5.4.2 PhotoCity

PhotoCity zochimwazo kumathetsa khalidwe deta ndi zosankhidwazi mavuto mu deta anagawira deta.

Mawebusaiti monga Flickr ndi Facebook amathandiza anthu kuti azigawana zithunzi ndi anzao ndi abwenzi awo, ndipo amapanga mafano akuluakulu a zithunzi zomwe zingagwiritsidwe ntchito pazinthu zina. Mwachitsanzo, Sameer Agarwal ndi anzake (2011) adayesa kugwiritsa ntchito zithunzi izi kuti "Amange Roma Tsiku" pobwezeretsanso zithunzi 150,000 za Roma kuti apange mzinda wa 3D wokonzanso. Kwa nyumba zambiri zojambula zithunzi-monga Coliseum (chifaniziro 5.10) - ofufuza anali atapambana, koma zomangamanga zinasokonekera chifukwa zithunzi zambiri zinatengedwa kuchokera mmalingaliro amodzimodzi, osasiya mbali zina za nyumbayi. Kotero, zithunzi zochokera ku zithunzi zosungira zithunzi sizinali zokwanira. Nanga bwanji ngati anthu odzipereka angathe kuitanitsa zithunzi zofunikira kuti apindule omwe ali kale? Poganizira mofanana ndi zojambulajambula mu chaputala 1, bwanji ngati zithunzi zowonongeka zingapindulitsidwe ndi zithunzi zojambulapo?

Chithunzi 5.10: Kubwezeretsedwa kwa 3D kwa Coliseum kuchokera pazithunzi zazikulu za 2D kuchokera ku polojekiti "Kumanga Roma Tsiku." Zachilombozi zimayimira malo omwe zithunzizo zinatengedwa. Zaperekedwanso ndi chilolezo kuchokera ku html version ya Agarwal et al. (2011) .

Kuti athandize zojambula zambiri za zithunzi, Kathleen Tuite ndi anzake adapanga PhotoCity, masewera ojambula zithunzi. PhotoCity inachititsa ntchito yovuta kwambiri yosonkhanitsa deta-kujambula-kuchitapo kanthu monga masewera, maulendo, ndi mbendera (chifaniziro 5.11), ndipo idayambitsidwa kuyambitsa kumanganso 3D kwa mayunivesite awiri: University of Cornell ndi University wa Washington. Ochita kafukufuku anayamba ntchitoyi polemba zithunzi za mbewu kuchokera ku nyumba zina. Kenaka, osewera pamsasa uliwonse adayang'anitsitsa zochitika zatsopano ndi zomangamanga polemba zithunzi zomwe zinamanganso kumanganso. Mwachitsanzo, ngati ntchito yomangidwanso ya Uris Library (ku Cornell) inali yovuta kwambiri, wosewera mpira amatha kupeza mapulogalamu polemba zithunzi zatsopano. Zina ziwiri za ndondomekoyi ndi zofunika kwambiri. Choyamba, chiwerengero cha mfundo zomwe osewera adalandira zimachokera ku ndalama zomwe chithunzi chawo chinawonjezeredwa kumanganso. Chachiwiri, zithunzi zomwe zidasindikizidwa zinayenera kugwirizanitsidwa ndi zomangamangidwe zomwe zinalipo kuti athe kutsimikiziridwa. Pamapeto pake, ochita kafukufuku adatha kupanga zitsanzo zapamwamba zowonongeka za 3D pamakampu onse awiri (Chithunzi 5.12).

Chithunzi 5.11: PhotoCity inachititsa ntchito yowonongeka yosonkhanitsa deta (mwachitsanzo, kuika zithunzi) ndikusandutsa masewera. Kubweretsedwa ndi chilolezo kuchokera ku Tuite et al. (2011) , chithunzi 2.

Chithunzi 5.12: Masewero a PhotoCity anathandiza akatswiri ndi otsogolera kukhazikitsa zitsanzo zapamwamba zazithunzi za 3D pogwiritsa ntchito zithunzi zojambulidwa ndi ophunzira. Kubweretsedwa ndi chilolezo kuchokera ku Tuite et al. (2011) , chithunzi 8.

Mapangidwe a PhotoCity anathetsa mavuto awiri omwe amayamba kawirikawiri pogawana zosonkhanitsa deta: deta yolondola ndi sampuli. Choyamba, zithunzi zinatsimikiziridwa poziyerekezera ndi zithunzi zapitazo, zomwe zinkafanananso ndi zithunzi zapitazo kumbuyo kwa zithunzi zazithunzi zomwe zidasindikizidwa ndi ofufuza. Mwa kuyankhula kwina, chifukwa cha redundancy yokhazikitsidwa, zinali zovuta kuti wina aike chithunzi cha nyumba yolakwika, mwangozi kapena mwadala. Zopangidwe izi zimatanthauza kuti njirayi imadziteteza yokha pa deta yolakwika. Chachiwiri, olemba masewera omwe amaphunzitsidwa mwachidziwitso kuti atenge zinthu zamtengo wapatali-osati deta yabwino. Ndipotu, ena mwa njira zomwe osewera akufotokozera kugwiritsa ntchito pofuna kupeza mfundo zambiri, zomwe zikufanana ndi kusonkhanitsa deta yamtengo wapatali (Tuite et al. 2011) :

• "[Ndinayesa] kuyandikira nthawi ya tsiku ndi kuyatsa kuti zithunzi unatengedwa; izi zingawathandize kupewa kukanidwa ndi masewera. Ndi kuti anati, mitambo zabwino kwambiri pochita zinthu ndi ngodya chifukwa wochepa kusiyana anathandiza masewera kuzindikira Masamu zithunzi wanga. "

• "Pamene anali dzuwa, I ntchito kamera wanga odana ndi kugwedeza mbali kulola ndekha zithunzi poyenda mozungulira zone makamaka. Izi anandilola kutenga zithunzi khirisipi pamene alibe kusiya stride wanga. Komanso bonasi: kupatula anthu anandiyang'anitsitsa "!

• "Tengani ndi mafanizo ambiri a nyumba ina ndi 5 megapixel kamera, kubwera kunyumba kugonjera, nthawi zina gigs 5 pa mlungu mphukira, anali yaikulu chithunzi adani strategy. Kukonza zithunzi mafoda kunja zovuta galimoto ndi dera komweko, kumanga, ndiye nkhope ya nyumba anapereka wolowezana bwino kutsogolera uploads. "

Mawu awa akusonyeza kuti pamene ophunzira apatsidwa ndemanga yoyenera, akhoza kukhala katswiri weniweni kuti adziŵe deta zosangalatsa kwa ofufuza.

Zonsezi, polojekiti ya PhotoCity imasonyeza kuti sampuli ndi khalidwe la deta sizingathetse mavuto omwe angapezedwe pakugawidwa kwa deta. Komanso, zikuwonetsa kuti ntchito yosonkhanitsa deta sizingowonjezera ku ntchito zomwe anthu amachita kale, monga kuyang'ana mbalame. Pokonzekera bwino, odzipereka angathe kulimbikitsidwa kuchita zinthu zina.
