I-Photoshop isebenzisa i-algorithm engaqondakali ukuze izithombe zebhange zingavulwa

Uma nganoma yisiphi isizathu nganoma yisiphi isikhathi sizamile ukuvula isithombe semali yasebhange nge Photoshop graphic design application, sizobe sihlangane nesimanga esingajabulisi. Isizathu salokhu kungenzeka ukuthi uhlelo luthumela isexwayiso esingavumeli ukusebenza ngezithombe ezihlobene nemali.

Lokhu kungenxa yokuthi ku-Photoshop, i-algorithm yethulwe enguqulweni yayo ye-CS ekwazi ukuthola izithombe ezibhekisele kuhlamvu lwemali. Kule ndatshana sichaza ngokuningiliziwe isizathu sokuthi kungani i-Photoshop isebenzisa i-algorithm engaqondakali ukuze izithombe zebhange zingavulwa.

Uma nganoma isiphi isikhathi sihlangane naleli phutha, sizobe siqaphele ukuthi uhlelo lusikhombisa i-URL esiqondisa kabusha ukuze sazi imininingwane eminingi maqondana nalokhu (www.lolusicusa.org). Le webhusayithi ngeka- ICentral Bank Deterrence Group noma futhi yaziwa ngegama layo eliyisifinyezo i-CBCDG, le yinhlangano ebandakanya amabhange amakhulu angama-27 futhi igxile empini yokulwa nomgunyathi wedijithali wemali.

Ngaphezu kwalokho, babhekene nezinhlelo ezifana ne- Photoshop, Corel Dweba noma Paint Shop Pro, babe nalolu hlelo lokuthola ngaphandle kwabadali bohlelo ngokwabo abanolwazi lokuthi i-algorithm ngqo abayinikezwayo isebenza kanjani. Ngonyaka wama-200 kwaba yisikhathi lapho i-Photoshop yaqala ukusebenzisa lolu hlelo lokutholwa, umphathi womkhiqizo wenkampani i-Adobe ubize lokhu njenge indlela yebhokisi elimnyama, lapho okuqukethwe enakho kungaziwa.

Lapho umqondisi oshiwo ngenhla ebuzwa ngesizathu sokusebenzisa le algorithm, uphendule wathi “Njengomholi wemakethe nezakhamizi ezinhle, kubonakala sengathi senza into efanelekile nje”. Futhi-ke, ngokomthetho uthi onjiniyela ababophezelekile ukukwazi ukusebenzisa ukulawulwa okunje, kepha bathathe isinqumo sokwamukela lesi sicelo ku-CBCDG futhi basifaka.

Ngendlela efanayo kuyenzeka nabanye izinhlelo zokwakhiwa kwemidwebo.

Ekuqaleni bekucatshangwa ukuthi i-algorithm yayenzelwe ukuthola iphethini ethile nangokuhlelwa okufana ncamashi nomlaza i-Orion, yingakho leli phethini laziwa ngokuthi i-constellation ye-EUrion, ngoba imvamisa yonke imali engamaphepha inephethini lamaphoyinti amahlanu.

Umphenyi UMarkus Kuhn, nguyena owathola iphethini ngengozi ngo-2002, ngenkathi enza ucwaningo esebenzisa iphrinta entsha yeXerox, okuyi unqabile ukukwazi ukuphrinta ithikithi. Izimo okumele la maphuzu amahlanu abe nazo ukuze zitholakale ziseyindida, umcwaningi uKuhn uchaze kwinhlolokhono muva nje, isithombe sinombala omnyama nomhlophe, i-algorithm ayitholakali, kepha uma kutholakala uhlobo oluthile lombala lungatholakala.

Ngale ndlela, ibanga elingaba khona phakathi kwephoyinti ngalinye nalo alaziwa futhi lokhu kungenye imininingwane ebhekwayo.

Kwabaningi, izindandatho ze-omron yizo ezenza i-Photoshop yazi uma kukhulunywa ngesithombe somthethosivivinywa, kepha impendulo yalokhu ngu-Cha noma okungenani akuyona uhlelo kuphela olwenziwayo. Umcwaningi wase-University College London uSteven J. Murdoch wenze izivivinyo nge Isitolo se-Photoshop ne-Paint ngemuva nje kwalezi zinhlelo ikheli labo le-algorithm. Wamangala uSteve, lapho izindandatho zezinkanyezi sezimboziwe, izinhlelo zazisathola lo mthethosivivinywa futhi isithombe sasingakwazi ukuhlelwa.

Kulolu vivinyo, kutholakale ukuthi ubuchule be-Photoshop ne-PSP bunemiphumela efanayo.

Ngaphandle kwalokho, isikhathi sokubuyisa iphutha besincike esithombeni esihlaziyiwe nokuthi lapho kwenziwa konke lokhu kuhlolwa kanye nophenyo, uMurdoch uqinisekise ukuthi inkampani yakwaDiginarc isidalile uhlelo oluthuthukile oluvumela ukutholwa kwemali engamaphepha.

Ekuphetheni, i-Photoshop isebenzisa i-algorithm engaqondakali ukuze izithombe zebhange zingavulwa, ngoba ngenxa yezizathu zokuphepha sekuqalisiwe ukuze imali engamaphepha ingafakwanga ngamadijithi.
