There are three main methods in face localization: localization according to face outline, localization according to complexion and localization according to templates constructed by some standard sample images. As to feature extraction, it can be divided into two parts because face features can be divided into geometrical features and algebraic features. While extracting geometrical features, the features of eyes, nose, mouth, eyebrows can be gained by some image processes: binary, sharpen, smooth, projection, calculating gradient and so on. In order to extract algebraic features, we can do some mathematical transformation for the digital images such as singular value decomposition, K-L transformation.

在人脸检测部分，目前存在的方法有利用人脸的几何轮廓进行检测、利用人脸的肤色信息进行检测、构造标准人脸模板进行匹配检测等等；在人脸特征提取部分，可以用一些图像处理的方法如投影、二值化、求梯度图像等提取人脸中各特征器官如眼睛、鼻子、嘴巴等的几何特征，另外也可以借助于数学变换，求取人脸图像的一些代数特征，如对图像进行奇异值分解，以奇异值代表图象的特征，或对图像进行K-L变换，以图像在构造的特征空间上的投影系数作为图像的特征等；在识别部分，可以通过距离度量或相似度来判断输入图像与样本图像的匹配程度，还可以通过神经网络方法进行人脸的识别。

It is found that generally the hydrologic noises exhibit skew characteristics, so that it is reasonably to use skew probability distribution to describing the noise components, and the wavelet coefficient threshold obtained by optimal entropy criterion based on information entropy theory in the global optimum.

分析结果显示，水文序列中的噪声成分具有偏态特性，因此本文应用偏态分布线型对噪声成分进行描述更为合理，而且小波系数阈值优选熵准则所得的阈值是基于信息熵理论而确定的，因此是整体上最优值。

The median velocity was calculated instead of the mean because it is fairly common to find outliers (e.g., breaking a ski pole during the race would make the velocity very low and aberrant).

这里计算的是速度中间值而不是平均值，这是因为中间值较容易发现异常值（例如，在比赛中打破一个滑雪杆会使速度变得异常低）。

Several interpolation methods are introduced, and their simulation results are compared, and cubic spline interpolation is proved to be the best.

Finally, it should be obvious that you could just write a subroutine whose return value is one of the EXCEPTION_Xxx values

最后，很明显的你应该值编写一个子程序，其返回值是 EXCEPTION_Xxx值中的一个。

The results show that the suppositional meteorological stations can greatly improve the interpolation accuracy, and the ordinary Kriging method was the best among the three selected methods.

结果表明：模拟站点的加入大大提高了插值的精度；采用的3种插值方法中，普通克里格法比反距离加权法和径向基函数法具有更为理想的插值效果。

In recent years, set-valued optimization make much progress. In Chapter 5, based on Clarke tangent cone, we establish epiderivative of a class of set-valued maps and its properties. And furthermore, sufficiency optimization conditions of set-valued optimization are also obtained.
