This directory contains wavelet decompress image of grayscale "lena", 512x512x8. The middle number of the file name means compression ratio with respect to the original raw file size. So, the file size of compressed lena.3_32.gif will be 262144bytes / 3.32 ~= 78959byes. The 19.4 : 1 file is using the default setting with a time on compress/decompress sustained at 1.96 sec on a SSP2. The original is in file "lena.raw". Since my hand crafted "raw2gif" convertor is done rapidly, some gif viewer may complained. I am sorry. The original is left here so that people can make side by side comparison. and also MSE comparison. Please feedback comments to: willy@bucsf.bu.edu, Kin Hui. If someone our there can make a timing of the lena.raw on some other JPEG variance algorithm, please email me the results. Hopefully, this directory will start a USENET wide understand of the still image compression technology. Very much of the algorithms are too young and really need people to improve on. Thank you very much. And thanks MIT for the avalibity of "export.lcs.mit.edu". TNX 1.0E06. Kin, Hui. willy@bucsf.bu.edu May, 21, 1991.
