glcm_metrics: Calculates the GLCM Texture Metrics from a GLCM

Description

Calculates the GLCM Texture Metrics from a GLCM

Usage

glcm_metrics(
  GLCM,
  metrics = c("glcm_contrast", "glcm_dissimilarity", "glcm_homogeneity", "glcm_ASM",
    "glcm_entropy", "glcm_mean", "glcm_variance", "glcm_correlation"),
  average = FALSE
)

Value

GLCM based texture measures as a numeric vector.

Arguments

GLCM

A numeric matrix or list of matrices representing a Normalized GLCM.

metrics

A vector of texture metrics to return. Valid entries include "glcm_contrast", "glcm_dissimilarity", "glcm_homogeneity", "glcm_ASM", "glcm_entropy", "glcm_mean", "glcm_variance", "glcm_correlation".

average

Logical indicating whether to average metrics across the supplied GLCMs
