MFCC参数的提取程序

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).)

为解决小升阻比月球返回舱再人大气层时安全性低、机动能力差的问题，本文提出采用一种带配平翼的中等升阻比返回舱做为月球采样返回舱,并对动压约束下轨迹优化问题进行了分析。构建一阶状态变量约東最优控制问题模型。然后采用庞德里亚金极大值原理以总吸热量最小为优化目标,对动压约束下再入轨道的初始再入段进行了优化设计,给出了升力系数的最优表达式。在最优轨迹的推导过程中，将问题分为自由段，约束段和自由段，并分别限定交界处的边值，最后问题变成了一个分段两点边值问题。

数值分析要求：第二题编成命令文件即可，其中阶乘可以单独编成函数文件在命令文件中调用，也可以直接在你所编的命令文件中利用循环语句直接计算； 第四题编成通用的程序，建议编成函数文件。提示：可以把多项式的系数和所需要求解的点设为参数。(Numerical Analysis of requirements: the second title of the command file can be compiled, which can factorial function into a separate file in order to call the document can also be made directly in your document, use the command loop direct calculation into fourth title common procedures, the proposed document into function. Tip: polynomial coefficients can be requested and the required parameters set point solution.)
