Izvo pane-mudziyo yekucheka modhi inoona

By Technical specialist

Pa-device cutout modhi haione munhu, shangu, chipfuyo, kana chigaro mupfungwa yemunhu. Iyo inogamuchira nhamba inomiririra yemufananidzo uye fungidziro, pixel nepixel, idzo nzvimbo dzinogona kunge dziri dzechidzidzo chikuru. Kuburitsa kwayo kunobatsira ndeye mask: mepu yegreyscale inogona kuve nzira yekujeka yemhedzisiro.

Musiyano iwoyo unotsanangura zvese kumhanya kweotomatiki cutouts uye miganhu yavo. Iyo modhi inogona kushandisa maitiro ekuona akadzidzwa panguva yekudzidziswa, asi haizive chinangwa chako. Chinhu chinopinza chiri pedyo nepakati chinogona kutaridzika chakakosha; rimu regirazi risina kusimba kana kuti vhudzi rakasununguka rinogona kutaridzika semashure.

Kubva pafaira remufananidzo kuenda kumodhi yekuisa

Iyo faira yaunosarudza kutanga inofanirwa kudhindwa. Mufananidzo wakamanikidzwa hauna kupfuudzwa zvakananga mumuenzaniso sebhuroka yemabhayiti emafaira. Iyo bhurawuza inoishandura kuita pixels nehupamhi, kureba, uye kukosha kwemavara.

Iyo pombi yekufungidzira inozogadzira yemhando-saizi yekupinza. Zvichienderana nemuenzaniso uye nguva yekumhanya, kugadzirira kunogona kusanganisira:

• kudzoreredza mufananidzo wakadhindwa kune zviyero zvinotarisirwa nemuenzaniso;
• kuronga dzvuku, girini, uye bhuruu kukosha senhamba chiteshi;
• kuyera kana kuenzanisa izvo zvakakosha;
• kuarongedza kuita tensor, iyo array fomati inoshandiswa neiyo inference runtime.

Iwo chaiwo dimensions uye normalization mitemo ndeyekutevedzera modhi. Chinhu chakakosha chinoshanda ndechekuti inference inowanzo shanda kubva kune yakagadzirira inomiririra, kwete kubva kune yega sosi pixel pakukura kwayo kwepakutanga.

Easy Background Remover inomhanyisa nhanho iyi yekufungidzira mubrowser ine pane-mudziyo segmentation modhi. Iyo modhi faira ingangoda kudhawunirodha isati yatanga kuchekwa, asi nzira yekugadzira mifananidzo yakagadzirirwa kuramba iri munharaunda kana modhi yagadzirira. Iyo modhi yekurodha chikumbiro cheasset; hachisi chinhu chakafanana nekuisa iyo yakasarudzwa foto yekuremerwa inference.

Izvo zvinobuda ndeyekuvimba-kunge mask

Kune imwe neimwe nzvimbo mukubuda kwayo, modhi inoburitsa kukosha kunogona kududzirwa sechinhu chakanyanya-sechidzidzo-chakaita kana chakawanda kumashure-sekunge. Zvinobatsira kufungidzira izvi semufananidzo wegreyscale:

• chena zvinoreva chengetedza nzvimbo iyi;
• dema zvinoreva kubvisa nzvimbo iyi;
• grey zvinoreva kuvharika zvishoma kana kusava nechokwadi pedyo nekumucheto.

Iyo bhurawuza inoshandura iyo inobuda kuita inoshanda alpha mask. Iwo epakutanga eruvara pixels anogona zvino kuumbwa pamusoro pechekibhodhi, kuzadza kwakasimba, gradient, kana mumwe mufananidzo. Kutumira kunze pachena kunochengeta mask se alpha pane kupenda chekibhodhi mufaira.

Zvinyoro zvinyoro zvine basa. Kana kukosha kwemasiki yega yega ikamanikidzwa pakarepo kuita nhema nhema kana chena, bvudzi, makushe, machira eshinda, kusviba kwekufamba, uye mipendero isina kusimba yaizooma zvisingaite. Partial alpha inogona kuchengetedza shanduko iri nyore. Inogona zvakare kuburitsa mupendero wemavara kubva kumashure kwekare, ndosaka mhedzisiro ichiri yakakodzera kutariswa kwekuona.

Ndeupi humbowo hwekuona hunobatsira modhi

Iyo segmentation modhi inogona kudhirowa pane inodarika imwechete clue kamwechete. Zviratidzo zvakasimba zvinowanzobatanidza:

• musiyano pakati pechidzidzo uye kumashure;
• miganhu inoenderera yakapoteredza chinhu chikuru;
• musanganiswa wakajairika wechimiro, magadzirirwo, uye chinzvimbo;
• kudzika kwakadzika senge misiyano yekutarisa;
• matunhu anoonekwa ari pamwechete.

Hapana chimwe chezvibodzwa izvi chiri vimbiso. Bhachi rakasviba rakatarisana nemadziro erima rinopa muganhu usina simba kusiyana. Chigaro chine maburi madiki chinogona kunge chine nzvimbo dzekumashure dzakafanana nechinhu. Mamiriro ekumashure anogona kukwikwidza nechidzidzo chaicho kuti atariswe.

Iyo modhi iri kuita yakanakisa fungidziro kubva kune iripo pixels. Haikwanise kuwanazve ruzivo rusina kumbotorwa mufananidzo.

Izvo iyo modhi isingazive

Iyo modhi haingozive kuti ndechipi chinhu chawaida kuchengeta kana zvidzidzo zvakawanda zviripo. Hazvizivi kuti girazi rekunwira rinoonekera rakakosha mune zvekutengesa, kuti mumvuri unofanirwa kugara nekuda kwechokwadi, kana kuti tambo diki ndeyebhegi.

Iyo zvakare haigamuchire yakavanzika yakakwirira-resolution vhezheni yeblurry sosi. Mabhuroki ekudzvanya, akachekwa mapeji, kusajeka kwekufamba, uye zvidiki zvidiki zvinomisa humbowo huripo. Kuwedzera yekutarisa zoom kunoita kuti mapixels akakura pachiratidziri; haigadziri ruzivo rusipo.

Ichi ndicho chikonzero “AI yakazviona” uye “mupendero wakagadzirira kushambadza” zvirevo zvakasiyana. Kuona kunotanga kugadzirisa. Kuongorora kunopedza.

Nei zvakatetepa uye zviri pachena zvinhu zvakaoma

Zvinhu zvitete zvinotora mapixel mashoma. Kana mufananidzo ukadzoserwa saizi yekufungidzira, waya yepixel imwe kana tambo yebvudzi inogona kuenzana nekumashure kwakaitenderedza. Zvinhu zvakajeka zvakaoma kune chimwe chikonzero: ruvara rwavo runooneka chikamu chekare. Muganhu unogona kujeka kune munhu anonzwisisa chinhu, nepo pixel patani inoramba isina kujeka.

Mimvuri yakapfava inogadzira kusajeka kwemaune. Mupendero wadzo wekunze unopera zvishoma nezvishoma, uye hapana kana imwe chete yakaringana yekucheka. Kuchengeta mumvuri wakazara kunogona kutaridzika sechisikigo pane yakafanana kumashure asi yakasviba pane inopenya nyowani yekuzadza. Kuibvisa kungaita kuti nyaya yacho iite seyayangarara.

Aya ndiwo matambudziko ekutonga sematambudziko emuenzaniso.

Model mask, kushanda mask, uye ekisipoti mask

Inobatsira kuparadzanisa matanho matatu:

1. Modhi mask: iyo otomatiki estimate yakadzoserwa nekufungidzira.
2. ** Mask inoshanda: ** iyo mask inoratidzwa mupepeti mushure mekuwedzera kana Dzima kunatsiridza.
3. ** Export mask: ** mask yekushanda inoshandiswa kana chigumisiro chezvino chatorwa kana kukopwa.

Mu Easy Background Remover, kunatswa kwebhurashi kunogadzirisa mask inoshanda. Export inoshandisa yazvino yakagadziridzwa mhedzisiro pane kudzoka chinyararire kune isina kubatwa otomatiki mask. Izvi zvinobvumira iyo modhi kubata kupatsanurwa kwakakura iwe uchigadzirisa zvinhu zvinoenderana nechinangwa.

Iyo inoratidzwa preview inogona kuyerwa kuti ikwane mupepeti. Iyo saizi yekuratidzira haisi chiyero chakavimbika chemukati weiyo mask. Verenga Mask resolution vs preview size kuti uwane musiyano.

Inference yemunharaunda ichine nhanho yekuseta

Kumhanyisa modhi pa-mudziyo kunoda huremu hwemodhi uye inoenderana browser yekumhanyisa nguva. Huremu hwakakura kupfuura yakajairwa interface kodhi, saka kurodha zvese pane yega edhita kuvhurwa kungave kutambisa. Chikamu chekutanga chinogona kurodha uye cache modhi; mashure enguva dzose anogona kuishandisa zvakare.

Sei watanga kudhaunirodha modhi inotsanangura muganhu iwoyo pasina kuvhiringa kudhaunirodha kwemodhi nekuisa mufananidzo. Heavy inference inomhanyawo kubva kune main interface thread; ona Web Worker image processing basics.

Nzira inoshanda yekutonga mhedzisiro

Usatarise pakati pechidzidzo chete. Tarisa mask pane humbowo husina kusimba:

• bvudzi, mvere, ndebvu, uye machira eshinda;
• magirazi, tambo, waya, uye mapeji akamanikana;
• pasi-kusiyanisa mipendero;
• semi-pachena zvinhu;
• kuonana mimvuri;
• makona apo ruvara rwekare rwekare runogona kusara.

Wona mhedzisiro pane zvese mwenje uye nerima kumashure kana kwekupedzisira kusingazivikanwe. Halo yakachenuruka inogona kunyangarika pachena uye inova pachena pane dema. Wonatsa chete nzvimbo dzine chekuita nekushandiswa kwakarongwa.

Otomatiki segmentation inonyanya kubatsira kana ichibatwa seyakasimba yekutanga pass, kwete chirevo chekunzwisisa kwakakwana. Kuti uedze kuchekwa kuzere uye kukwenenzvera kuyerera, ona Tanga.
