算子标度高斯场的显式构造

Explicit constructions of operator scaling Gaussian fields

Marianne Clausel--Lesourd, Béatrice Vedel

摘要:

本文提出了一种显式的方法来生成一大类算子标度高斯随机场(OSGRF)。这种场是自相似场的各向异性推广。更具体地说,我们能够构造任何高斯场属于这个类与给定的赫斯特指数和指数。我们的建设提供了-模拟纹理以及检测图像中的各向异性-一大类模型与控制各向异性的几何形状和结构。

英文摘要:

We propose an explicit way to generate a large class of Operator scaling Gaussian random fields (OSGRF). Such fields are anisotropic generalizations of selfsimilar fields. More specifically, we are able to construct any Gaussian field belonging to this class with given Hurst index and exponent. Our construction provides - for simulations of texture as well as for detection of anisotropies in an image - a large class of models with controlled anisotropic geometries and structures.
