Description:

PyAFBF 0.2.0

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. More details can be found on the documentation.

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).

Installation from sources
The package source can be downloaded from the repository.
The package can be installed through PYPI with

pip install PyAFBF

To install the package in a Google Collab environment, please type

!pip install imgaug==0.2.6
!pip install PyAFBF
