说明：  高斯投影正反算，将大地坐标转换为平面直角坐标系的坐标。(Positive and negative Gauss projection operator, the geodetic coordinates into Cartesian coordinates the coordinates.)

MATLAB 计算医学图像的配准，融合 基于SIFT方法的配准()

最大最小距离 聚类算法，可以对一维或者二维信号进行聚类分析。尤其是两类化情况较好时。(maxmum and minimum Cluster Algorithm)

时隙 ALOHA（Slotted ALOHA）算法是在纯ALOHA 算的基础上将时间分成了多个离散的时隙，被分割成的时隙的长度要大于标签所携带数据信息帧的长度(Slot ALOHA (Slotted ALOHA) algorithm is based on pure ALOHA time will be counted into the slot more discrete, divided into the slot length is greater than the length of the data label information carried by the frame)

HOG特征提取源代码，这份代码是针对行人检测编写的，可以根据个人需要设置参数。(HOG Feature Extraction source code, this code is written for pedestrian detection, you can set the parameters according to individual needs.)

在rgb颜色空间实现的单高斯模型，用于目标检测(In rgb color space to achieve a single-Gaussian model for target detection)

四个IMAGE窗口，分别对图像进行读取，最大值滤波，最小值滤波及中值滤波。(Four IMAGE window, read the image, respectively, maximum filter, the minimum filter and median filter.)

在这个程序中，我们读取两张图像，进行特征匹配。然后根据匹配得到的特征，计算相机运动以及特征点的位置。这是一个典型的Bundle Adjustment，我们用g2o进行优化。
