基于图像处理的黄瓜叶片病斑分级方法的研究

目前由于植物病理学中辨别病害主要以目测为主,主观判断占据主导。为了实现可靠的病害诊断,开发出一种基于计算机图像处理技术的病害分级新方法,并运用了分水岭法提取叶片区域。为了减少由光照变化产生的干扰,经比较提出了在YUV颜色模型下选取V分量进行病斑分割的方法。最后通过计算病斑面积与叶片面积的比例得出病害的染病级别。实验表明,该方法能够快速准确地对黄瓜叶片病害的严重程度进行分级,具备良好的分类能力。

Grading Method of Cucumber Leaf Spot Disease Based on Image Processing

At present,in the plant pathology distinguishes plant disease mainly to measure with the eye primarily,and judges the hold leadership subjectively.To realize the reliable plant disease diagnosis,the paper developed a new disease grading method based on computer image processing.The article has utilized the watershed law extraction leaf blade region;In order to reduce the disturbance which produced by the illumination change,with the comparison,this paper selected V component to carry on sickness spot divisi...
