[求助] 图像纹理特征的粗糙度和粒度这两个说法的关系???

图像纹理特征的粗糙度和粒度这两个说法什么联系?请各位前辈指教,万分感谢
附英文原文一段
A universal definition of texture is difficult to find due to the diversity of patterns in natural and artificial textures. Ac-cording to [20], textures are complex visual patterns composed of entities or subpatterns with characteristic brightness, color, slope, size, and scale. These properties give rise to the perceived lightness, uniformity, coarseness, smoothness, and granularity of the image texture as a whole.

就是其中的“granularity”,中文中很多说粗糙度,有些搞不清

Image granularity is a texture measurement that tries a series of structure elements of increasing size and outputs a spectrum of measures of how well these structure elements fit in the texture of the image. Granularity is measured as described by Ilya Ravkin (references below).
