FADGI is the Federal Agencies Digitization Guidelines Initiative: http://www.digitizationguidelines.gov/ The technical guideline has a number of sound suggestions: http://www.digitizationguidelines.gov/guidelines/digitize-technical.html (it also links dozens of English Wikipedia articles). The verification software is available for free (only for Windows): http://www.digitizationguidelines.gov/guidelines/digitize-OpenDice.html (Kakadu is not free software, sadly.) Nemo -------- Messaggio inoltrato -------- Oggetto: Using Kakadu JPEG2000 Compression to Meet FADGI Standards Data: Mon, 31 Jul 2017 21:00:46 +0000 Mittente: jeff kaplan <http://blog.archive.org/2017/07/31/using-kakadu-jpeg2000-compression-to-meet-fadgi-standards/> Using Kakadu JPEG2000 Compression to Meet FADGI Standards The Internet Archive is grateful to the folks at Kakadu Software for contributing to Universal Access to Knowledge by providing the world’s leading implementation of the JPEG2000 standard, used in the Archive’s image processing systems. Here at the Archive, we digitize over a thousand books a day. JPEG2000, an image coding system that uses compression techniques based on wavelet technology, is a preferred file format for storing these images efficiently, while also providing advantages for presentation quality and metadata richness. The Library of Congress has documented its adoption of the JPEG2000 file format for a number of digitization projects, including its text collections on archive.org <https://archive.org>. Recently we started using their SDK to apply some color corrections to the images coming from our cameras. This has helped us achieve FADGI standards in our work with the Library of Congress. Thank you, Kakadu, for helping make it possible for millions of books to be digitized, stored, and made available with high quality on archive.org <https://archive.org>!
