论文摘要
我们提出了一个基于CURVELET的模型,用于生成各向异性分数Brownian领域,该模型适用于具有方向依赖性自相似特性的模型。综合过程包括在Curvelet空间中产生系数,并具有零均值的高斯分布。这种方法允许在某种程度上表示具有随机行为的自然系统,并遵守给定的角度相关性分布。在异质地质结构,各向异性材料和复杂无序培养基中发现了此类系统的例子。
We propose a curvelet-based model for the generation of Anisotropic Fractional Brownian Fields, that are suited to model systems with orientation-dependent self-similar properties. The synthesis procedure consists of generating coefficients in the curvelet space with zero-mean Gaussian distribution. This approach allows the representation of natural systems having stochastic behavior in some degree and also obeying to a given angular distribution of correlations. Examples of such systems are found in heterogeneous geological structures, in anisotropic materials and in complex disordered media.
