Lacunarity can work as a supplement for describing texture of self-similar objects. We propose a systematic study of this measure based on a set of carefully designed prototype structures, providing also a comparision to already existing measures (generalized fractal dimension). We also illustrate its applications to material science (describing changes in polymer surface during gold dispersion) and cellular biology (describing stains in cancer cells from two cell lines in two conditions). To measure lacunarity the gliding box method was used.
