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 …
