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. http://www.fp.ucalgary.ca/mhallbey/gldv.htm http://www.matdat.life.ku.dk/ia/sessions/session8-4up.pdf https://workspace.imperial.ac.uk/imagingfacility/public/DefiniensReferenceBo... Look forward to finding GLDV on scikit-image. Artur On Tue, Oct 28, 2014 at 11:46 PM, Stefan van der Walt <stefan@sun.ac.za> wrote:

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
There was quite a bit of discussion around this functionality.
https://github.com/scikit-image/scikit-image/issues/863 https://github.com/scikit-image/scikit-image/pull/914 https://github.com/scikit-image/scikit-image/pull/935 https://github.com/scikit-image/scikit-image/issues/899
One of the suggestions was that we rather specify offset than angle + distance. Since you are currently using the API, what is your feeling around that?
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?
I'd be happy to help you implement GLDV computation, if you want. Do you have a good reference at hand?
