信道容量的C实现，附详细注释

资源描述polar码，基于信道极化，分为好信道和坏信道，满足要求的好信道用于传输信息比特，坏信道用于传输冻结比特。先用BEC构造获取冻结比特位置，在此基础上传输0比特，其他位置传信息比特。输入SC译码算法为信道转移概率，译码算法属于串行译码算法。当前获得译码判决比特，用于下一比特的译码比特的判决。

应用背景 It approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.关键技术This is achieved by relying on integral images for image convolutions; by building on the strengths of the leading existing detectors and descriptors (in casu, using a Hessian matrix-based measure for the detector, and a distribution-based descriptor); and by simplifying these methods to the essential. 

这是一段关于四种排序方法的完全源代码及其相互之间的比较,包括:Heap sort,Merge sort,Quick sort,Radix sort-This is a period of about four kinds of methods to sort the complete source code and the comparison between, including: Heap sort, Merge sort, Quick sort, Radix sort

在测绘或地图学中，经常会需要用高程点生成DEM，一般首先由这些点按最小原则生成三角网，此代码即是根据任意多个点生成Delaunay三角网功能。-In the mapping or cartography often elevation point will need to generate DEM, generally the first point from these principles by the smallest triangulation generated, the code that is generated in accordance with any number of points, Delaunay triangulation function.

应用背景应用于遥感影像的重采样，可以重采样成各种你所需要的分辨率的影像。如30m分辨率的遥感影像，可以重采样成3km，也可以重采样成10m分辨率的影像。关键技术利用GDAL进行编写的，支持最邻近，双线性内插法，三次卷积法，均值法，B样条等重采样算法，具体参见gdalwraper.h。
