Texture Parameters Extracted in the Analysis of CBCT scans.

Texture parameter	Description
Contrast	Represents the amount of local variation of gray level
Inverse difference moment	Homogeneity of the distribution of gray level on the image
Angular second moment	Measurement of image uniformity
Correlation	Linear measure dependence of gray level between neighboring pixels
Sum of squares	Measurement of the dispersion (related to average) of gray level distribution
Entropy	Degree of disorder between pixels in the image
Sum of average	Mean of the distribution of the sum of gray level
Sum of variance	Dispersion around the mean of the sum distribution of gray level
Sum of entropy	Disorganization of the sum distribution of gray level
Difference of variance	Dispersion of the gray level difference
Difference of entropy	Disorganization of the gray level difference
