Colecție impresionantă de 12 milioane de imagini vechi sau istorice, dintre anii 1500-1922

Nu este o comoară din aur sau argint, dar este cu siguranță o comoară a documentării istorice in imagini: un academician american va crea o bază de date formata din 12 de milioane de imagini istorice, care pot fi reutilizate in mod gratuit. Kalev Leetaru a încărcat deja 2,6 milioane de imagini pe Flickr, intre care se pot efectua si cautări, datorita tag-urilor adăugate automat, iar restul de imagini vor fi adaugate până anul viitor.


Fotografiile și desenele sunt obținute din peste 600 de milioane de cărți din diverse biblioteci, fiind de către organizația Internet Archive.

Accesul la aceste imagini era extrem de dificil, pana la punerea in practica a acestui extraordinar proiect. Kalev Leetaru a declarat proiectul de digitalizare s-a concentrat până acum pe cuvinte și imagini necunoscute.

"Majoritatea bibliotecilor importante si-au digitizat cărțile detinute, dar acestea erau puse la dispozitie ca PDF-uri sau lucrări ce puteau fi cautate ca text. Ei s-au concentrat pe cărți ca o colecție de cuvinte. Actiunea noastra inverseaza fenomenul, concentrandu-se pe imagini. Cele mai multe dintre imaginile din cărțile scanate nu sunt în nici una din galeriile de arta din lume, fiindca originalele sau pierdut cu mult timp în urmă. Întinzându-se pe durata a 500 de ani, biblioteca de imagini arata modul în care lumea s-a schimbat.", a declarat acesta.

Imaginile sunt dintre anii 1500-1922, fiindcă restricțiile privind drepturile de autor s-au anulat pentru aceasta perioada.

Internet Archive a folosit o recunoaștere optică a caracterelor (OCR), program ce analizeaza fiecare din 600 de milioane de pagini scanate, in scopul de a converti fiecare cuvant din imagine în text de căutat. Software-ul a adaugat de asemenea ca legenda, pentru fiecare imagine, și textul din paragrafele imediat precedente și următoare din carte.

Colecția de imagini vechi sau istorice o găsiti dând click AICI.
