该程序用于比较KF、EKF、UKF滤波器的不同(The program is used to compare KF, EKF, UKF filter)

该算法用于自回归输入模型，是一种迭代的算法。其基本思想是基于对数据先进行一次滤波处理，后利用普通最小二乘法对滤波后的数据进行辨识，进而获得无偏一致估计。但是当过程的输出信噪比比较大或模型参数较多时，这种数据白色化处理的可靠性就会下降，辨识结果往往会是有偏估计。数据要充分多，否则辨识精度下降。模型阶次不宜过高。初始值对辨识结果有较大影响。(The algorithm used for autoregressive input model, it is a kind of iterative algorithm. The basic idea is based on data to conduct a filtering processing, after using ordinary least square method to identify the data filter, and then obtain unbiased consensus estimates. But when the process output signal-to-noise ratio is larger or model parameters are too, this kind of data white processs reliability will drop, identification results tend to be biased estimate. Data should fully, otherwise the identification accuracy down. Model order time shoulds not be too high. Initial value to identification results have great influence on.)

先生成这样的一幅500*500的RGB彩色图像：一个田字格，左上和右下是绿色，右上是红色，坐下是蓝色。并进行如下处理：（a）将该图像转换到HSI空间，用25*25的平均模板模糊H分量图像，再转换回RGB空间；（b）重复（a），只是这次处理的是S分量。最后简单分析结果。（内含实验报告） (Mr. into a 500* 500 RGB color image: a field word lattice, the upper left and lower right is green, the upper right is red the sit is blue. And be handled as follows: (a) the image into the HSI space, fuzzy H 25* 25 average template component image, and then converted back to RGB space (b) Repeat (a), only this time to deal with the S component . Finally, a simple analysis of the results. (Contains experimental report))
