显微图象的计算机粒度分析

本文权述了一个人机交互式的显微图象计算机粒度分析系统.该系统软件的设计充分考虑了显微图象对比度差、照度不均匀、信噪比小等特点,并且设计了专门的算法以处理颗粒图象中的空洞以及相互重叠的问题。该系统可以用于分析不同放大倍数和不同物质的显微图象或用其它手段所获得的图象.分析结果以分布曲线和数字的形式输出.内容可包括:颗粒面积、长轴、短轴、长短轴之比的统计分布以及上述各项分布的期望值和方差.

Computer Analysis of Particles in Microscopic Images

This paper presents a computer analysis system for particles in micro-scopic images.Cares has been taken in the designing of the system in orderto take into full account of poor qualities of microscopic images,such as lowcontrast,non-uniformity of illumination,low signal-to-noise ratio,etc..Spe-cial algorithms developed to deal with holes witnin particles and overlappedparticles.The system can be used for analyzing microscopic images of dif-ferent magnification factors and for analyzing images obtained by means otherthan microscopy.The contents of analysis results includes particle area,longaxis,short axis,ratio of long axis and short axis.These results are qiven inthe forms of mean,deviation and distribution curves.
