Description: WEAK 开发环境简介，介绍了WEKAWeka 试验（Experiment）环境可以让用户创建，运行，修改和分析算法试验，这会比单独的处理
各个算法更加方便。例如，用户可创建一次试验，在一系列数据集上运行多个算法（schemes），然后
2
分析结果以判断是否某个算法比其他算法（在统计意义下）更好。
可以通过Simple CLI 在命令行的方式下运行试验环境。例如，在CLI 上键入以下命令，将通过一
个基本的训练和测试步骤在Iris 数据集上运行OneR 算法。（注意该命令应放在同一行中输入CLI。）-WEAK development environment profile, introduced WEKAWeka test (Experiment) environment can allow users to create, run, modify and analysis algorithms test, which will deal with the various algorithms than the individual more convenient. For example, users can create an experiment in a series of data sets to run multiple algorithms (schemes), and then two results of the analysis to determine whether a particular algorithm than other algorithms (in the statistical sense) better. Simple CLI through the command line way to run test environments. For example, in the CLI, type the following command through a basic training and testing steps in the Iris data set to run on OneR algorithm. (Note that the order should be placed on the same line, enter CLI.)

findline——利用线性Hough变换和Canny边缘探测得到的线上各点的坐标
circlecoords——返回由圆的半径和圆心坐标决定的圆上各点像素的坐标
houghcircle——取一幅经过canny变换的图像，利用hough变换找到图像中的一个圆
findcircle——计算所得线上各点的坐标归纳出一个圆的半径和圆心，确定该圆的各点坐标
gaborconvolve——利用一维盖伯滤波器对图像进行处理
gethammingdistance ——返回两幅虹膜图像提取的特征码之间的海明距离
linecoords——返回一条线的上各点的x,y坐标值-nonmaxsup- non-maximum suppression hysthresh- set the threshold range, returns a binary image canny- edge detection, image edge enhancement adjgamma- adjust the image' s gamma value findline- linear Hough transform and Canny edge detection get the coordinates of each point circlecoords online- Returns coordinate houghcircle on the circle of the radius and center coordinates of the points decision pixels- After taking a picture canny transformation, using hough transform to find the image of a circle findcircle- the calculated coordinates of each point line summed up a circle of radius and center, to determine the coordinates of each point of the circle gaborconvolve- using a 维盖伯 filter for image processing gethammingdistance- returns two iris images extracted linecoords Hamming distance between the signature- a return line to the points on the x, y coordinate values

Description: Free表示自由，开放，共享， iris为希腊神话中的彩虹女神，宙斯的通信官· 从2005年起Freeiris项目由开源通信爱好者和开源软件推动者所创建的一个平台， 将理念， 技术， 信仰融合在了一起。
Freeiris的代码最早由hoowa.sun编写并以开放源代码软件的形式公布到全世界, 现在已经有了大量的用户. Freeiris实现了更容易方便的传统电话线, ISDN-BRI, 数字中继 ISDN-PRI, 中国7号线路的支持. Freeiris同样也广泛的支持SIP和IAX2这种网络通信协议. 同时支持包括中国,美国,欧洲标准的电话系统以便在商用领域实现融合.
Freeiris(前身为Astercon2)是一款开源的电话通信平台，含盖了计费、注册管理、PBX、数字中继、呼叫中心等业务需要。系统基于Asterisk、Perl、Linux、PHP等技术实现，在不修改asterisk本身的情况下采用外挂形式开发。目前系统可以控制管理SIP、IAX、H323、等软协议的通信。在硬件层上，支持大量的硬件产品，包括数字中继(ISDN PRI / ISDN BRI)，模拟中继(FXO / FXS)，以及各种SIP与IAX的终端设备等。由于freeiris项目将完全停止，包括下载服务器也随即关闭，这里上传收藏一下啊，为freeiris项目做一下备份。-Free said that freedom, openness, sharing, iris for rainbow goddess in Greek mythology, Zeus platform communication officer from 2005 Freeiris open source communications project by enthusiasts and promoters of open source software is created, the concepts, technologies, beliefs fused together. Freeiris code was first written by hoowa.sun and in the form of open source software released to the world now have a large number of users. Freeiris achieve a more easy and convenient traditional telephone lines, ISDN-BRI, digital trunk ISDN- PRI, to support China on the 7th line. Freeiris also broad support SIP and IAX2 this network communication protocols at the same time support, including China, the United States, the European standard telephone system in order to achieve integration in the commercial field. Freeiris (formerly known as Astercon2) is an open source telephony platform, covering the business needs billing, registration management, PBX, digital trunking, call center. System base
