Mask gukemura vs ingano yo kureba

By Technical specialist

Gukemura mask hamwe nubunini bwo kureba bifitanye isano, ariko ntabwo bipima kimwe. Icyemezo cya mask gisobanura pigiseli ya gride ibika gukwirakwiza ibintu. Ingano yimbere isobanura uburyo bunini umwanditsi ashushanya ibisubizo kuri ecran yawe. 300-pigiseli-ubugari irashobora kwerekana ishusho nini cyane; guhinduranya ibyo kureba ntabwo byongera mask nshya.

Kwitiranya byombi birashobora kuganisha ku myanzuro itari yo. Igice gishobora kugaragara neza mugihe gishyizwe kumwanya muto hanyuma kigaragaza halo mubunini bwohereza hanze. Irashobora kandi kugaragara neza kuri zoom ikabije nubwo izo pigiseli ya mask ya buri muntu itagaragara mugukoresha bisanzwe.

Ingano eshatu zirashobora kubaho muguhindura kimwe

Mucukumbuzi ikata akazi irashobora kuba irimo byibuze imyanya itatu ihuza:

1. ** Ingano yinkomoko: ** ubugari bwa decode nuburebure bwishusho yahisemo.
2. ** Umwanzuro cyangwa ingano ya mask ikora: ** gride ibarwa ikwirakwizwa kandi ikosorwa.
3. ** Ibipimo byerekana mbere: ** ibipimo byerekana bihuye n’ahantu haboneka umwanditsi.

Ingano irashobora guhura, ariko ntabwo igomba. Inkomoko nini irashobora kugabanuka imbere kubwicyitegererezo cyo kugenzura igihe cyo kwibuka. Mask yavuyemo irashobora noneho gupimwa mumurimo wo gukora cyangwa kohereza hanze. Hanyuma, mushakisha yongeye gupima ibice kugirango ihuze na ecran.

Easy Background Remover irashobora gutunganya amashusho manini cyane mugukemura imbere imbere no kwerekana umuburo. Kwohereza hanze biracyareba ibipimo byinkomoko. Ibi bituma ibipimo bisohoka bifite akamaro, ariko ntibishobora guhimba amakuru arambuye yabuze muri mask yabazwe imbere.

Niki mask ya pigiseli ibika

Mask ntabwo byanze bikunze umukara-cyangwa-umweru. Buri masikeli pigiseli irashobora gufata alfa agaciro uhereye inyuma ukoresheje igice kugeza kubintu byose byagumishijwe.

Ku kintu gikomeye, inzibacyuho irashobora gufata gusa umurongo muto. Ku musatsi woroshye, ubwoya, ubururu, cyangwa igicucu, ingirakamaro zingirakamaro zishobora kuzenguruka ahantu hanini. Iyo mask ihinduwe, interpolation igereranya agaciro hagati yicyitegererezo cyambere.

Interpolation irashobora gukora inzibacyuho muburyo bworoshye. Ntishobora kugarura imiterere nyayo yumurongo wabuze mugihe cyo gukemura bike. Koroha no kugarura amakuru ni imico itandukanye.

Impamvu ibiteganijwe bikwiye bihisha inenge

Iyo umwanditsi ahuje ishusho nini mumwanya muto, pigiseli nyinshi yinkomoko igira uruhare kuri buri pigiseli yerekanwe. Utwobo duto, impande imwe ya pigiseli, na alfa itaringaniye irashobora kugereranywa kure.

Ibyo ni ingirakamaro mu guhimba: urashobora kumenya niba ingingo yibanze kandi niba gutandukana kwagutse ari byo. Ntabwo bihagije kubwiza bwiza.

Isubiramo ryizewe rikoresha igipimo kirenze kimwe:

• kureba neza ingingo yose;
• kuringaniza mu buryo bushyize mu gaciro no gutandukanya imbere;
• zoom zo hejuru gusa ahantu hakekwa;
• igenewe-gukoresha ingano y’urubanza rwa nyuma.

Niba ishusho izahinduka avatar ntoya, inenge ya microscopique ntishobora na rimwe kugira icyo itwara. Niba izacapurwa nini cyangwa igashyirwa hejuru yijimye, inenge imwe irashobora kugaragara.

Kuki zoom ishobora gutuma impande nziza zisa nabi

Kuri zoom zo hejuru, umwanditsi yagura pigiseli yihariye. Intambwe zintambwe ziteganijwe kumupaka wa diagonal kandi uhetamye kuko pigiseli ya gride ntabwo ikomeza. Inzibacyuho yoroshye irashobora kandi kumera nkimyenda igaragara iyo buri pigiseli yagutse.

Ikibazo ntabwo ari ukumenya niba pigiseli igaragara kuri 800 ku ijana. Bazobikora. Ibibazo byingirakamaro ni:

• Imipaka iri ahantu heza?
• Ese impande zisa nkibisanzwe byerekana ubunini bwerekanwe?
• Haba hari ibara rya kera ryibara rivanze muri pigiseli igice?
• Ese amakuru yingenzi aragumanye?
• Ese inzibacyuho ya alfa ihuye nisomo?

Ntugahanagure pigiseli yoroshye yemewe gusa kuberako isa nicyatsi kibaho kugenzura kuri zoom ikabije. Banza ugerageze hejuru yukuri yerekanwe.

Ibipimo byinkomoko ntabwo byemeza inkomoko-urwego rurambuye

PNG yoherejwe hanze irashobora kugira ubugari n’uburebure nkisoko mugihe mask ya alfa yatangiriye kumurongo wo hasi. Kuzamura amakarita yerekana masike yuzuye-pigiseli y’amabara. Ibipimo bya dosiye bikomeza kuba ukuri, ariko imbibi zuzuye zigarukira kumakuru yo muri mask yo hasi-yo gukemura no gutunganywa nyuma.

Ibi bisa no gushushanya urucacagu rworoshye kurupapuro rwerekana kandi ukarwagura. Urupapuro rwagutse rushobora koroshya, ariko ntirubona imigozi itigeze ishushanywa.

Ibyo ntibituma kugabanya umwanzuro bidafite akamaro. Amasomo menshi afite impande zisobanutse, zagutse, nubunini bwimbere bushobora gutanga uburinganire bwiza hagati yumuvuduko, gukoresha kwibuka, hamwe nubwiza. Bisobanura ko utuntu duto dukwiye kwitabwaho bidasanzwe.

Brushes ikenera guhuza amakarita

Iyo ushushanyije Ongeraho cyangwa Gusiba inkoni ku bipimo byapimwe, umwanditsi agomba gushushanya ikarita yerekana guhuza ibikorwa bya mask. Radiyo ya brush nayo ikeneye ibisobanuro bihamye. Uruziga rwa pigiseli icumi kuri ecran ntigomba guhinduka kubwimpinduka zinyuranye rwose kuberako ibyerekanwe byahinduwe.

Konti nziza yo gushushanya kuri:

• igipimo cyo kureba mbere na offset;
• guhinduranya ikintu icyo ari cyo cyose;
• inkomoko-kuri-mask igipimo;
• igipimo cya pigiseli igikoresho;
• koza radiyo n’ubwitonzi.

Itandukaniro rito ryo kuzenguruka ntirishobora kwirindwa, ariko inshuro nyinshi zigomba kugwa aho icyerekezo cyerekana. Niba ubwonko bugaragara, banza urebe niba canvas yarateguwe cyangwa niba amashanyarazi ya zoom yahinduye imiterere mbere yo gutekereza ko mask yerekana nabi.

Umucyo n’umwijima byerekana pigiseli zitandukanye

Ikibaho cyerekana itumanaho, ariko ntabwo ari ikizamini cyiza kuri bose. Ibisigara byera bivuye inyuma yera birashobora kuvanga mumirongo yoroheje. Impande zijimye zirashobora kuzimira kuruhande rwijimye.

Subiramo impande imwe hejuru:

• cyera cyangwa irindi bara ryoroshye;
• umukara cyangwa irindi bara ryijimye;
• ibara hafi yicyerekezo;
• gukorera mu mucyo niba ibyoherezwa hanze bisaba alfa.

Impande ikora kumurongo uko ari itatu irakomeye. Niba ibisohoka byanyuma buri gihe bikoresha icyuzuzo gihamye, hindura aho ujya aho guhiga gutunganirwa neza ahantu hose.

Masike, impande zamabara, nibisobanuro bitari byo

Gukemura mask bigenzura aho gukorera mu mucyo guhinduka. Ntabwo ikuraho mu buryo butaziguye ibara rya kera ryibara rimaze kuvangwa mu nkomoko ya pigiseli. Mask ifite ishusho nziza irashobora kwerekana halo yijimye cyangwa ifite amabara mugihe isoko yafotowe inyuma ikomeye.

Kugabanya mask birashobora guhisha iyo mpande ukata mumutwe. Kwaguka birashobora kubika amakuru arambuye kandi menshi ashaje. Gukosora neza kuringaniza imiterere namabara kubunini bwerekanwe.

Niyo mpamvu umubare umwe ntarengwa ushobora kwemeza kohereza ibicuruzwa hanze. Ubwiza bwimpande bukomatanya mask geometrie, alfa igice, ibara ryinkomoko, ibisohoka inyuma, hamwe nubunini bwo kureba.

Igenzura rifatika ryohereza hanze

Mbere yo kohereza ibicuruzwa byingenzi:

1. Emeza ko ibipimo byerekana mask yatunganijwe neza.
2. Huza ishusho hanyuma urebe ingingo rusange.
3. Kwegera umusatsi, ubwoya, ibintu bito, icyuho, nigicucu.
4. Hindura hagati yumucyo numwijima.
5. Garuka kumubare wagenewe gukoreshwa.
6. Kohereza no kugenzura PNG nyayo aho igana igihe bishoboka.

Niba ishusho yatumye kugabanuka-gukemura bitunganijwe, witondere cyane hafi yamakuru arambuye. Intoki Ongeraho no Gusiba kunonosora birashobora gukosora intego, ariko ntishobora kongera gukora amakuru atagaragara mumasoko.
