PyAFBF: a Python library for sampling image textures from the anisotropic fractional Brownian field.

Abstract

The Python library PyAFBF is devoted to the simulation of anisotropic textures of image. These textures are sampled from a mathematical model called the anisotropic fractional Brownian field (AFBF) (Bonami & Estrade, 2003); see Figure 1 for an illustration. The library offers several features. Users can generate a wide variety of textures by setting the simulated model manually or randomly either manually or randomly. It also includes tools to compute model features (regularity, anisotropy,…) which may serve as attributes to describe generated textures. The library further offers the possibility to sample heterogeneous textures from random field models related to the AFBF.
