Method graycomatrix returns a glcm and a sclaed version of input image. I was just wondering how to scale the image to 8 gray scales. Also, I want some clarity on Energy obtained from this glcm. Energy needs to have values between 0 and 1 where 1 represents that the image is constant. So, can I say that Energy value closed to 0 is desired and this represents high energy ??
Please help

The ‘NumLevels’ property in ‘graycomatrix’ function scales the image to 8 gray scales as the default value of ‘NumLevels’ is 8. The maximum value of energy is ‘1’ which is obtained for a constant image.
