只是关于MATLAB界面编程的书籍，内涵例题，讲解详细(This is a book about MATLAB programming interface, easy to understand, containing examples code.)

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.

人脸对齐基于论文《fps3000》中训练集构建时生产68个特征点的matlab脚本文件。提供交互窗口，按顺序点左眼右眼和嘴巴，即可自动生成68个点，再用鼠标对个别点进行人工修正。满意后保存即生成一个文本文件，存有68个点的坐标。(Face aligned on the paper fps3000 production when the training set to build 68 feature points matlab script file. Provide interactive window, press the right and the left dot sequence mouth, you can automatically generate 68 points, then the mouse on the individual points manually corrected. The satisfaction of saving a text file that is generated, there are the coordinates of 68 points.)

用radon变换提取图像的不变形特征，将图像转回原有角度，用于后续识别(Radon transform to extract images with no deformation, the image back to the original point of view for subsequent identification)
