Lines da ƙarin ratsi a hankali a hankali zuwa siffar ido wanda idan muka kalleshi daga nesa ko akaɗa zuƙowa, zamu iya gano yadda shuɗin yake ƙara bayyana. Baya ga wannan yana da launi a cikin babban rukuni na hotuna tare da sautin mai haske.
Abu mai ban sha'awa game da wannan gwajin da aka yi a cikin alkalami shine cewa akwai hanya don ƙirƙirar wannan tasirin ta hanyar dijital ta hanyar bin kwatankwacin lankwasan siffofin ido ko na abin da muke son wakilta. Shawara mai ban sha'awa daga wani mai fasaha wanda ba a san sunan sa ba a yanar gizo wanda ya dace daidai da sanin RANSAC algorithm.
Hanyar yi shi ta hanyar dijital ana iya takaita shi azaman:
- Maida hoto zuwa fari da fari
- Createirƙiri zane mai fanko
- Zana layi ɗaya a kan copiesan ɗari ɗari na zane
- Lissafa bambanci tsakanin na asali da na gwangwani
- Oneauki ɗaya tare da ƙaramin bambanci
- An maimaita aikin daga mataki na uku kusan sau dubu
An gama gaba ɗaya, ya kamata muyi shi kusan sau ɗari kuma a ƙarshe zaɓi hoton da ya fi dacewa mu kwaikwayi samfurin da za mu yi amfani da shi. Zai zama da ɗan wahala, amma za mu adana kasancewar zana shi da hannu kamar yadda yake faruwa tare da gwajin da muka raba a nan. Ee kana so ka ajiye aikin, zo nan.
A ƙarshe muna magana ne game da RANSAC algorithm cewa Fischler da Bolles ne suka buga shi a cikin 1981 kuma tun daga wannan an yi amfani da shi a cikin nazarin hoto. RANSAC yana da kyakkyawar dama don samar da kyakkyawar dacewa daga bayanan da aka gurɓata tare da adadi mai yawa na masu fitarwa, har ma sama da kashi 50 cikin ɗari, wanda shine iyakancewa mara iyaka ga wasu dabarun kimantawa masu ƙarfi.
Algorithm nemi mafi kyawun samfurin la'akari da duk pixels na contour gami da waɗanda basu dace da samfurin da ake nema ba. Ba zato ba tsammani ya zaɓi samfurin s na pixels, tare da kasancewar kasancewar maki da ake buƙata don kafa sigogin ƙirar.
Una tsari mai ban sha'awa mai ban sha'awa a matsayin gwaji. Idan kana son sanin wani, kamar shekara daya da ta gabata mun buga wanda aka yi da CSS3D HTML5.
