摘要
运用计算机图像处理和分析技术对植物叶片图像进行图像预处理并提取叶片的轮廓,通过分析轮廓曲线中离散像素点的导数值,获取叶形的犄角点,从而提取锯齿,为基于叶片外观特征的植物分类提供辅助.
With computer-aided image processing and analyzing techniques, the experiments apply image pre-processing techniques to get the contours of the plant leaves. The authors analyze the derivative values of pixels in contour curve and then put up the method of obtaining the corners of leaf shape and extracting the features of leaf tooth. These methods will give great help for plant classification by leaf appearance features.
