dissimilarity.matrix {gtexture}

Dissimilarity of a co-occurrence matrix

Description

Dissimilarity is the weighted sum of all of the absolute differences in the gray-levels assigned to neighboring nodes across the network or graph. For example, a diagonal matrix would represent only identical neighbors and no dissimilarity.

Usage

dissimilarity.matrix(glcm)

Arguments

glcm

gray-level co-occurrence matrix

Value

int or double (the weighted sum of differences)

Examples

# Calculate dissimilarity of a 2x2 uniform matrix
dissimilarity.matrix(matrix(1,2,2))

# Calculate dissimilarity of a diagonal matrix
dissimilarity.matrix(diag(1,5,5))

# Calculate dissimilarity of a sequential matrix
dissimilarity.matrix(matrix(1:16,4,4))
