Indlela yokufaka i-JPEG esuka ngasemva

1 Layisha phezulu i JPEG images ofuna ukuyicima - into ecacileyo echaphazela isiqalo esichaphazelayo inika imodeli into encinci yokucinga.

2 Lumka ngelixa imodeli yokwahlula-hlula ilindele i-alpha matte ye-pixel nganye; akukho khuselo lokwenza ngesandla.

3 Khangela imiphetho kwimboniso, ngakumbi iinwele, iinwele zekati, iglasi kunye nokungaboni kakuhle kwendlela, apho nayiphi na i-matte ekhawulezayo ifuna khona.

4 Layisha ezantsi iziphumo njenge-PNG okanye i-WebP ukuze ukubonakala kuhlale kuqhubeka — ukugcina ukutywina njenge-JPG kubeka umthunzi umva.

Susa Isiqalo se-JPEG FAQ

Ichanekile kangakanani i-cut-out kwimiphetho enzima?

Izinto eziqinileyo ezichaphazela umva ophawulekayo ziphuma zihle. Iinwele ezilungileyo, iinwele, ukubonakala okungabonakaliyo, iglasi kunye nekhonkco lekhonkco lekhonkco zilapho naziphi na iinwele ezizenzekelayo zixhaphaza khona, kwaye apho ungathanda ukuphinda usebenzise impumelelo ngesandla emva koko.

Ifomati yendlela yokusebenza ifanele igcinwe ngayo?

Enye enesiqhagamshelanisi se-alpha senyaniso - PNG okanye WebP. Ukugcina ukutywina njenge-JPG kususa ukubonakala kwaye kudibanisa okubhaliweyo kumnyama, oku kuphulukana nomsebenzi wonke kwaye kuyindlela eqhelekileyo eqhelekileyo ehamba kakubi apha.

Ndingayiqhubekekisa iqela elipheleleyo lemifanekiso?

Ewe. Umfanekiso ngamnye uhlukaniswe ngokweziqu, ngoko iqela lemveliso ejikelezayo liyakwazi ukutywinwa kwindlela enye - eqhelekileyo injongo, ukusukela ukuba yenza ngesandla inxalenye ekhawulezayo yencwadi yemifanekiso ejikelezayo.

I Susa Isiqalo se-JPEG igqiba njani ukuba yintoni engaphambili?

Ngokucacileyo, a U^2- Net segmentation model predicts a per- pixel alpha matte and the background is cut away - but a lossy source has soft, compressed edges, so the matte is refined afterwards, and the output has to go to a format with an alpha channel rather than back to a lossy one. Akukho inyathelo lokufihla elibhalwe ngesandla - imodeli yokwahlula-hlula i-neural isenza uhlukaniso kwaye ufumana i-result ecacileyo ebuyela umva.

Ndingaqhuba i Susa Isiqalo se-JPEG kwi JPEG images ezininzi ngaxeshanye?

Ewe. Nciphisa iqela lonke kwindawo yolayisho phezulu kwaye ziphole ngokuthe ngqo ngemimiselo efana nayo - le yisizathu esiphambili sokwenza oku kumkhangeli zincwadi kunokuba yifayile enye ngexesha kumhleli. Iiakhawunti ezikhululekileyo ziqhuba ifayile enye kwiqela; i pass iphakamisa loo nto.

Ingaba i Susa Isiqalo se-JPEG ibiza nantoni na?

Umhlathi Susa Isiqalo se-JPEG ukhululekile ngaphandle kwe-akhawunti, akukho phawu lwamanzi kwimveliso kwaye akukho mnatha wobhaliso phambi kokukhuphela. Ukukhuphela kususwa ngokuzenzekelayo ngexesha elifutshane emva kokuba umsebenzi ugqibile.

Yintoni endinokuyilayisha kwi Susa Isiqalo se-JPEG?

Nantoni na ekufumaneni usapho lwe-raster - JPG, JPEG, JFIF ne-WebP - kunye neefomati ezingalunganga (PNG, BMP, TIFF) ukuba ufuna ukuzidibanisa kwiqela elinye. Ifomati ifundwa kwisihloko sefayili, hayi kwisiphelo, ngoko ke umfanekiso ogciniweyo nge-suffix engafanelekanga uhlala udlula.

Ingaba i Susa Isiqalo se-JPEG iya kunyusa ubunjani be JPEG images yam?

Umthombo olahlwayo sele uyimpumelelo yendlela enye yokugqitha, kwaye nayiphi na imisebenzi efuna ukubuyisela ikhowudi idibanisa enye. Xa umsebenzi ungakwenziwa ngaphandle kokucofa i-pixel data siyenza endaweni, kwaye apho ayikwazi khona ukhetha umgangatho wezinto eziluncedo ngokwakho kunokuba ufumana okumiselweyo okumiselweyo.

Ingaba i Susa Isiqalo se-JPEG ibekwe kwindawo ethetha ngefomati yefoto?

JPEG.to ibekwe phantsi kwefomati ehambisa imifanekiso eninzi ekhoyo - iminyaka emashumi mathathu ebudala, ivuliwe ngokucacileyo ngazo zonke izinto, kwaye ihlala ilungile ekumiselweni kwemifanekiso ebonakalayo. Imisebenzi abantu bazisa apha yiyo efoto iqoqa ubomi bayo - enkulu kakhulu ukuba i-imeyile, iimfuno ezingachanekanga zefomu, indlela engachanekanga ukuya phezulu ngaphandle kwefowuni. Susa Isiqalo se-JPEG iqhuba kwi-upload efanayo kunye ne-akhawunti efanayo njenge-conversions kuba apho apho imisebenzi iwela khona.

Yintoni inyathelo elilandelayo elifanelekileyo emva kwe Susa Isiqalo se-JPEG?

Umguquli kule ndawo uhambisa imifanekiso ukuya nakwi-JPEG, PNG, WebP ne HEIC, apho urhwebo phakathi kobungakanani befayili kunye nohlobo oluthile lokuphelelwa lihlala khona. Ukugqiba ifomati yokugqibela kunokuba yokuqala yindawo epheleleyo: yonke i-extra igcina umfanekiso womfanekiso ufana nolunye udidi, kwaye uchitha ngaphantsi, uninzi lomfanekiso uhlala.

Ingaba le yinjini efanayo nezinye iindawo zokuguqula?

Ewe - iilayibrari ezifanayo, abasebenzi abafanayo, iziqhoboshi ezifanayo. Utshintsho luyinto ecebisayo kwiphepha, kwaye apha loo cebiso lidityaniswe kwipropathi enye yefomati indawo ibizwa emva: i.jpeg ne.jpg izilungiso ziyi-bitstream efanayo, ngoko akukho nto apha esebenza ngokuhlukileyo kune-.jpg — kuphela igama lefayili litshintsha.

Ingaba kukho into egcinwe, kwaye ngaba ndifuna ukungena?

Akukho nto igcinwa kwaye akukho akhawunti ifunekayo. Ulayisho lususwa abasebenzisi emva komsebenzi ugqibile; akukho nto ijongwe, idweliswe okanye iqulathe isalathisi. I akhawunti ithenga imbali kunye neentlanganiso ezinkulu, hayi unikezelo.
