blur filter for image in c

本代码实现了SIFT算法，首先获得差分图像尺度空间，寻找局部极值点，找到关键点，然后，对关键点生成特征描述符。实验效果很好。

用vc编写的数字识别系统，能够识别0到9共十个数字-Vc prepared using digital identification system to identify a total of 0-9 10 figures

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实现用三角片组成球的例程。-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 the composition of the ball with a triangular piece of routine.

使用说明                                   代码注释的很详尽第一步：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情况下为90%。此外，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。具体步骤为：“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”。注意，待识别的图片要与win.dat和whi.dat位于同一目录，这两文件保存训练后网络的权值参数。

本程序绘制打开闭合的曲线，闭合曲线可以使用Brush对象填充-mapping procedures to open the closed curve, closed curves can be used to fill Brush object

通过openGL加载ase的模型文件，并显示在窗口中，此源码用于读取ASE类型的文件，ASE文件可以由3DMAX导出，导出后由该源码读取，并显示其中表示的模型。

Cognitive radio frequency spectrum detection-The spectrum sensing of a wideband frequency range is studied by dividing it into multiple subbands. It is assumed that in each subband either a primary user (PU) is active or absent in a additive white Gaussian noise environment with an unknown variance. It is also assumed that at least a minimum given number of subbands are vacant of PUs. In this multiple interrelated hypothesis testing problem, the noise variance is estimated and a generalised likelihood ratio detector is proposed to identify possible spectrum holes at a secondary user (SU). Provided that it is known that a specific PU can occupy a subset of subbands simultaneously, a grouping algorithm which allows faster spectrum sensing is proposed. The collaboration of multiple SUs can also be considered in order to enhance the detection performance. The collaborative algorithms are compared in terms of the required exchange information among SUs in some collaboration
