Pakupedzisira, vaongorori vaigona kushandisa izvi uploaded mapikicha kusika yakakwirira chisarudzo 3D yokutevedzera zvezvivako zvose pazvikoro (Figure 5.12).

Figure 5.12: The PhotoCity mutambo kuti vatsvakurudzi uye vatori vechikamu kuti kusika yepamusoro 3D yokutevedzera zvezvivako vachishandisa mifananidzo uploaded kuburikidza vechikamu (Tuite et al. 2011) .

Magadzirirwe PhotoCity Washington anogadziriswa matambudziko maviri: date chivimbo chakasimba uye zvakabudiswa. Chokutanga, mapikicha vakanga yakasimbiswa kuburikidza chienderane navo pamusoro yapfuura mapikicha dzaiva jana vachiwirirana kuna yapfuura mapikicha yose nzira kudzokera mbeu mapikicha vakanga uploaded kubudikidza nevatsvakurudzi. Nemamwe mashoko, nokuti redundancy ichi yakavakwa-mukati, zvakaoma chaizvo kuti hurongwa kugamuchira mashoko akaipa. Chechipiri, scoring hurongwa muropa inodzidzisa vatori kuunganidza chinokosha kwete vakawanda zvikuru kureruke-mashoko. Kutaura zvazviri, hezvino zvimwe nzira kuti vatambi akarondedzera kushandisa kuti awedzere pfungwa, izvo yakaenzana nekunhonga Data kukosha (Tuite et al. 2011) :

• "[Ndakaedza] paiva nguva zuva uye chiedza kuti mapikicha akatorwa; izvi zvaizobatsira kudzivisa Kurambwa mutambo. With vakati ramakore mazuva aiva akanakisisa nokure kana pakugadzirisa makona nokuti zvishoma musiyano yakabatsira mutambo mufananidzo kunze geometry kubva mifananidzo angu. "

• "Kana kwaive, Ini kushandiswa kamera wangu Anti-kuzungura zvinhu kubvumira pachangu kutora mapikicha apo famba imwe wongoramba. Izvi akabvumira nditore Crisp mapikicha apo vasina kurega stride wangu. Uyewo bhonasi: shoma vanhu zvavakaramba ini "!

• "Kutora mifananidzo chimwe chivako vakawanda 5 megapixel kamera, ipapo kuuya kumba pasi, dzimwe nguva kusvika 5 s pakupera kwevhiki davi, akanga chikuru Photo kubatwa nzira. Kuronga mapikicha ari zvokunze zvakaoma ngarurege folders kubudikidza kembasi nharaunda, kuvaka, ipapo pachiso chivakwa akapa vakuru zvakanaka maumbirwo Uploads. "

Mashoko aya kubva vechikamu inoratidza kuti kana vari inopiwa zvakakodzera inofambiswa, vanogona kuva zvikuru nyanzvi pane nekunhonga mashoko dzinofarirwa nevaongorori.
