This paper introduces a method for modeling mosaic-like textures using a multispectral parametric Bidirectional
Texture Function (BTF) compound Markov random field model (CMRF). The primary purpose of our synthetic
texture approach is to reproduce, compress, and enlarge a given measured texture image so that ideally both
natural and synthetic texture will be visually indiscernible, but the model can be easily applied for BFT material
editing. The CMRF model consist of several sub-models each having different characteristics along with an
underlying structure model which controls transitions between these sub models. The proposed model uses the
Potts random field for distributing local texture models in the form of analytically solvable wide-sense BTF
Markovian representation for single regions among the fields of a mosaic approximated by the Voronoi diagram.
The control field of the BTF-CMRF is generated by the Potts random field model build on top of the adjacency
graph of a measured mosaic. The compound random field synthesis combines the modified fast Swendsen-
Wang Markov Chain Monte Carlo sampling of the hierarchical Potts MRF part with the fast and analytical
synthesis of single regional BTF MRFs. The local texture regions (not necessarily continuous) are represented
by an analytical BTF model which consists of single factors modeled by the adaptive 3D causal auto-regressive
(3DCAR) random field model which can be analytically estimated as well as synthesized. The visual quality
of the resulting complex synthetic textures generally surpasses the outputs of the previously published simpler
non-compound BTF-MRF models.
