This paper focuses on the statistical comparison between the abundance and grain-size distribution of inclusions in pottery, determined by digital image process on images acquired using different methods (crossed-polarized light optical microscopy, back-scattered scanning electron microscopy (SEM) and microchemical mapping also under SEM). The results clearly indicate that the acquisition method deeply affects the absolute quantification, resulting in highly underestimated values for crossed-polarized light images with respect to those obtained from the microchemical mapping. Besides absolute quantification, the grain-size distribution shows some small differences among acquisition methods both in mean and variance values although frequency distributions and cumulative curves of inclusions show some similarities regardless of the acquisition method. Differences in terms of abundance and grain-size distribution of inclusions on the same sample are here analyzed and related to the limitations of each acquisition method.

通过数字图像处理对不同尺寸的图像采集方法进行粒度分析和陶瓷夹杂物定量的比较：结果有多相似？

本文着重于通过数字图像处理对使用不同方法（交叉偏振光光学显微镜，背散射扫描电子显微镜（SEM）和微化学法）获得的图像进行数字图像处理确定的陶瓷中夹杂物的丰度和粒度分布之间的统计比较。也在SEM下绘制地图）。结果清楚地表明，采集方法对绝对定量产生了深远的影响，相对于从微化学作图获得的结果，交叉偏振光图像的值被大大低估了。除了绝对量化之外 尽管频率分布和夹杂物的累积曲线显示出一些相似性，但无论采用哪种采集方法，晶粒尺寸分布在平均值和方差值方面均在采集方法之间存在一些细微差异。本文分析了同一样品上夹杂物的丰度和粒度分布方面的差异，并与每种采集方法的局限性有关。
