Description of different texture features by gray level co-occurrence matrix (GLCM).

Textures	Description
Mean	The Mean is the average grayscale of all pixels for the image.
Variance	The Variance stands for the change of grayscale.
Homogeneity	The Homogeneity can measure the uniformity of local grayscale for one image. More uniform of the local grayscale means high value of Homogeneity.
Contrast	The Contrast stands for the clarity of texture. The higher the contrast value, the clearer the image.
Dissimilarity	The Dissimilarity mainly represents for the difference of grayscale.
Entropy	The Entropy is the measurement of the information for one image. No texture feature means Entropy value is 0.
Second Moment	The Second Moment reflects the uniformity degree of grayscale.
Correlation	The Correlation can measure the level of similarity in the row or column direction.
