Dear scikit-image Users:


It is so nice to find The Gray Level Co-occurrence Matrix (GLCM) in scikit-image.
http://scikit-image.org/docs/dev/auto_examples/plot_glcm.html

However, I am interested in using The Gray Level Difference Vector (GLDV).
Is not it available in scikit-image?
Can someone guide me how to calculate it?


Thanks in the advance.
