Morphological Features of Mathematical and Real-World Fractals: A Survey

  • Miguel Patiño-Ortiz,
  • Julián Patiño-Ortiz,
  • Miguel Ángel Martínez-Cruz,
  • Fernando René Esquivel-Patiño and
  • Alexander S. Balankin

The aim of this review paper is to survey the fractal morphology of scale-invariant patterns. We are particularly focusing on the scale and conformal invariance, as well as on the fractal non-uniformity (multifractality), inhomogeneity (lacunarity),...
