摘  要:
精准识别作物病害的前提是精确提取其特征。为此,利用计算机图像处理技术,研究了黄瓜霜霉病的特征提取过程。使用高精度的光学设备直接进行数字图像采集,再运用图像预处理方法对图像数据进行优化,去除干扰,精确定位病斑部位;分析黄瓜霜霉病的表现形式,从统计量、颜色和形状3个方面分离出特征参数值15个。这些特征值将作为识别该病害的主要依据,大大提高了病害的识别精度。

摘  要:
The precise of identification of crop diseases is to extract its characteristics accurately. The study used computer image- processing techniques,study on the characteristic extraction process of cucumber downy mildew. Directly using a high precision optical equipment for digital image acquisition,then use image preprocessing method for optimizing image data,removing interference,pinpoint lesion site. Analyzed the manifestations of cucumber downy mildew,15parameter values were got from statistics,color and shape. These values will serve as the main basis for identifying the disease,greatly improving the disease recognition accuracy.
