    "abstract": "In this work it is shown that vascular structures of the human retina\nrepresent geometrical multifractals, characterized by a hierarchy of exponents\nrather then a single fractal dimension. A number of retinal images from the\nSTARE database (www.parl.clemson.edu/stare) are analyzed, corresponding to both\nnormal and pathological states of the retina. In all studied cases a clearly\nmultifractal behavior is observed, where capacity dimension is always found to\nbe smaller then the information dimension, which is in turn always smaller then\nthe correlation dimension, all the three being significantly lower then the DLA\n(Diffusion Limited Aggregation) fractal dimension. We also observe a tendency\nof images corresponding to the pathological states of the retina to have lower\ngeneralized dimensions and a shifted spectrum range, in comparison with the\nnormal cases.",
