出一种基于多特征降维的植物叶片识别方法。首先通过数字图像处理技术对植物叶片彩色样本图像进行预处理,获得去除颜色、虫洞、 叶柄和背景的叶片二值图像、灰度图像和纹理图像。然后对二值图像提取几何特征和结构特征,对灰度图像提取 Hu不变矩特征、灰 度共生矩阵特征、局部二值模式特征和 Gabor 特征,对纹理图像提取分形维数,共得到 2183 维特征参数。再采用主成分分析与线性 评判分析相结合的方法对叶片多特征进行特征降维,将叶片高维特征数据降到低维空间。使用降维后的训练样本特征数据对支持向量 机分类器进行训练(plant species identification method is mainly based on blade automatic identification of low dimensional characteristics.However, can not fully describe blade low-dimensional feature information, identification accuracy is low, in this paper
A kind of plant leaves recognition method based on multiple feature dimension reduction.First by digital image processing technology to the plant leaf color sample image preprocessing, obtain background color removal, wormhole, petioles, and the blades of a binary image, gray image and texture image.Then the binary image to extract the geometric characteristics and characteristics of structure and characteristics of gray image extraction Hu moment invariants, gray co-occurrence matrix feature, local binary pattern features and Gabor, to extract the fractal dimension of texture image, get 2183 d characteristic parameters.By principal component analysis and linear uation analysis method of combining the characteristics of blade more feature dimensi)

绣花问题是连续型的填充,在不同区域的缝制过程中,缝针不能提针,因此不能用一般的离散型区
域填充方法处理。本文运用几何计算和图论理论提出了一个绣花缝针轨迹自动生成算法:先对轮廓走向进行
定义,通过轮廓铅垂方向的局部极值点的分割线将图案从上向下进行分割,采用交点的特征值比较彻底的解
决了分割时的重点问题,将图案区域准确的划分成缝针能一次完成的若干个节点。在此基础上根据节点的邻
接关系建立节点的邻接“图”,通过图论中半哈密尔顿路径或深度遍历方法找到节点的遍历(缝制)序列和每
个节点的缝制方向,最后可对设定的起点、终点和缝针间隔的条件自动提供缝针的走向轨迹。(In the process of embroidering, needle can not hang up for changing to a different area. Therefore, Embroider
problem could be abstract as a continuous area-filling work. Considering disperse area-filling methods can not process this
problem well. Based on geometry computing and graph theory, an algorithm of finding path of embroidering needle are
proposed in this paper. First, outline orientations are defined, and finding all local extreme points of inner outline on their
gravitational orientation to build sectioning lines so as to divide the picture. By using intersection point character the
overlap point problem was solved perfectly. Therefore, the picture is divided into some nodes which can be finished alone.
Then, based on connections of these nodes, an adjacency graph of nodes was built. Using half-Hamilton path or depth-first
search method, both embroidering sequence and direction of these nodes could be got from the graph. Finally, from a
defined start-point, end-point)
