Tekinoroji yekukanganisa mafoto nekukanganisa kukanganisa masisitimu ekuzivikanwa kwechiso

Vaongorori kubva murabhoritari SAND Yunivhesiti yeChicago yakagadzira bhuku rekushandisa Fawkes nekuita nzira kukanganisa kwemifananidzo, kudzivirira kushandiswa kwavo kudzidzisa kuzivikanwa kwechiso uye masisitimu ekuzivikanwa kwemushandisi. Pixel shanduko dzinoitwa kumufananidzo, izvo zvisingaoneki kana zvichionekwa nevanhu, asi zvinotungamira pakuumbwa kwemhando dzisina kunaka kana dzichishandiswa kudzidzisa michina yekudzidza masisitimu. Iyo kodhi yekushandisa yakanyorwa muPython uye yakabudiswa pasi peBSD rezinesi. Assemblies yakagadzirirwa yeLinux, macOS uye Windows.

Kugadzirisa mafoto neyakarongwa chishandiso usati washambadzira pasocial network uye mamwe mapuratifomu eruzhinji anotendera iwe kuchengetedza mushandisi kubva kushandisa mafoto data sesosi yekudzidzisa masystem ekuzivikanwa kumeso. Iyo yakatsanangurwa algorithm inopa dziviriro kubva ku95% yekuedza kuzivikanwa kwechiso (yeMicrosoft Azure recognition API, Amazon Rekognition uye Face ++, kuchengetedza kushanda zvakanaka i100%). Uyezve, kunyange kana mune ramangwana mapikicha epakutanga, asina kushandiswa nekushandiswa, anoshandiswa mumuenzaniso wakatove wakadzidziswa uchishandisa shanduro dzakakanganiswa dzemifananidzo, chiyero chekukundikana mukuzivikanwa kunoramba kwakafanana uye inenge 80%.

Iyo nzira yakavakirwa pane chiitiko che "anopikisa mienzaniso", iyo nhanho ndeyekuti shanduko diki mune yekupinza data inogona kutungamirira kukuchinja kunoshamisa mune yekuronga logic. Parizvino, chiitiko che "anopikisa mienzaniso" nderimwe rematambudziko makuru asina kugadziriswa mumashini ekudzidza masisitimu. Mune ramangwana, chizvarwa chitsva chemichina yekudzidza masisitimu inotarisirwa kubuda iyo isina dhizaini iyi, asi masisitimu aya anozoda shanduko huru mukuvaka uye nzira yemhando dzekuvaka.

Kugadzirisa mafoto kunouya pasi pakuwedzera musanganiswa wemapikiseli (masumbu) kumufananidzo, uyo anonzwisiswa neyakadzama muchina kudzidza algorithms semapeteni hunhu hwechinhu chakafananidzirwa uye zvinotungamira mukukanganiswa kwezvinhu zvinoshandiswa kurongedza. Shanduko dzakadaro hadzina kumira mushe kubva kune yakajairwa seti uye dzakanyanya kuoma kuona nekubvisa. Kunyangwe nemifananidzo yepakutanga uye yakagadziridzwa, zvakaoma kuona kuti ndeipi yepakutanga uye iyo yakagadziridzwa vhezheni.

Iwo akaunzwa akanganisa anoratidza kupokana kwakanyanya pakugadzirwa kwezviyedzo zvine chinangwa chekuona mafoto anotyora kuvakwa kwakaringana kwemamodhi ekudzidza muchina. Kusanganisira nzira dzakavakirwa pakusviba, kuwedzera ruzha, kana kushandisa mafirita kumufananidzo kudzvanyirira pixel misanganiswa hazvishande. Dambudziko nderekuti kana mafirita akaiswa, kurongeka kweiyo kudonha kunodonha nekukurumidza kupfuura kuoneka kwepixel mapatani, uye pamwero kana kukanganisa kwakadzvinyirirwa, nhanho yekuzivikanwa haichagone kunzi inogamuchirwa.

Zvinocherechedzwa kuti, semamwe matekinoroji mazhinji ekuchengetedza kuvanzika, nzira yakatsanangurwa inogona kushandiswa kwete chete kurwisa kushandiswa kusingatenderwi kwemifananidzo yeruzhinji mumasisitimu ekuzivikanwa, asiwo sechombo chekuvanza vanorwisa. Vatsvagiri vanotenda kuti matambudziko ekuzivikanwa anogona kunyanya kukanganisa masevhisi echitatu-bato anounganidza ruzivo zvisingadzoreki uye pasina mvumo yekudzidzisa mamodheru avo (semuenzaniso, iyo Clearview.ai sevhisi inopa dhatabhesi rekuzivikanwa kwechiso, yakavakwa anenge mabhiriyoni matatu emifananidzo kubva pasocial network akaiswa indexed). Kana iko zvino kuunganidzwa kwemasevhisi akadaro ane mifananidzo yakavimbika, saka nekushandiswa kweFawkes, nekufamba kwenguva, seti yemifananidzo yakakanganiswa ichave yakakura uye modhi inovaona sechinhu chakakosha pakurongwa. Maitiro ekuzivikanwa emasangano ehungwaru, mamodheru ayo akavakirwa pahwaro hwezvakavimbika zvinyorwa, zvichange zvisinganyanyi kukanganiswa nemidziyo yakadhindwa.

Pakati pezviitiko zvinoshanda zviri pedyo nechinangwa, tinogona kuona chirongwa chacho Kamera Adversaria, kukura mobile app kuwedzera kumifananidzo Perlin ruzha, kudzivirira kurongeka kwakaringana nemichina yekudzidza masisitimu. Kamera Adversaria kodhi inowanikwa paGitHub pasi peEPL rezinesi. Chimwe chirongwa Jekiseni risingaonekwe ine chinangwa chekuvhara kucherechedzwa nemakamera ekutarisa kuburikidza nekugadzirwa kweakakosha mapatani emvura inonaya, T-shirts, majuzi, capes, mapepa kana hati.
