            **What it does**

            Image granularity is a texture measurement that tries to fit a series of structure elements of increasing size into the texture of the image and outputs a spectrum of measures based on how well they fit. Granularity is measured as described by Ilya Ravkin (in the paper *Bit representation techniques and image processing*). The size of the starting structure element as well as the range of the spectrum is given as input.
