Abstract :
The performance of several reversible decorrelating transforms is evaluated in the JPEG-2000 baseline system. All of these transforms are based on tree-structured filter banks. Through the analysis of lossy and lossless compression results, a reversible version of the Cohen-Daubechies-Feauveau (2, 2) wavelet transform is found to perform best overall. A reversible version of a subband transform developed by Balasingham and Ramstad (see Proc. of 31st Asilomar Conference on Signals, Systems, and Computers, Monterey, CA, USA, 1997.) is also found to work particularly well for textured images
