本文介绍了一个机器视觉系统，设计用于计算种子萌发胚根尖的数量，在控制光照，温度和湿度条件下。自动采集系统采用一种算法，该算法以完全无监督的方式分两步工作。第一步包括一个分类过程，它可以将彩色图像转换为二进制图像（种子为白色，背景为黑色）。在第二步中，对发芽的种子进行计数，提供平均发芽时间（MGT）。通过比较系统提供的结果与专家技术人员对向日葵种子的评价结果，验证了该方法。(C)2004 Elsevier B.V.保留所有权利。
This paper presents a machine vision system designed to count the number of emergent radicle tips on seedlots, under controlled lighting, temperature and hygrometric conditions. The automated acquisition system employs an algorithm which works in two steps, in a totally unsupervised way. The first step consists of a classification procedure which makes it possible to transform colour images to binary images (seeds in white, background in black). In the second step, counting of the germinated seeds is performed, providing the mean germination time (MGT). The method was validated by comparing the results supplied by the system to those evaluated by expert technicians, on sets of sunflower seeds. (C) 2004 Elsevier B.V. All rights reserved.
