<br><font size=2 face="sans-serif">I don't mean to be dismissive of this
report, but I was hoping for something more definitive to prove that 'lossless'
JPEG compressions did indeed protect the integrity of the data.. </font>
<br>
<br><font size=2 face="sans-serif">Perhaps its just my ignorance, but I
was hoping for something along the lines of:</font>
<br>
<br><font size=2 face="sans-serif">- a study of a range of typical spatial
'imagery'.</font>
<br>
<br><font size=2 face="sans-serif">- evaluation of all spectral values
for each pixel in each image before compression.</font>
<br>
<br><font size=2 face="sans-serif">- 'lossless' compression of the
images</font>
<br>
<br><font size=2 face="sans-serif">- restoration of the compressed images</font>
<br>
<br><font size=2 face="sans-serif">- comparison of all spectral values
for each pixel in each restored image against the original pre-compressed
values.</font>
<br>
<br><font size=2 face="sans-serif">- definitive statement with reference
to the study results.</font>
