We present a method for texture synthesis based on the simulation of a process of local nonlinear interaction, called reaction-diffusion, which has been proposed as a model of biological pattern formation. We extend traditional reaction-diffusion systems by allowing anisotropic and spatially non-uniform diffusion, as well as multiple competing directions of diffusion. We adapt reaction-diffusion system to the needs of computer graphics by presenting a method to synthesize patterns which… Expand

TLDR
The generalized reaction-diffusion textures display spatial inhomogeneity, even when the diffusion process is homogeneous, making it possible to generate complex textures from few parameters when compared with previous techniques employing inhomogeneous reaction-Diffusion. Expand
Advanced Reaction-Diffusion Models for Texture Synthesis
TLDR
Techniques that help overcome the difficult parameter selection process that controls the pattern development are presented and it is shown that it is possible to create multiple and oscillating patterns by coupling two reaction-diffusion systems together. Expand

TLDR
A biologically motivated method of texture synthesis called reaction-diffusion is described and it is demonstrated how these textures can be generated in a manner that directly matches the geometry of a given surface. Expand
Texture synthesis using reaction-diffusion systems and genetic evolution
TLDR
This research uses a genetic algorithm to explore the parameter spaces of reaction-diffusion systems, using input from a human participant as the fitness function to guide the evolution. Expand
Sketching reaction-diffusion texture
TLDR
An interactive interface for sketching synthesized textures that allows a user to sketch a pattern of spots or stripes with arbitrary orientations, and then automatically generates a pattern with the same attributes as the sketch, and it is shown that this procedure can be applied to realistic 3D surfaces.

A texture synthesis method for liquid animations
TLDR
This paper achieves temporal coherence by initializing the surface texture with color values advected from the surface at the previous frame and including these colors in the energy function used during optimization. Expand
Visual simulation of texture/non-texture image synthesis
TLDR
A new and effective image modeling dual technique which is capable of simulating both texture image synthesis and non-texture images like fractals and an investigation of the relationships between the generated patterns and their corresponding graph grammars is discussed. Expand
Texture synthesis by L-systems
We present a method for texture synthesis based on the extended L-systems, called TSL-systems, which are defined as a combination of parametric, stochastic and MAP L-systems. A description ofExpand

Applications of reaction-diffusion equations to image processing
TLDR
The authors briefly outline reasoning which led to the adoption of RD-systems as an image processing paradigm, thus placing this approach into the current arena of image processing techniques. Expand
Sequential synthesis of natural textures
TLDR
This method allows us to synthesize gray tone texture fields while “controlling” their second-order statistics in rather large neighborhoods, and seems to strongly support the conjecture that the visual system is only sensitive to the second- order spatial averages of a given texture field, so that these statistics should be used to model textures.

A Pre-pattern formation mechanism for animal coat markings
TLDR
It is proposed that a reaction-diffusion system which can be diffusively driven unstable could be responsible for the laying down of the pre-pattern for animal coat markings and shows that the geometry and scale of the domain, the relevant part of the integument, during the time of laying down plays a crucial role in the structural patterns which result.

The Chemical Basis of Morphogenesis

A possible mechanism by which the genes of a zygote may determine the anatomical structure of the resulting organism is discussed, suggesting that certain well-known physical laws are sufficient to account for many of the facts. Expand

TLDR
Analysis of a spotted zebra in the light of the model provides evidence that zebra stripes arise from the inhibition rather than the stimulation of melanin; their pattern is thus of white stripes on a black background. Expand
