Izisekelo zokucubungula izithombe zeWebhu

By Technical specialist

Isisebenzi Sewebhu siwumongo ohlukile wokusebenzisa we-JavaScript ongenza izibalo ezibizayo ngaphandle kokwenza uchungechunge oluyinhloko lomhleli lwenza wonke umsebenzi. Ngokucutshungulwa kwesithombe sesiphequluli, lokho kusho ukuthi ukusethwa kwemodeli nokuchazwa kungabaleka kuchungechunge olunesibopho sezinkinobho, imilayezo yokuqhubeka, okokufaka kwebhulashi, nezibuyekezo zesikrini.

Umphumela awukona “ukucutshungulwa kwangemuva kwamahhala.” Idivayisi efanayo isabala futhi isebenzisa inkumbulo. Inzuzo yezakhiwo ukuhlukaniswa: ukusebenza kwemodeli esindayo mancane amathuba okuthi kuvinjwe yonke impendulo yesixhumi esibonakalayo ngenkathi isebenza.

Uchungechunge oluyinhloko lunomsebenzi wesixhumi esibonakalayo somsebenzisi

Ikhasi lesiphequluli livamise ukusebenzisa i-JavaScript kuchungechunge oluyinhloko. Leyo ntambo iphinde ixhumanise ukwakheka, ukudweba, nokokufaka. Uma kubalwa okude okukodwa, ukuchofoza kungase kuzwakale kubambezelekile, ukugqwayiza kungama, futhi isiphequluli singase sixwayise ngokuthi ikhasi aliphenduli.

Umhleli wesithombe unezibopho eziningi zochungechunge oluyinhloko ngaphambi kokuthi kuqale nokuqala:

• thola ukukhethwa kwefayela, unamathisele, noma udedele;
• qopha futhi ubonise isithombe;
• buyekeza inqubekelaphambili kanye nezimo zamaphutha;
• dweba i-canvas yokubuka kuqala;
• bamba Engeza futhi Sula ukunyakaza kwebhulashi;
• lungiselela ukulanda noma izenzo zebhodi lokunamathisela.

Ukubeka umsebenzi wezinombolo wemodeli yokuhlukanisa kuchungechunge olufanayo kungenza leyo misebenzi iqhudelane ngokuqondile. Isisebenzi sakha umngcele ocacile.

Umngcele osuselwe emlayezo

Umhleli nesisebenzi abahlanganyeli ngokuguquguqukayo okujwayelekile. Baxhumana ngokuthumela imiyalezo. Ukugeleza okwenziwe lula kubukeka kanje:

1. Umhleli udala noma uphinde asebenzise isisebenzi.
2. Icela isisebenzi ukuthi siqalise isikhathi sokusebenza sokuqagela kanye nemodeli.
3. Ilungiselela idatha yesithombe futhi ithumele isicelo sokucatshangelwa.
4. Isisebenzi siguqula idatha ibe okokufaka okulindelekile kwemodeli.
5. Isisebenzi siqhuba imodeli futhi sikhiqize amanani e-mask.
6. Ithumela imaski noma idatha yomphumela emuva.
7. Umhleli uhlanganisa ukubuka kuqala futhi anike amandla ukucolisiswa noma ukuthekelisa.

Imilayezo kufanele ifake umongo owanele ukufanisa impendulo nesicelo esifanele. Lokhu kubalulekile uma umsebenzisi ekhetha esinye isithombe ngaphambi kokuthi umsebenzi wangaphambilini uphele. Isixhumi esibonakalayo kufanele sigweme ukubonisa umphumela omdala phezu komthombo omusha.

Ikopisha futhi idlulise idatha yesithombe

Ukuthumela umlayezo wombhalo omncane kushibhile. Ukuthumela izigidi zamavelu e-pixel kungabiza uma isiphequluli kufanele sikopishe yonke ibhafa. Ama-Web API angadlulisela ubunikazi bamabhafa athile kanambambili esikhundleni salokho. Ibhafa edlulisiwe itholakala kumamukeli ngaphandle kokugcina impinda esebenzisekayo ohlangothini lomthumeli.

Lokho kulungiselelwa kuza nesithiyo sedizayini: ngemva kokudlulisa, umthumeli akakwazi ukuqhubeka esebenzisa isigcinalwazi esifanayo njengokungathi kusengumnikazi wedatha. Umhleli angase agcine isethulo esihlukile sokuboniswa, adale isigcinalwazi esizinikele, noma akhe kabusha lokho akudingayo kamuva.

Akuwona wonke ukuqaliswa okusebenzisa ukudlulisa ezindaweni ezifanayo ncamashi. Isifundo esijwayelekile ukuthi ukuhlukaniswa kwentambo akukwenzi ukunyakaza kwedatha kunyamalale. Ubukhulu besithombe, usayizi webhafa, kanye nenani lokuguqulwa kusathinta ukubambezeleka nenkumbulo.

Yini Easy Background Remover efaka isisebenzi

Easy Background Remover isebenzisa Isisebenzi Sewebhu esine-inference yesiphequluli sesikhathi sokusebenza sokuhlukaniswa kwedivayisi. Isinyathelo esisindayo sokusika esizenzakalelayo sikhiqiza imaski. Umhleli ube esebonisa umphumela ohlanganisiwe futhi asekele ukucoliswa kwebhulashi lekhanvasi ye-CPU.

Lokhu kuhlukaniswa kunikeza ukuhluleka umngcele owusizo kakhulu. Uma isisebenzi singakwazi ukuqalisa noma siphahlazeke ngesikhathi sokucatshangelwa, isixhumi esibonakalayo singabika iphutha elihlobene nomsebenzi esikhundleni sokuthembela kuthebhu efriziwe unomphela njengesignali kuphela.

Iphinde igcine isimangalo sokucubungula indawo siqondakala. Ukuthumela amaphikseli kusuka ekhasini lesandiso ukuya kusisebenzi saso ukuxhumana ngaphakathi kwendawo yesiphequluli, hhayi ukulayisha ku-API yokusika eyirimothi. Iseshini yokuqala ingadawuniloda ngokuhlukana ifa eliyimodeli elisebenziseka kabusha; bona Kungani uqale ulande imodeli.

Isisebenzi asikwenzi ukubala ngokushesha

Izisebenzi zithuthukisa ukusabela, hhayi amandla edivayisi eluhlaza. Imodeli isasebenzisa i-CPU, i-GPU, noma ezinye izinsiza zesikhathi sokusebenza ngokuya ngalokho isiphequluli esingakunikeza. Okokufaka okukhulu kusengathatha isikhathi eside futhi kudinga inkumbulo eningi kunencane.

Kusele imikhawulo eminingana:

• ukuqaliswa kwemodeli kunezindleko zangempela;
• Ama-pixel buffers athatha inkumbulo nhlangothi zombili uma ekopishiwe;
• ukushintsha usayizi kanye nokuguqulwa kwefomethi kuthatha isikhathi;
• Amadivayisi anenkumbulo ephansi angase alwe nezithombe ezinkulu;
• abasebenzi abaningi bangandisa umbango esikhundleni sokuwunciphisa;
• ukuthekelisa kanye nezibuyekezo zekhanvasi zisengabandakanya uchungechunge oluyinhloko.

Ukuqala izisebenzi ezinhlanu zokukhomba izithombe ezinhlanu akusheshi ngokuzenzakalelayo ngokuphindwe kahlanu. Abasebenzi babelana ngomshini ofanayo. Imisebenzi efanayo ingaqhudelana ngomkhawulokudonsa wememori nezisetshenziswa zokwenza, kuyilapho imodeli ngayinye ingase ithwale izindleko zayo zememori.

Ukubika ngenqubekelaphambili kuyasebenzisana

Isisebenzi singathumela imilayezo yesimo, kodwa asazi ngokuzenzakalelayo ukuthi yimaphi amaphesenti enqubekelaphambili azozwakala anembe. Ukulanda imodeli, ukuqalisa kwesikhathi sokusebenza, ukulungiselela okokufaka, okucatshangelwayo, ukuguqulwa kwemaski, nokunikezwa kokubuka kuqala kuyizigaba ezihlukene ezinesikhathi esihlukile.

Ezinye izigaba zinezibalo zebhayithi ezilinganisekayo. Ukwenziwa kwemodeli eyodwa kungadalula kuphela okuthi “kuqaliwe” nokuthi “kuqediwe.” Ngakho-ke amaphesenti abushelelezi athuthuka ngokufana angaba yizimonyo kunokuba abe nesilinganiso esinembile.

I-UI yenqubekela phambili ewusizo ibiza isigaba uma kungenzeka: ukulungisa imodeli, ukucubungula isithombe, noma umphumela wokwakha. Iphinde isingathe ukwehluleka nokukhansela esikhundleni sokushiya isipina ngaphandle kwencazelo.

Ukukhansela kungaphezu kokufihla isipina

Uma umsebenzisi evala isithombe noma eqala kabusha, isixhumi esibonakalayo singaziba impendulo evela esicelweni esiphelelwe yisikhathi. Ukumisa ukubala okuyisisekelo ngokushesha kungase kudinge ukwesekwa okwengeziwe kusukela ngesikhathi sokusebenza noma ukunqamula kanye nokudala kabusha isisebenzi.

Ukunqamula isisebenzi kuyisinqumo, kodwa kulahla isimo saso sokuqala. Umsebenzi olandelayo ungase udinge ukulayisha futhi uqalise imodeli futhi. Ngokuhlinzwa okufushane, ukumaka umphumela umdala kungase kushibhe kunokubhidliza yonke into.

Ukukhetha okulungile kuncike ekucindezelweni kwenkumbulo, ubude besikhathi sokusebenza, namandla wesikhathi sokusebenza. Ngokombono womsebenzisi, umthetho obalulekile ukuthi umsebenzi omdala akumele ubhale ngaphezulu ukuhlela kwamanje.

Amaphutha adinga ukweqa umngcele nawo

Okuhlukile ngaphakathi kwesisebenzi akubi okwehlukile komucu oyinhloko. Umsebenzi kufanele abike amaphutha asebenzisekayo, futhi umhleli kufanele alalele ukwehluleka kwezinga lomsebenzi.

Ukuphatha amaphutha okuhle kuhlukanisa okungenani:

• imodeli yempahla ayitholakali;
• ukuqaliswa kwemodeli kwehlulekile;
• I-decode yesithombe noma ukulungiswa kokufaka kwehlulekile;
• ukubikezela kuhlulekile;
• isisebenzi sime ngokungalindelekile;
• umphumela awusewona owesicelo samanje.

Lokhu kuyasebenza kakhulu kunokuthi “okuthile akuhambanga kahle,” ikakhulukazi uma ukusetha kokuqala nokucutshungulwa kwesithombe okujwayelekile kunezixazululo ezihlukile.

Okuphumayo kwesisebenzi kuseyimaski yokuqala kuphela

Isakhiwo sochungechunge asithuthukisi umphetho ongacacile ngokwawo. Isisebenzi singabuyisela imaski evumelekile ngokobuchwepheshe esaphuthelwa uboya, izinto ezibonisa ngale, izintambo eziwumngcingo, noma isithunzi esifunwayo. Leyo yimibuzo yokuhlukanisa kanye nenhloso.

Umsebenzi womhleli uyaqala futhi ngemva kokucabangela: sika imaski ohlelweni lokudidiyela olusebenzayo, hlanganisa ukubuka kuqala, vumela umsebenzisi ukuthi asilungise, futhi uthumele isimo samanje. Ukulungiswa kwemaski kuqhathaniswa nosayizi wokubuka kuqala kuchaza ukuthi kungani lawo masistimu wokuxhumanisa kungafanele adideke.

Imodeli yengqondo emfushane

Cabanga ngesisebenzi njengochwepheshe bendawo ngemuva kwewindi lomlayezo:

• umhleli ungumnikazi wokusebenzisana;
• isisebenzi siphethe umsebenzi onzima wokukhomba;
• idatha yesithombe kanambambili yeqa umngcele ochaziwe;
• isisebenzi sibuyisela isifihla-buso, hhayi ukwahlulela okuphelile kuwo wonke umkhawulo;
• umhleli uhlala enomthwalo wemfanelo ngesimo samanje, ukubuyekezwa, ukucwengwa, kanye nokuthekelisa.

Ukuze uthole umbono wemodeli wamaphikseli ngokwawo, qhubeka ngokuthi Lokho okubonwa imodeli yokusika ekudivayisi. Ukuze uthole ukubuka konke okusebenzayo, bona Indlela ukususa ingemuva lendawo okusebenza ngayo.
