The Gray Level Difference Vector (GLDV)

[Artur Bercik]

Dear Stéfan

Thank you so much for your kind response to my question.

I have collected the following references about GLDV. It is mentioned that
GLDV is the the sum of the diagonals of the GLCM.

Look forward to finding GLDV on scikit-image.
