqhathanisa;
• impahla esobala kancane;
• izithunzi zokuxhumana;
• amakhona lapho umbala wangemuva omdala ungase uhlale khona.

Buka umphumela phezu kokubili kwengemuva elikhanyayo nelimnyama uma indawo yokugcina ingaziwa. I-halo ephaphathekile inganyamalala kokumhlophe futhi ibonakale kumnyama. Bese uhlunga kuphela izindawo ezithinta ukusetshenziswa okuhlosiwe.

Ukuhlukaniswa okuzenzakalelayo kusiza kakhulu uma kuphathwa njengokudlula okuqinile kokuqala, hhayi isitatimende sokuqonda okuphelele. Ukuze uzame ukusika okuphelele kwasendaweni nokugeleza kokuthuthukisa, bona okuthi Qalisa.
