一种基于变差函数的纹理图像分割方法

摘要

本文基于变差函数提出一种图像纹理分割的新方法。由于变差函数反映图像数据的随机性和结构性，因而能很好的表达纹理图像的特征。文中算法根据变差函数的这种性质将单步长变差函数值作为图像纹理特征进行分割，实验结果表明它对纹理图像分割与识别是十分有效的。%This paper proposes a novel algorithm for segmentation of texture image based on variogram function. Texture feature obtained by the function can characterize randomicity and structure of texture. The variogram value and the variable distance calculated by the variogram function are used for the segmentation of texture image. This method is proved to be feasible and effective by experiments.
