Highcharts 是一个用纯JavaScript编写的一个图表库， 能够很简单便捷的在web网站或是web应用程序添加有交互性的图表，并且免费提供给个人学习、个人网站和非商业用途使用。HighCharts支持的图表类型有曲线图、区域图、柱状图、饼状图、散状点图和综合图表。

数字识别代码 第一步：训练网络。使用训练样本进行训练。（此程序中也可以不训练，因为笔者已经将训练好的网络参数保存起来了，读者使用时可以直接识别）第二步：识别。 首先，打开图像（256色） 再次，进行归一化处理。点击“一次性处理” 最后，点击“R”或者使用菜单找到相应项来进行识别识别的结果显示在屏幕上，同时也输出到文件result.txt中 该系统的识别率一般为90％ 另外，也可以单独对打开的图片一步一步进行图像预处理工作。但要注意，每一步工作只能执行一遍，而且要按顺序执行。步骤为：“256色位图转为灰度图”“灰度图二值化”“去噪”“倾斜校正”“分割”“标准化尺寸”“紧缩重排” 另外注意，要识别的图片，要与win.dat、whi.dat位于同一目录。此两文件保存训练后网络的权值参数 -digital identification code first step : training network. Use of training samples for training. (These procedures also can not training because I have trained network parameters saved, Readers can direct identification) second step : identification. First, open the Image (256 colors) again, to a treatment. Click on the "one-stop" Finally, Click on the "R" or use the menu item corresponding to find the identification of the identification results on the screen, also result.txt output to a file which the system"s recognition rate of 90% for the other, can be individually opened to the step-by-step pictures for image prep

数字图像处理,离散余弦dct变换域中水印的提取-digital image processing, discrete cosine transform domain Extra watermark extraction

采用canny边界检测和hough变换分离虹膜，归一化，采用haar小波提取虹膜特征及海明距进行识别-Using canny edge detection and hough transform separation of the iris, normalized using haar wavelet extracted iris characteristics and hamming distance to identify

因为VTK可视化工具包具有的强大的功能，可视化领域的研究人员很多都在应用它。本压缩包是在VC下编写的一个使用vtk实现量化坐标后的球例程。-Because the VTK visualization toolkit with powerful functionality, visualization research in the field of personnel and many of them in the application of it. The compressed packet is prepared with a VC VTK realize the use of coordinates to quantify the ball after the routine.
