对高光谱图像进行目标检测，首先滤波处理然后降维，利用输出能量最小原则用于探测亚像元的小目标。(In target detection of hyperspectral images, first filter processing and then dimensionality reduction are used to detect sub-pixel small targets by using the principle of minimum output energy.)

相机标定过程中，对初始得到的内外参数的进行整体优化，从而得到最佳内外参数的程序(Camera calibration process, the overall optimization of the initial parameters obtained inside and outside, resulting in the program inside and outside the parameters of the best)

说明：  序贯滤波程序： 卡尔曼滤波算法（Kalman filtering）一种利用线性系统状态方程，通过系统输入输出观测数据，对系统状态进行最优估计的算法。由于观测数据中包括系统中的噪声和干扰的影响，所以最优估计也可看作是滤波过程。 　　序贯算法又叫序贯相似性检测算法，是指图像匹配技术是根据已知的图像模块(模板图)在另一幅图像(搜索图)中寻找相应或相近模块的过程，它是计算机视觉和模式识别中的基本手段。已在卫星遥感、空间飞行器的自动导航、机器人视觉、气象云图分析及医学x射线图片处理等许多领域中得到了广泛的应用。研究表明，图像匹配的速度主要取决于匹配算法的搜索策略。 　　(Sequential filtering procedures: Kalman filtering (Kalman filtering) is an algorithm that uses the state equation of a linear system to estimate the optimal state of the system through the input and output observation data of the system. Because the observation data include the influence of noise and interference in the system, the optimal estimation can also be regarded as a filtering process.)

均值变点是统计学中常用的变点分析方法，其主要思想如下： 假设有一组数据，随着某个指标变化（增大），其值逐渐增加并趋于稳定，如何判断在这个过程中是否出现了突变的情况，异样的情况？ 均值变点分析方法提供了一种思路，大概如下： 1 计算总的均值和方差； 2 循环将这组有序数据分成两组，X1，X2 计算各组的均值和方差， 计算总方差与分组方差之和的差； 3 得到变点(The change point of mean is a commonly used change point analysis method in statistics. Its main ideas are as follows: If there is a set of data, as a certain index changes (enlargement), its value increases gradually and tends to be stable. How to judge whether there is a sudden change in the process and the unusual situation? The mean change point analysis method provides a way of thinking, which is as follows: 1 the total mean and variance are calculated. The 2 cycle divides the ordered data into two groups, X1, X2. Calculate the mean and variance of each group. The difference between the sum of the total variance and the group variance is calculated. 3 get a change point)
