MATLAB-PWM

这是一篇讲解Matlab的一些简单的使用操作以及程序，对新手是很好的。(This is one to explain the use of some simple Matlab operations and procedures, the novice is very good.)

This file compares three different versions of the Kalman filter. The Kalman filter is used for recursive parameter estimation. The Kalman filter can handle noisy measurements. The first implemented filter (fcn_KF) is the Kalman filter with standard update of the covariance matrix P. The covariance matrix reflects the uncertainties of the predictions. To improve the numerical stability Potter developed a square root update (fcn_KF_SRP) of the covariance matrix P. Another version is the square root covariance update via triangularization (fcn_KF_SRT). This file generates a model. Then the three Kalman filters perform an estimation of the model parameter. At the end the results are compared. Sources: Simon, D. (2006): Optimal state estimation Kaminski, P. (1971): Discrete Square Root Filtering: A Survey of Current Techniques Golub, G.

图像配准定义为：对从不同传感器、不同时相、不同角度所获得的两幅或多幅图像进行最佳匹配的处理过程.图像配准需要分析各分量图像上的几何畸变，然后采用一种几何变换将图像归化到统一的坐标系统中。在配准过程中，通常取其中的一幅图像作为配准的标准，称之为参考图像；另一幅图像作为配准图像(Image registration algorithm)
