| 摘 要： | 文章介绍了一种基于叶片图像的形状特征对叶片进行识别的方法。首先对叶片图像进行预处理并且提取出叶片的轮廓,然后利用轮廓计算得到叶片的矩形度、圆形度、偏心率等8项几何特征和7个图像不变矩,同时在文中提出了一种新的移动中心超球分类器,利用其对得到的形状特征进行分类从而实现了对20多种植物叶片的快速识别,并且平均识别率达到了92%。

| Abstract: | This paper introduces a method of recognizing leaf images based on shape features.Firstly,we apply image pre-processing techniques to get the contours of the leaves.Then we extract eight geometric features including rectangularity,circularity,eccentricity,etc,and seven moment invariants from leaves' contours for classification.Finally we propose a new moving menter hypersphere classifier to address these shape features.As a result there are more than 20 kinds of plant leaves successfully recognized.The average correct recognition rate is up to 92 percent. |
