Is there any opinion about how can calculate these kind of texture's regularity metric. You see there is difference because of directionality,particle shape, size, placement etc. Is there any code for this. regards

Try functions like stdfilt(), graycomatrix(), graycoprops(), regionprops(), etc. There are a lot of things you could potentially measure so the algorithm depends on exactly what you're interested in characterizing.

If you use regionprops() you can get the centroid of all the blobs. Then you can use pdist2() in the stats toolbox to find the distance of every centroid to every other centroid. Sometimes people look at the mean distance of the 5 or 10 closest blobs.

How can we use GLCM features to obtain fractal dimension?

You're calling pdist2() incorrectly. You have to pass it two arrays of x,y coordinates. In your case they will be the same array. So you should do
distances = pdist2(centroids, centroids, 'euclidean');

This is not an answer to the original question. Was it a comment to me, or a comment on your other "answer"?
