Are textures natural?

We make the simple observation that, because of global symmetry violating higher-dimension operators expected to be induced by Planck-scale physics, textures are generically much too short-lived to be of use for large-scale structure formation. The texture scenario for large-scale structure formation is an attractive alternative to inflation or other, defect mediated, proposals based on new phy...

Statistics of Natural Stochastic Textures ∗

Statistics of natural images have become an important subject of research in recent years. The highly kurtotic, non-Gaussian, statistics known to be characteristic of many natural images are exploited in various image processing tasks. We focus on Natural Stochastic Textures (NST), an important subset of natural images. In the first part of this report, we show their abundance in natural images...

Synthesis of Near-regular Natural Textures

Texture synthesis is widely used in the field of computer graphics, vision, and image processing. In the present paper, a texture synthesis algorithm is proposed for near-regular natural textures with the help of a representative periodic pattern extracted from the input textures using distance matching function. Local texture statistics is then analyzed against global texture statistics for no...

Exploring Transition Textures for Pseudo-natural Maps

Pseudo-natural maps show land cover information in a compelling style that combines cartographic abstraction with natural appearance. To make this style available to the modern cartographer, a (semi-) automatic method that generates pseudo-natural textures for rendering land cover categories on maps would be helpful. This article focuses on a single aspect of pseudo-natural map creation, namely...
