This paper will research how to separate plants (crop and weed) from complex roil background by applying machine vision technology, which is a prepared work for identifying weeds.

为此，就如何利用机器视觉技术从复杂的土壤背景下分离出植物(作物和杂草)的方法进行研究，从而为杂草的识别做前期准备工作。

On the field of agriculture and plant protection, weed identification technology in machine vision research at home and abroad has made part of the results.

在农业植保领域中，杂草识别在机器视觉技术的研究国内外已经取得了部分成果，绝大多数研究都集中在杂草植株的个体上。

Because it is a new research filed to apply computer vision for weed-sensing, there are not mature theories to support the weed-sensing technology.

计算机视觉技术用于杂草识别是一个相当新的研究应用领域，目前理论和技术尚不成熟。
