New Perspectives on Image Compression
Michael Thierschmann, Uwe Martin, Reinhard Rösel · 1997
Effective data compression techniques are necessary to deal with the increasing amount of data produced by modern image processes. The quality and features of the currently established image compression techniques, including the JPEG-standard, are not sufficient for an increasingly large number of applications. New image compression techniques based on wavelet-transformations offer a solution. These techniques allow the combination of lossless and lossy compression with extremely high compression rates and image quality. This paper discusses the principles of wavelet- and JPEG-compression and compares the new wavelet techniques with the JPEG-standard method. Additionally we present a software image compression package, LuraWave, which allows the use of wavelet image compression in a wide range of commercial applications.
