Hello,
You might want to look into the r.le Programs. A set of GRASS programs for the
quantitative analysis of landscape structure
(http://blue.lakeheadu.ca/grass/gdp/terrain/r_le_22.html).
r.le calculates IDM (inverse difference moment) and entropy, and GRASS can
import Idrisi images.
I'm not sure if it applies but there is an app called "Digital Filter" that
allows for spatial and frequency domain filtering of Idrisi image files.
Hope this helps,
Justin

Subject: Haralick parameters
--- Start of Idrisi List message
Hullo,
I was wondering if out there somebody has a program which runs under
DOS/Win3.X/Win95 and is able to calculate some Haralick textural
parameters from images in Idrisi-friendly format. The parameters I'm
mostly interested into are IDM (inverse difference moment) and entropy.
BTW, I assume that these parameters and other co-occurence matrix based
textural parameters will not be included in the new release of Idrisi.
Can anyone confirm or deny that?
Cheers,
Marco
