用于消除电网中由非线性负荷导致产生的5/7次谐波，降低畸变率(Eliminate the 5/7 subharmonic in the power grid and reduce the distortion rate)

lstm网络的建立、训练及应用实例，测试过，可用。(LSTM network establishment, training and application examples, tested, available.)

说明：  对原始图像添加椒盐噪声，并用邻域平均和中值滤波法进行滤波，并可以进行对比。(Add salt and pepper noise to the original image, and with neighborhood average and median filtering method for filtering, and can be compared.)

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.)
