Welcome to PyAFBF’s documentation!

The Package PyAFBF is intended for the simulation of rough anisotropic image textures. Textures are sampled from a mathematical model called the anisotropic fractional Brownian field. Some texture examples are shown below on the patchwork.



The anisotropic fractional Brownian field was introduced in [1] and further studied in several works [2, 3, 4, 5, 6, 7, 8]. It was applied for the modeling and the analysis of medical images [4, 5, 7, 9, 10] or photographic films [3] . The simulation method was designed in [11].

Package features

  • Simulation of rough anisotropic textures,

  • Computation of field features (semi-variogram, regularity, anisotropy indices) that can serve as texture attributes,

  • Random definition of simulated fields,

  • Extensions to related fields (deformed fields, intrinsic fields, heterogeneous fields, binary patterns).
