WebThe GLCM is a measure of the probability of occurrence of two grey levels separated by a given distance in a given direction. The features can be categorized into three groups, i.e. contrast group, orderliness group and statistics group. Contrast Group Features: Contrast Dissimilarity (DIS) Homogeneity (HOM) Orderliness Group Features: WebN is the number of gray levels, Pd is the normalized symmetric GLCM dimension, Pd(i, j) is GLCM value on element (i, j).
