General: JPEG type quantization matrices for Wavelet Transforms

Hey Wavletters:

As promised at the San Diego SPIE conference, I have a reference to an
article where JPEG type of coding was done for images using wavelet based
methods (in this case for Wavelet Packets). This article is titled "JPEG-based
Image Compression Scheme Using Fully-decomposed Wavelet Packet (FWP) Transform"
by Kwo-Jyr Wong, Po-Yuen Cheng and C.-C. Jay Kuo found on pp. 75-86 of SPIE
proceedings vol 2186 - Image and Video Compression (1994).
They give a proposed JPEG type quantization matrix in the article, which
is very interesting and informative.
