LuraWave JP2, LuraTech’s beta implementation of the up-coming JPEG2000 standard, is currently available for testing to developers. Software development kits for Windows 98/ME/NT/2000) and an Adobe Photoshop Plug-In (Win98/NT and Macintosh) are currently available.
JPEG2000 is a new image format standard recently being finalised by the ISO/IEC JTC1 SC29 Working Group 1, also known as the Joint Photographic Experts Group. The full version of JPEG2000 image standard is due for release on June 1, 2001. This group has verified the beta version of JPEG2000 which is being provided by LuraTech in software development kit form.
LuraWave JP2 allows software and hardware devices to compress and decompress lossless or lossy image data. The wavelet-based data coding enables imaging software, digital cameras, scanners, Internet browsers, mobile devices, and various hardware with small storage requirements to compress and decompress high-quality digital photographs without sacrificing image data.
JPEG2000 offers advantages over the original JPEG file format. With JPEG2000, large digital image files can be compressed to less than 2 percent of its original file size. The ability to perform lossless (no loss of image data) to lossy (discards a designated amount of image data) compression within the same mode is a key difference from the existing JPEG standard, which is lossy and therefore unsuitable for archiving digital images.
