JPEG 2000 Examples from the Library of Congress Music Division

Listed below are images from offered by the Library of Congress Music Division for experimentation. Included are both lossless compression and lossy compression J2K versions of the sample images, with perhaps another variation in having the images sharpened using NIK-Sharpen Pro. The TIFFs are also available to show folks just what a pain it would be do deal with the originals.

The first collection of images comes from the Federal Theatre Project. These images were captured at a high resolution because the source materials were literally disintegrating, and a very good copy was needed. The "LC j2k FedTheatreProj test.pdf" file outlines why digital and JPEG 2000 was the best way to go.

The other collection, Johannes de Musica, was a musical work that benefits from close examination of the item's construction. The public version of this document is available through the Library of Congress American Memory project. See the "LC j2k JohannesDeMusica Test.pdf" file for details.
