How i can extract GLCM feature from 3d volumetric brain tumor image?

I need code to extract GLCM features and then classification this features by SVM.

The GLCM features can be is obtained by computing gray-level co-occurrence matrix using “graycomatrix”. Next, the “graycoprops” computes the properties such as Entropy, Homogeneity etc. by processing the matrix. Currently, “graycomatrix” function supports only 2-D intensity images as input. As a potential workaround, convert the 3-d image to the 2-d gray-level image using “im2gray” then extract the GLCM features. Refer the following documentation link to know more about GLCM properties.
