摘　　要：为了实现植物病害的智能化诊断,本文以温室植物的侵染性病害为对象,以matlab和VC++语言为开发工具,选取了温室黄瓜栽培中常见的霜霉病和炭疽病2种病害图像为切入点进行图像增强处理研究。通过对比灰度变换增强、空域滤波增强和频域滤波增强3种技术,发现了快速中值滤波是应用于植物病害图像上效率最高、效果最明显的1种增强方法。In order to realize the intelligentizing of prevention and control for greenhouse plant diseases, it is this study that takes greenhouse plant infectious diseases as research object, with taking the language of Madab and VC ＋ ＋ as development tool, by selecting the two kind of familiar cucumber disease as downy mildew and anthracnose as the cut - in point in the study. By testing gray transform enhancement .spatial filtering enhancement and frequency domain filtering enhancement, it is the fast median filtering in spatial filtering enhancement that is fund as one of the enhancement methods with the best effect and efficiency in digital image processing for cucumber diseases of greenhouse.
