glcm_marginals {gtexture}

Marginal distributions of the GLCM

Description

Functions for the calculation of marginal distributions from the GLCM matrix.

The partial sum of the matrix is used to determine the distribution over the sum of neighbor pairs, returns a value for a given sum k.

The partial sum of the matrix is used to determine the distribution over the sum of neighbor pairs, returns a value for a given difference of k.

Usage

xplusy_k(glcm, k)

xminusy_k(glcm, k)

Arguments

glcm

square co-occurrence matrix

k

real integer (given difference)

Value

int or double (xplusy_k: sum of matrix entries with given index sum)

int or double (sum of matrix entries with given index difference)
