Labview中使用Access和SQL数据库的方法。总结的文档和实例代码。

用python编写的决策树ID3算法，运用了Car-Evaluation的例子。BUG较少，综合了网上的优秀代码，并进一步形成自己的代码。代码基本有注释，风格良好，能够很快看懂。内含有比较规范的报告文档，包含所有流程图，说明图，以及文档风格绝对不错，无需更改，建议下载！该算法所测试的数据集如下（已经打包在内，并已经生成xls格式，方便直接使用）：已知：UCI标准数据集Car-Evaluation，定义了汽车性价比的4 个类别；求：用ID3算法建立Car-Evaluation的属性描述决策树Car-Evaluation训练数据集文件：1. car_databases.pdf

matlab 相机标定代码 摄像机标定(Camera calibration)简单来说是从世界坐标系换到图像坐标系的过程，也就是求最终的投影矩阵的过程。[1]基本的坐标系：世界坐标系；相机坐标系；成像平面坐标系；像素坐标系[2]一般来说，标定的过程分为两个部分：第一步是从世界坐标系转为相机坐标系，这一步是三维点到三维点的转换，包括R，t（相机外参，确定了相机在某个三维空间中的位置和朝向）等参数；第二部是从相机坐标系转为成像平面坐标系（像素坐标系），这一步是三维点到二维点的转换，包括K（相机内参,是对相机物理特性的近似）等参数；投影矩阵 ： P=K [ R | t ]

Its performance depends largelyon the seleclion of seed points and growth rules. In order Lo extract snail images with such methods more effectively.The article analyzes the basic idea of the seeded region growing method(SRG) and presents an improved seededregion growing method (ISRG) which is used to extract the snail images. In ISRG, novel similarities rules and anew dynamic threshold method are adopted. For the complex and various habitat of snail, ISRG selects the region growing seed points manually. It is demonstrated by experimental results that ISRG can achieve better snailimage extraction results under the complicated real-world sceneKey words: seeded region growing (SRG; image extraction; dynamic threshold; snail(E D:X, JC1994-2012ChinaAcademicJournalElectronicPublishingHouse.Allrightsreservedhtlp://www.cnki.net
