Tamura纹理特征的六个分量对应于心理学角度上纹理特征的六种属性，分别是粗糙度（coarseness）、对比度（contrast）、方向度（directionality）、 线像度（linelikeness）、规整度（regularity）和粗略度（roughness）。其中，前三个分量对于图像检索尤其重要。(The six components of the Tamura texture feature correspond to the six properties of the texture feature in the psychological perspective, namely, coarseness, contrast, directionality, linelikeness, and regularity. and roughness. Among them, the first three components are especially important for image retrieval.)
