There is difference between the number shown here and other previous results, for example, Hara'san work:
{{{
> 40" SLOT
> DPCM 2.36
> JPEG98 2.70
> JPEG95 3.47
> JPEG92 4.22
> JPEG90 4.63
> JPEG85 5.74
> JPEG75 7.63
> JPEG65 9.43
> JPEG50 12.0
> For 10s exposure time. }}}
!As I mentioned above, this is a preliminary study on EIS compression factor. The method and results shown here need to check, confirm and compare with other number. There are still mystery hide behind these numbers. It is really just a start, so more contributions are very welcome!
