掌握OpenGL中的矩阵变换、模型视图变换及投影变换。(The perspective projection, main view, overhead view and side view of the space tetrahedron shown in Figure 7-41 of the textbook P228 are displayed in four viewing areas using the multi-view area in OpenGL.)

说明：  60轨CAD断面图，严格按照国家标准作图，60轨CAD断面图(Cross-sectional drawing of 60-rail CAD)

使用4阶龙格库塔定理计算一阶微分方程组，方程组有3个方程(RK calculation of differential equations)

说明：  李春明于2005年提出的CLIC，一种对MR图像偏移场矫正方法(Li Chunming's CLIC in 2005, an offset correction method for MR images.)

BTC的基本方法,并且编程实现,显示,观察编码后的图像,推荐给大家(BTC basic method and programming implementation, display, observe the encoded image, recommend to everyone)

ASIFT算法实现，C++,对有仿射变换的图像匹配更加准确，想比SIFT算子匹配点数多(ASIFT algorithm, C++, affine transformation of the image matching more accurate, want to match more than SIFT operator points)

自动种子区域生长代码，用MATLAB运行，不必选择种子点 可以自动选择阈值 实现图像分割(Automatic seeded region growing code, using MATLAB operation, do not need to select seed points can be automatically selected threshold image segmentation)

利用正则化方法对模糊图像进行恢复的算法，产生一幅图象，然后加入噪声后对特定的输入正则化参数其进行图象恢复。(The use of regularization method for the restoration of blurred images of the algorithm, resulting in an image, and then adding noise to the input of specific parameters of regularization to restore its image.)

说明：  a）针对合成纹理图像（共有4 个合成纹理图像，见文件夹： Texture_mosaic_data）中每一个像素提取纹理特征向量； b）利用聚类技术（推荐用k‐均值聚类，可以从网上查找原码）对特征向 量空间中的点进行聚类，类别数可根据图像中的实际纹理类数确定。最后把类 属标签映射成图像形式显示（如下图，其中b、d、f、h 为相应的基准分割图像）。(A) for synthetic texture images (there are 4 synthetic texture images in total, see the folder: Texture feature vector is extracted from every pixel in texture; B) use clustering technology (K-means clustering is recommended, and the original code can be found on the Internet) to search the feature direction The number of categories can be determined according to the actual number of texture classes in the image. Last class The generic label is mapped to an image (as shown in the figure below, where B, D, F, h are the corresponding reference segmentation images).)

超声相控阵声场仿真程序，可以对相控阵探头的声场进行仿真(The ultrasonic phased array acoustic field simulation program can simulate the sound field of phased array probe)
