Paleontologists often examine microscopic scratches and pits that form on teeth for indications of the diets of past animals. Most researchers count and measure scratches and pits from photomicrographs to identify microwear patterns for comparison among samples. This paper describes an affordable, available semiautomated image analysis procedure for microwear quantification. An image is downloaded from a scanning electron microscope frame buffer to a microcomputer, and the user identifies microwear features with a mouse-driven pointer. Microwear feature density, dimensions, and orientations are then computed and stored as ASCII files for subsequent data analysis.
古生物学家经常检查牙齿上形成的微观划痕和凹坑,以了解过去动物的饮食情况。大多数研究人员通过显微照片来计数和测量划痕及凹坑,以识别微磨损模式,从而对样本进行比较。本文介绍了一种经济实惠且可行的半自动图像分析程序,用于微磨损量化。图像从扫描电子显微镜帧缓冲器下载到微型计算机,用户通过鼠标驱动的指针识别微磨损特征。然后计算微磨损特征的密度、尺寸和方向,并将其存储为ASCII文件,以供后续数据分析使用。
