Iphinda ibuye izithombe isebenzisa indlela yokubola yemvamisa

Ukuwohloka kwemvamisa kwesithombe "ukwahlukanisa" ukuthungwa (kithi, isikhumba) emthunzini noma ithoni yaso. Lokhu kwenziwa ukuze sikwazi ukushintsha izakhiwo zesikhumba ngokwehlukana. Isibonelo, uma uphinda ubambe ukuthungwa, ithoni izogcina ingabonakali futhi iphambene nalokho.

Ukuphinda usebenzise i-frequency decomposition way inqubo ekhathazayo futhi eyisidina, kepha umphumela ungokwemvelo kunokusebenzisa ezinye izindlela. Ochwepheshe basebenzisa le ndlela ethile emsebenzini wabo.

Indlela Yokubola Okuvamisile

Umgomo wendlela ukwakha amakhophi amabili wesithombe soqobo. Ikhophi lokuqala liphethe imininingwane ngethoni (ephansi), kanti eyesibili imayelana nokuthungwa (phezulu).

Bheka indlela usebenzisa isibonelo sengxenye yesithombe.

Umsebenzi wokulungiselela

1. Esigabeni sokuqala, udinga ukudala amakhophi amabili ungqimba lwangemuva ngokucindezela inhlanganisela yokhiye kabili I-CTRL + J, bese unikeza amakhophi amagama (chofoza kabili egameni lesendlalelo).

   

2. Manje cisha ukubonakala kwengqimba ephezulu enegama elithi "ukuthungwa" bese uya ungqimba ngethoni. Le ungqimba kufanele ihlanzwe kuze kuphele konke ukushiyeka kwesikhumba okuncane.

   Vula imenyu "Isihlungi - Blur" bese ukhetha UGaussian Blur.

   

   Sibeka irediyasi yokuhlunga ukuze, njengoba sekushiwo ngenhla, amaphutha anyamalale.

   

   Inani lerediyo kufanele likhunjulwe, ngoba sisalidinga.

3. Qhubeka. Iya kungqimba yokufakwa bese uvule ukubonakala kwayo. Iya kumenyu "Isihlungi - Okunye - Umbala Ohlukile".

   

   Hlela inani lerediyo lifane (lokhu kubalulekile!), Njengasekuhlungweni UGaussian Blur.

   

4. Ngqimba lokugcwala, shintsha imodi yokuhlanganisa ibe Ukukhanya komugqa.

   

   Sithola isithombe ngemininingwane yokugcwala ngokweqile. Lo mphumela kufanele ube buthaka.

5. Faka isendlalelo sokulungiswa Curves.

   

   Ewindini lezilungiselelo, yenza kusebenze (chofoza) iphoyinti elingezansi kwesokunxele bese, enkambu "Phuma" nikeza inani 64.

   

   Ngemuva kwalokho senza kusebenze iphuzu elingaphezulu eliphezulu bese sinquma inani lokukhipha elilingana nalo 192 bese uchofoza inkinobho yokuthwebula.

   

   Ngalezi zenzo, sinciphise umphumela wokungqanjwa kokugcwala kwizendlalelo ezingaphansi ngesigamu. Ngenxa yalokhu, sizobona isithombe endaweni yokusebenza okufana ngokuphelele nokwasekuqaleni. Ungahlola lokhu ngokubamba ALT bese uqhafaza isithonjana seso kusendlalelo sangemuva. Akufanele kube nomehluko.

Ukulungiselela ukuphinda uqeda ukuphothula kuqediwe, ungaqala ukusebenza.

Iphinda ibuye ukuthungwa

1. Iya kusendlalelo ukuthungwa bese udala isendlalelo esisha esingenalutho.

   

2. Sisusa ukubonakala kusuka kungqimba lwangemuva kanye nesendlalelo setoni.

   

3. Khetha ithuluzi Ukupholisa uBhulashi.

   

4. Kumasethingi asephaneli ephezulu, khetha "Ungqimba olusebenzayo nangaphansi", ngokwezifiso ifomu, njengasesikrinini.

   

   Usayizi wokuxubha kufanele ulingane cishe nosayizi omaphakathi wesiphene esihleliwe.

   

5. Ukuba kusendlalelo esingenalutho, bamba ALT futhi uthathe isampula yokuthungwa eduze kwesici.

   

   Bese uqhafaza kwisiphene. I-Photoshop izobuyisela ukuthungwa ngokuzenzakalela nenye ekhona (isampula). Senza lo msebenzi nazo zonke izindawo eziyinkinga.

   

Ukuvuselelwa kwesikhumba

Siphinde saguqula ukuthungwa, manje sebenza ukubonakala kwezendlalelo ezingezansi bese siya ungqimba ngethoni.

Ukuhlela ithoni kuyefana, kepha usebenzisa ibhulashi ejwayelekile. I-algorithm: khetha ithuluzi Ukuxubha,

setha opacity 50%,

ukubambelela ALT, ukuthatha isampula bese uqhafaza endaweni yenkinga.

Lapho uhlela ithoni, ochwepheshe baphendukela kubuqili obuhehayo. Uzosiza ukonga isikhathi nezinzwa.

1. Dala ikhophi yesendlalelo sangemuva bese uyibeka ngaphezulu kwesendlalelo sethoni.

   

2. Ikhophi kaBlur Gaussian. Sikhetha irediyo enkulu, umsebenzi wethu ukwenza bushelelezi isikhumba. Ukuze kube lula ukuqonda, ukubonakala okuvela kungqimba ephezulu kungasuswa.

   

3. Bese uchofoza isithonjana semaski ngokhiye ocindezelwe ALTukudala imaskhi emnyama nokufihla umphumela. Vula ukubonakala kwezendlalelo ezingenhla.

   

4. Okulandelayo, thatha ibhulashi. Izilungiselelo ziyafana nangaphezulu, futhi khetha umbala omhlophe.

   Ngalesi brashi sidabula izindawo ezinenkinga. Sisebenza ngokukhulu ukucophelela. Uyacelwa ukuthi uqaphele ukuthi lapho kufiphala, kube khona ukuxubana okwenziwe ngamathoni emingceleni, ngakho-ke ungazami ukuxubha kulezi zindawo ukugwema ukubonakala “njengodaka”.

   

Kulesi sifundo esiphindaphindayo ngendlela yokubola imvamisa kungabhekwa njengokuqediwe. Njengoba kushiwo ngenhla, indlela le iyakhandleka impela, kodwa iyasebenza. Uma uhlela ukuhlanganyela ekucutshungweni kwezithombe zobuchwepheshe, khona-ke ukufunda ukubethela imvamisa kubalulekile.
