通过借助Photoshop软件来分析正常区域与病变区域的RGB值,用Matlab软件将黄瓜叶片的照片转化为RGB的像素值矩阵,利用得到的各种界限和像素矩阵的值计算已经分级叶片的病斑区域与这个叶片总面积的比值,确定此方案下的病变程度范围,将其定为判断叶片病变程度的标准,最后用已经得到的标准去衡量待评叶片,并确定其病变级别,从而根据病斑区域与这个叶片总面积的比值来衡量病变程度。 Through the use of Photoshop software to analyze the normal region and the lesion area RGB values, with the Matlab software cucumber leaf photos into RGB pixel value matrix, the use of the various boundaries and pixel matrix values ​​obtained have been classified leaf lesion area And the ratio of the total leaf area to determine the scope of the lesion under this program will be set to determine the extent of leaf lesions standards Finally, the standard has been used to measure to be evaluated leaves, and determine the level of lesions, which lesions Area and the ratio of the total area of ​​the leaves to measure the degree of lesion.
