pgmtexture - calculate textural features on a PGM image
pgmtexture
[-d d]
[pgmfile]
This program is part of Netpbm(1).
pgmtexture reads a PGM image as input and calculates textural features based on spatial dependence matrices at 0, 45, 90, and 135 degrees for a distance d (default = 1).
Textural features include:

In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options
), pgmtexture recognizes the following
command line option:
The method for finding the Maximal Correlation Coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge.
