Igisubizo c’igipfukisho vs ubunini bw’imbere

By Technical specialist

Igishushanyo c’amamasiki n’ubunini bw’imbere y’igihe birafitaniye isano, ariko si ingero imwe. Igisubizo c’ibara ry’agahama kidondora uruzitiro rwa pixel rubika ivyerekeye ikintu. Ingano y’imbere y’igihe idondora ingene umuhinduzi ashushanya igisubizo ku mugaragaro wawe. Igishushanyo c’imbere c’amapixel 300 gishobora guserura ishusho n’igipfukisho kinini cane; gukuraho iyo mbonerahamwe ntikwongera amakuru mashasha y’ibara ry’umubiri.

Gutera urujijo ivyo bibiri birashobora gutuma umuntu ashika ku nsozero zitari zo. Igipande coshobora gusa n’ikiryoshe iyo gishizwe ku gipande gitoyi maze kigahishura urumuri ku rugero rwo gushora hanze. Bishobora kandi gusa n’ibiteye igomwe iyo ukoresheje zoom nyinshi cane naho izo pixels z’amabara y’umuntu ku giti ciwe zitaboneka mu gukoresha mu buryo busanzwe.

Ingano zitatu zishobora kubaho mu guhindura kumwe

Umucukumbuzi wo gucapura urugendo rw’akazi rushobora kubamwo nibura ibibanza bitatu:

  1. Ingano y’inkomoko: ubwaguke n’uburebure bw’ishusho yatowe.
  2. Inference canke working mask size: uruzitiro aho ivyigwa bifatwa biharurwako bigahindurwa.
  3. Ingano y’imbere: igishushanyo c’urugero gihuye n’aho umuhinduzi ariho.

Ivyo bipimo birashobora guhura, ariko ntibitegerezwa guhura. Inkomoko nini ishobora kugabanywa imbere kugira ngo haboneke ingero z’akarorero kugira ngo zigenzure igihe co gukora n’ukwibuka. Ico gipfukisho gishobora rero gushirwa mu kibanza co gukoreramwo canke co gusohora hanze. Ubwa nyuma, umucukumbuzi arasubira gupima iyo nkuru kugira ngo ijyane n’ivyo bigaragara.

Easy Background Remover ishobora gukora amashusho manini cane ku nzira y’imbere igabanutse kandi yerekana imburi. Ivyoherezwa hanze biracari vyerekeye ingero z’inkomoko. Ivyo bituma ibipimo vy’isohoka biguma ari ngirakamaro, ariko ntibishobora guhingura ido n’ido ry’urubibi ryari ritari mu gipfukisho caharuwe imbere.

Mbega pixel y’ibara ry’umubiri ibika

Igipfukisho c’umubiri si ngombwa ngo kibe igishushanyo c’umwirabura canke c’umweru. Buri pixel y’igipfukisho ishobora gufata agaciro ka alpha kuva inyuma biciye mu gupfuka igice gushika ku ciyumviro kigumye.

Ku ruhande rw’ikintu gikomeye, iyo mpinduka ishobora gufata gusa umurongo mutoyi. Ku mushatsi woroshe, ubwoya, gupfukirana, canke igitutu, agaciro k’igice k’ingirakamaro gashobora gushika ahantu hagari. Iyo igipfukisho gihinduwe ingano, interpolation igereranya agaciro hagati y’ibigereranyo vy’igipfukisho c’intango.

Gushiramwo amajambo birashobora gutuma uguhinduka kugaragara neza. Ntishobora gusubirana uburyo nyabwo bw’urudodo rwazimiye mu gihe c’ugushiramwo ivyiyumviro bifise ubushobozi buke. Ugusenyera neza n’ugusubirana ido n’ido ni kamere zitandukanye.

Kubera iki ivyerekanwa vy’imbere bihisha utunenge

Iyo umuhinduzi ashize ishusho nini mu gice gitoyi, amapixel menshi y’inkomoko aratanga umusanzu kuri buri pixel yerekanwa. Utunogo dutoduto, imirongo y’ipixel imwe, n’urudome rutaringaniye birashobora gufatwa kure.

Ivyo ni ngirakamaro ku bijanye n’uguhingura: urashobora guca urubanza nimba ikiganiro kiri hagati be n’uko ugutandukanya kwagutse ari ukuri. Ntibihagije ku bijanye n’uburyo bwo ku ruhande.

Isubiramwo ryizigirwa rikoresha urugero rurenga rumwe:

Iyo iyo shusho izocika avatar ntoyi, akaga gatoyi gashobora kutazokwigera kagira akamaro. Iyo izocapwa nini canke ishizwe hejuru y’ibintu vy’umwiza, ako gasembwa nyene karashobora kugaragara.

Kuki zoom ishobora gutuma urubibi rwiza rusa nabi

Ku zoom nini, umuhinduzi aragwiza ama pixels atandukanye. Intambwe z’ingazi zitegerezwa ku mipaka y’uburinganire n’iyigoramye kubera ko uruzitiro rw’ibipimo rudakomeza. Ihinduka ryoroshe rishobora kandi gusa n’umurongo w’imvi uboneka iyo pixel yose yagutse.

Ikibazo si uko ama pixels aboneka ku 800 kw’ijana. Bazobigira. Ibibazo vy’ingirakamaro ni ibi:

Ntufute ama pixels yoroshe kubera gusa asa n’imvi ku kibaho c’amabara iyo ukoresheje zoom nyinshi cane. Mubanze mugerageze ku bijanye n’aho muzoja.

Ingano z’inkomoko ntizitanga ido n’ido ry’urugero rw’inkomoko

PNG yoherejwe hanze ishobora kugira ubwaguke n’uburebure nk’ubw’inkomoko mu gihe igipfukisho cayo ca alpha cakomotse ku rwego rwo hasi. Gutera imbere kw’ikarata zipfuka amabara y’ubunini bushitse. Ingano za dosiye ziguma zigororotse, ariko ukuri kw’imipaka kuragabanywa n’amakuru ari mu gipfukisho c’ubushobozi bwo hasi n’ugutunganya kwose kwa nyuma.

Ivyo bisa n’ugushushanya urutonde rworoshe ku mpapuro z’igishushanyo maze ukarugwiza. Ico gicapo cagutse kirashobora gusenyerwa, mugabo ntikironka amagobe atarigeze ashushanywa.

Ivyo ntibituma inference igabanutse iba ata co imaze. Ivyigwa vyinshi birafise imirongo igaragara kandi yagutse, kandi ubunini bw’imbere bubereye burashobora gutuma haba uburinganire bwiza hagati y’umuvuduko, ugukoresha ubwonko be n’uburyo. Bisigura ko utudondozi dutoduto dukwiye kwitwararikwa cane.

Amaboroshe arakeneye guhuza ikarita

Iyo usize Yongera canke Gukuraho imirongo ku mbonerahamwe, umuhinduzi ategerezwa gusubiza ikarita y’ibimenyetso ku gipfukisho gikora. Igiharuro c’uburoso na co nyene gikeneye insobanuro idahinduka. Uruziga rw’ibipimo cumi ku rubuga ntirukwiye guhinduka mu mpanuka uguhindura kw’umubiri gutandukanye rwose kubera gusa ko ivyerekanwa vyahinduwe.

Ikarita nziza y’amakonti ya:

Ubutandukane buto buto bwo gukikuza ntibushobora kwirindwa, ariko gusubiramwo gutera bikwiye gushika aho ikimenyetso kigaragaza. Niba igicapo kigaragara ko gihindutse, banza usuzume nimba igipande cari carahinduwe canke nimba ugukura kw’umucukumbuzi kwahinduye uko giteye imbere y’uko wiyumvira ko igipfukisho c’akarorero ari ikinyoma.

Inyuma y’umuco n’umwiza bigaragaza ama pixels atandukanye

Ivyuma vy’amabara bimenyesha uguserukira abantu, ariko si ikigeragezo c’uburyo co gupima abantu bose. Amasigarira y’ibara ry’agahama ava ku mfuruka yera arashobora kwivanga mu bipande vy’umuco. Igipande c’umwirabura gishobora kuzimangana ku bibanza vy’umwirabura.

Suzuma iyo nzira nyene kuri:

Urubibi rukora ku bintu vyose bitatu ni rwo rukomeye kuruta. Nimba igisohoka ca nyuma cama gikoresha ukuzuza kumwe kudahinduka, nushiremwo ivyiza ku bijanye n’aho uja aho gukurikirana ubutungane bw’ivyiyumviro hose.

Amamasiki, ibara ry’uruzitiro, n’ukuri kw’ibinyoma

Igisubizo c’amamasiki kigenzura aho uguseruka guhinduka. Ntibikuraho ibara rya kera ry’inyuma ryamaze guvanzwa mu bipimo vy’urubibi rw’inkomoko. Igipfukisho gifise ishusho ibereye kirashobora kuguma kigaragaza urumuri rw’agahama canke rw’ibara ry’agahama igihe iyo soko yafotorwa iri ku mfuruka ikomeye.

Gucapura iyo mask birashobora guhisha iyo nzira mu guca mu ciyumviro. Kuyagura vyoshobora kuzigama ibintu vyinshi vy’ido n’ido be n’ibara rya kera. Gukosora gukwiriye kuringaniza uburyo n’ibara ku rugero rw’aho umuntu aja.

Ni co gituma urugero rumwe rw’umubare rudashobora gutanga icemeza ko ivyoherezwa hanze bisukuye. Ubwiza bw’urubibi buhuza uburebure bw’igipfukisho, igice c’inyuguti, ibara ry’inkomoko, inyuma y’isohoka, n’urugero rwo kuraba.

Igenzura ry’ivyoherezwa hanze

Imbere yo kohereza hanze igice gihambaye:

  1. Wemeze ko ivyerekanwa vyerekana igipfukisho c’ubu gitunganijwe.
  2. Shira ishusho maze usuzume ikiganiro muri rusangi.
  3. Zoom mu mushatsi, ubwoya, ibintu bitobito, ibihengeri, n’ibitutu bikorana.
  4. Hindura hagati y’inyuma y’umuco n’inyuma y’umwiza.
  5. Subira ku rugero rw’ikoreshwa ry’ivyo wipfuza.
  6. Gusohora hanze no gusuzuma PNG nyayo aho ija iyo bishoboka.

Nimba ishusho yatumye habaho ugutunganya ivyiyumviro bigabanutse, urabe maso cane cane ku bijanye n’ibintu bitobito. Kwongera no Gukuraho amakuru bikoreshwa n’amaboko birashobora gukosora umugambi, ariko ntibishobora gusubira kurema amakuru ataboneka mu nkomoko.

Ku bijanye n’inzira y’ibara ry’umubiri, raba Ivyo igishushanyo c’igikoresho kibona. Kugira ngo utahure igituma gusubiramwo imiterere bishobora gusaba ivyinjijwe n’amaverisiyo bigenzurwa, soma Ivyoherezwa hanze bishobora gusubirwamwo n’imiterere imwe.
