\toprule
Contrast 	& Contrast is measured by the sum of GLCM probabilities, weighted according to their distance from the diagonal point of the GLCM (the further the distance from the diagonal, the higher the contrast).\\ \midrule
Angular Second Moment &	Calculated from the sum of squared probabilities, high values provides a measure of the ``orderliness'' of the texture since high probabilities (definite patterns) will be emphasised, and low probabilities will be minimised.\\ \midrule
Entropy 	& Gives an indication of the ``disorderliness'' of the image by summing the natural log of each probability, which gives highest weight to low probabilities.\\ \bottomrule
GLCM Mean & Measures the average probability of whatever relationship the GLCM is measuring. Horizontal and vertical GLCMs may produce different means.
GLCM Variance & Measures the Standard Deviation of GLCM probabilities and is similar to the entropy measure. A completely uniform image will have a GLCM variance of zero.
