Kusukela ngo-1991, iNational Institute of Anthropology and History kanye neNational Institute of Astrophysics, Optics and Electronics (INAOE), ngokusebenzisa iNational Library of Anthropology and History kanye nePermanence of the Image Group, ngokulandelana, yasayina isivumelwano ukubambisana ekwenzeni iphrojekthi ephelele yokulondolozwa kwezithombe.
Omunye wemisebenzi emaphakathi yephrojekthi wenziwa ukukhiqizwa kwezithombe ezisezingeni eliphakeme ezivela ekuqoqweni kwama-codex agcinwe yiLabhulali.
Lo msebenzi unenhloso ephindwe kabili: ngakolunye uhlangothi, ukuxhasa ukulondolozwa kwama-codex ngokuthwebula izithombe, ngoba enye yezimfuno ezinkulu kakhulu zokuthintana nalezi zinto ukwenziwa kwezithombe ukuze kufundwe futhi kushicilelwe, kuthi ngakolunye uhlangothi, kwenziwe izithombe ukulungiswa okuphezulu kokuwafaka ekhompyutheni futhi kamuva ukuwayise kuteyipu kazibuthe evumela ukufinyelela kokubonisana kwakho, ngendlela yebhange lesithombe elenziwe ngogesi, ngamazinga ahlukene okuxhumana, lapho umcwaningi angazisebenzisa ngokukhululeka.
Ukuze kuhlangatshezwane nezinhloso ezibekiwe, kwasungulwa iqembu elenza imikhakha eyahlukene elenze ukuthi linakekele zonke izici zesayensi ezifakwe kuphrojekthi, ngezigaba ezahlukahlukene zocwaningo olusetshenzisiwe. Ngokufanayo, imishini, imulsion yezithombe nohlelo lokukhanyisa kwabonakala, okwaholela ekwakhiweni kohlelo lokuthwebula kabusha olukwazi ukukhiqiza umbala namacwecwe amnyama namhlophe amhlophe, ngokulungiswa okuphezulu ngekhwalithi ye-matrix ye-facsimile. . Lolu hlelo lwakhiwe ngemishini ye-optical enekhamera yensimbi, ngefomethi ye-4 × 5,, enelensi ye-apochromatic (okungukuthi, ilensi elungisiwe ukuze ubude bemibala yemibala emithathu eyinhloko bufane indiza egxile) nokusekelwa okuvumela ikhamera ukuthi ibekwe kwi-xy axis ukuze ihambe ngendlela ehambisanayo futhi ebheke endizeni yombhalo ozothathwa izithombe.
Ukuqondaniswa kwekhamera nangemuva kwelensi maqondana nendiza yama-codices kubaluleke kakhulu, kanye nokugcina ukulinganisa nesilinganiso esifanayo emifanekisweni. Lokhu kufanele kwenziwe ngale ndlela, ngoba izithombe ezithwebula izithombe zamanye ama-codex, ezakhiwe ngendlela enkulu, zenziwa izingxenye ezithile, ukuze kutholakale isinqumo esiphezulu kakhulu.
Ama-codices yimibhalo enenani lamagugu omlando elidinga izindlela ezinzima kakhulu zokongiwa kwemvelo, yingakho izinga lokukhanyisa lenzelwe ukusiza ukugcina ukuzinza kwezinto eziphilayo zemibhalo eshiwo.
Ukusetshenziswa kwe-light-electronic light light kwavinjelwa ngenxa yokunotha kwayo ekukhishweni kwe-ultraviolet, futhi ukhetho lwenzelwe ukukhanya kwe-tungsten okungu-3 400 ° K. Isethi yamalambu wesithombe amane angama-250-watt afakwa izihlungi ze-glass diffuser ezifriziwe Izihlungi ze-Acetate polarizing ziqondaniswe nokugcina uhlelo lokukhanyisa oluhlukaniswe ngaphesheya. Isihlungi se-polarizing-analyzer naso safakwa kwilensi yekhamera ukuze ukuqondiswa kwemishayo ekhanyayo evela emalambini futhi kukhonjiswe yilo mbhalo "kuqondiswe kabusha" ngesihlungi se-analyzer, ngakho-ke ukungena kwabo kukhamera kube ikheli elilingana nalelo ababenalo ngenkathi benikezwa. Ngale ndlela bekukwazi ukulawula ukucabanga kanye nokwakheka, kanye nokwandisa umehluko ngokukhanyisa okufana, okusabalalisa nobungani bombhalo; okungukuthi, i-680 lux, i-320 engezansi kwe-lux eyi-1 000 evunyelwe ukuthwebula izinto zomnyuziyamu.
Impendulo ye-densitometric yezinhlobo ezine ze-emulsion yezithombe ezithwetshulwayo ibonakalisiwe: Ifilimu ye-Ektachrome 64 yohlobo T yamaslayidi ombala anezintambo ezingama-50 kuye kwezingu-125 / mm mm; Uhlobo lweVericolor II L ngemibala emibi ngemigqa eyi-10 kuya kwengu-80 / isisombululo semilimitha; I-T-max yeziphikiso zemigqa engama-63 kuye kwangama-200 / resolution ye-mm, nefilimu ye-infrared esinejubane elikhulu emnyama nomhlophe enesinqumo semigqa engama-32 kuye kwangama-80 / mm.
Izithombe ezibangelwe izivivinyo ezenziwa ekuqaleni kwephrojekthi zenziwa zafakwa ngekhompyutha ku-INAOE microdensitometer. Lezi zenzo beziyingxenye yesigaba somshayeli wesibili. Lezo ezitholwe kwifilimu engu-64 T ebonakalayo zenziwa zafakwa ngombala omnyama nomhlophe ngesisombululo sama-microns angama-50 ngephuzu ngalinye, okwanele ukubuyisa isithombe nezinye izinto zemidwebo ezingasabonwa ngamehlo enyama kwasekuqaleni. Ngalesi sinqumo futhi sinikezwe indawo yedijithali, ibhodi ngalinye lithatha isilinganiso sememori eyi-8 MB.
Lezi zithombe zirekhodwe, ku-hard disk yekhompyutha exhunywe ohlelweni lwe-microdensitometry; ngokuhamba kwesikhathi, zithunyelwa kwamanye amazwe (ngenethiwekhi) ziye endaweni yokusebenza ye-SUN ukuze zithunyelwe, bese zicutshungulwa esiteshini sokusebenzela i-Iraf, okuyi-manipulator yedatha yokuhlaziywa kwezithombe zezinkanyezi.
Izithombe zicutshungulwa ngama-pseudocoIorations amahle futhi amabi, futhi ngale ndlela ziyahlaziywa ukuze zibone umehluko owaziswa yilwazi ngokuya kwenhlanganisela yama-pseudocoIorations. Omunye wemiphumela ebaluleke kakhulu ukuthi ukutadishwa kwama-codices, ngokususelwa ezithombeni ezi-mbumbulu, akugcini nje ngokusivumela ukuthi sibone imininingwane ngokucacile ukwedlula kokumnyama nokumhlophe, kepha futhi kunxephezela ukonakala okuthile okutholwe yimibhalo - ngenxa yokuhamba kwesikhathi. isikhathi nezinye izinto noma izici zemvelo zombhalo, ezinjengokwakheka, imicu, imihuzuko, ukuhlukaniswa kokukhulelwa, njll.
Iqembu elenza imikhakha eyahlukene elenziwe ngabagcini bezimali, izazi-mlando, ababuyiseli bezithombe, ososayensi, onjiniyela be-elekthronikhi, odokotela bamehlo kanye nabasebenzi baselabhoratri, bonke abangabesikhungo sombuso, ababambe iqhaza kulo msebenzi, okuthi ngesivumelwano bahlanganise ngempumelelo ulwazi lwabo kanye nokuhlangenwe nakho kokulondolozwa kwamagugu amasiko eMexico.
Kuze kube manje, amakhodikhodi asekuqaleni ayishumi nantathu afakwe ekhompyutheni: Colombino, Boturini, Sigüenza, Tlatelolco, Azoyú II, Moctezuma, Mixteco Postcortesiano No. 36, Tlaxcala, Nahuatzen, San Juan Huatla, Partial Plan of Mexico City, Lienzo de Sevina neMapa ngu-Coatlinchan.
Izinketho zocwaningo ezinikezwa izithombe zedijithali ziningi. I-hypothesis yokubuyiselwa kwe-elektroniki kwezithombe ingenziwa, ngokwesibonelo, ukubuyisela amanani wezwi wesithombe ezingeni le-pixel (isithombe sesithombe), kanye nokwakhiwa kabusha kwemininingwane eyehlisiwe noma elahlekile, kulinganiswa amanani wethoni wamaphikseli angomakhelwane. kuleyo ndawo okukhulunywa ngayo.
Njengamanje, ukusetshenziswa kwezithombe ezidijithali kanye / noma ze-elekthronikhi kumaqoqo omlando kuvumela ukufinyelela okuthe xaxa eqoqweni, futhi kwandisa amandla omsebenzi wokulondoloza ngokuwafaka ezinhlelweni ezizenzakalelayo zereferensi kanye nemininingwane yekhathalogi. Ngokunjalo, ngemifanekiso edijithali, imibhalo ingakhiwa kabusha ngokusebenzisa ukucutshungulwa okufanele kwezithombe futhi yakhelwe ngokukhethekile ngabaphenyi abavela emikhakheni ehlukahlukene.
Okokugcina, izithombe zedijithali ziyithuluzi lokubonwa kwamakhophi eqoqo, angasetshenziswa emibhalweni yokongiwa kwemibhalo, ekuqapheni ukwelashwa kokubuyiselwa ngokomzimba nasekutholakaleni imibhalo eprintiwe ephepheni yemyuziyamu kanye / noma izihloko; ngokufanayo, ukubona ngeso kuyithuluzi lokukhombisa ukonakala okungenzeka imibhalo ingahlupheka ngokuhamba kwesikhathi.
Izithombe zedijithali nazo ziyithuluzi elinamandla lokuhlaziya kanye nemibhalo yamaqoqo wezithombe; kodwa-ke, ukwenziwa kwalezi zinqubo akumele kube yingozi emisebenzini yokongiwa kwemvelo eqinisekisa ukuvikeleka kwalawo maqoqo omlando.
