Dear Gamal

There are many single measurements to characterise the information of the co-occurrence matrix, and perhaps more precisely, the information difference between two different textures as assessed by the co-occurrence matrices of each texture. Some years ago I published a measurement (actually a measurement space) exactly for the assessment of textures called "The Bhattacharyya Space". Check my publications here in research gate, I recommend two,

A guide to co-occurrence matrix analysis,

The Bhattacharyya space for feature selection and its application to texture segmentation

I hope these will help. If you have questions, feel free to ask.

Regards,

Carlos
