Fig. 1 144 of the wood texture samples that form the basis for this work

The examined wood textures present a huge variety of colours, from bright yellow over fiery red and royal purple to coffee brown. They distinguish from each other in an enormous richness of patterns and structures, like fiddle back flames, burls, birds’ eyes, quilts, masur and curly waves. At the same time, they share many common features. They all have regions of different densities, denser darker areas and less dense brighter areas. The textures are neither completely random (noise) nor deterministic (grid) but somewhere in between (stochastic). The periodicity of the occurrence of annual rings makes it an ideal topic for investigation with the presented process.
