Six ways to decode a lossy JP2

Some time ago Will Palmer, Peter May and Peter Cliff of the British Library published a really interesting paper that investigated three different JPEG 2000 codecs, and their effects on image quality in response to lossy compression. Most remarkably, their analysis revealed differences not only in the way these codecs encode (compress) an image, but […]

How does lossy JP2 image compression influence OCR?

Many institutions have been doing large scale digitisation projects during the last decade, and the question how to store the digital master images in a cost effective way made the JPEG2000 image format more popular in the library, museums, and archives community. Especially the lossy JP2 encoding of page image masters turned out to provide […]
