calculate textural features on a PGM image

Examples (TL;DR)

Synopsis

pgmtexture

[-d d]

[pgmfile]

Description

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:

Algorithm taken from: Haralick, R.M., K. Shanmugam, and I. Dinstein. 1973. Textural features for image classification. IEEE Transactions on Systems, Man, and Cybertinetics, SMC-3(6):610-621.
   

Options

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:

-d distance

The distance.  Default is 1.

Limitations

The method for finding the Maximal Correlation Coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge.
