| 摘 要： | 本文基于空间统计学提出了新的纹理周期性和相似性度量。实验表明,用纹理的周期值、周期性成分所占比例、周期性成分所占比例的变化率以及周期复杂度等多个参数可以提供较多的纹理周期性信息。虽然对周期性纹理分析,室穴模型是一个合适的选择,但该模型的实际拟合还存在一些困难。

| Abstract: | This paper proposed a new model for measuring the texture periodicity and similarity based on the variogram of geostatistics.Conventional texture periodicity can be described by a single period value,which represents the size of textural primitives.However,it is not enough for analyzing textures with the same size of textural primitives.This paper gives more parameters to describe the texture periodicity: a period value,a periodicity component content,a variability of the periodicity component content and a complexity value.All four parameters are calculated from the variogram of a certain direction.Several directions can be combined to provide more information about both periodicity and its direction.The periodicity component is defined as the ratio of the swing with the variogram maximum.The variability of the periodicity component content is defined as the variability of the above value per period.The complexity value is referred to the count of extremum in a period of variogram.From these parameters the authors give a new similarity between the periodic textures.The experiments show that the proposed method can describe texture periodicity in an effective way. |
