Abstract Background Several fractal and non-fractal parameters have been considered for the quantitative assessment of the vascular architecture using a variety of test specimens and of computational tools. The fractal parameters have the advantage of being scale invariant . to be independent of the magnification and resolution of the images to be investigated making easier the comparison among different .
