一个简单的人脸识别演示使用PCA算法。pca_svm_face_recogition.m是一种Matlab代码，它利用PCA实现人脸识别程序，降低特征的维数，并利用one-vs-one多类SVM对图像进行分类。
我使用PCA将数据缩减到50维，然后使用SVM线性核函数进行分类，最终得到了0.9437的准确率。

水平集是跟踪轮廓和表面运动的一种数字化方法。不直接对轮廓进行操作，而是将轮廓
设置成一个高维函数的零水平集，这个高维函数叫做水平集函数：Ψ(X,t) 。然后水平集函数
运动成为一个微分方程。在任何时候，通过从输出中提取零水平集 (( ), ) { ( , ) 0} Xt Xt Γ =Ψ = 来
得到运动的轮廓。使用水平集的主要优点是可以对任何复杂的结构进行模式化和拓扑变换，
比如暗中操作融合和分离。
The paradigm of the level
set is that it is a numeri-cal method for tracking the
evolution of contours and
surfaces. Instead of ma-nipulating the contour di-rectly, the contour is embed-ded as the zero level set of a higher dimensional function called the level-set function,ψ(X,t). The level-set func-tion is then evolved under the control of a differential
equation. At any time, the
evolving contour can be ob-tained by extracting the zero
level-set Γ((X),t) ={ψ(X,t) =0}from the output. The main advantages of using level sets is that arbitrarily complex shapes can be modeled and topological changes such as merging and splitting are handled implicitly. (2013-08-10, MultiPlatform, 8KB, 下载5次)

在128*128的网格上求解2维波动方程来模拟大范围的水波。用一个像素渲染程序完成对波动方程的时间积分，结果存放于一个浮点数纹理中，.然后将此纹理传给渲染模块。此外使用凹凸贴图来描述水面的细节波纹，这会给稍后的逐像素渲染带来逼真的水面闪烁高光效果.
