说明：  生物特征识别技术作为一种身份鉴别手段具有独特的优势。在生物特征识别系统中, 采集数据的预处 理是不可或缺的环节。以人脸识别为例, 介绍了一种在复杂背景的彩色图像中, 基于颜色和知识的生物特征预处理 方法。首先利用颜色信息从图像中分割出类肤色区域, 然后运用人脸几何特征和眼睛的提取定位人脸。仿真实验表 明, 该算法能较为准确地定位彩色图像中的正面或小角度偏转的人脸, 具有较快的运算速度。(Biometrics as an identification tool has a unique advantage. In biometric systems, collect data preprocessing is an indispensable link. To face recognition, for example, presents a complex background in color images based on color and knowledge of the biological characteristics of pretreatment. The first to use color information to separate out the classes from the image color region, and then use face extraction of geometrical features and eye positioning face. Simulation results show that the algorithm can be more accurately locate color images in a positive or small-angle deflection of the face, with a faster computational speed.)

fft calculation of any input signal

自己编写的一个大批量不同类别数据录入程序，并且为防止因为数据量太大导致程序运行缓慢，将其改写成分批小规模数据。方便了大规模数据处理慢带来的各种不变。(I have written a large quantities of different types of data entry procedures, and because the amount of data in order to prevent too much causes the program to run slowly, be rewritten into small batches of data. Facilitate the large-scale data processing slow and the various unchanged.)

是国外的成品模型，music高阶谱分析算法，用于特征降维，特征融合，相关分析等。( Foreign model is finished, music higher order spectral analysis algorithm, For feature reduction, feature fusion, correlation analysis.)

提出一种基于Teager能量算子的小电流接地 系统的单相故障选线方法。通过EMD时空滤 波，在故障线路零序电流中提取暂态分量作 为特征量，以Teager能量算子法求得暂态分 量的瞬时频率、实际频率和幅值，进而得到 信号的能量均值，再以能量均值为故障判 据，从而检测出故障线路。经Matlab/Simulink 仿真验证，结果表明该方法的有效性，且算 法简便(Single-phase fault line selection method for the system. Time-space filtering through EMD)

利用MATLAB软件对学生的各项信息进行统计，然后按照学生的成绩进行排名。(MATLAB software statistics the information to the students, and then ranked according to the students' academic achievement.)
