PCA、LDA人脸检测，压缩包里实现了PCA、LDA、最小距离分类器，人脸检测！(PCA, LDA face detection, compression bag to achieve the PCA, LDA, minimum distance classifier, face detection!)

利用霍夫曼方法进行图像的霍夫曼编码与解码(Hoffman method using images of the Hoffman encoding and decoding)

说明：  ：建立了碳钢渗硫表面和非渗硫表面的多球凸峰面接触模型，模型中，凸峰高度按高斯函数分布．用塑性流线 理论分析了渗硫层的摩擦系数．计算结果表明：摩擦系数随载荷的增加而增加；相同粗糙度下，磨削加工的摩擦系 数比车削加工的摩擦系数大；摩擦系数随着渗层厚度的增大而增大．从减小摩擦系数的角度来考虑，渗硫层并非 越厚越好． (the multi-asperity sphere-shape model for surface contact between sulphurized layer and unsulphurized layer is established．in which the height of sphere-shape asperities follows the Gaussian distribution．1he frictional coeficients of sulphurized layers are analyzed by using plastic flown line theory．1he results show that the frictional coeficient increases with the load．the frictional coeficient of ground surface is higher than that of tumed surface in case of the same roughness．1he thicker the sulphuri[ed layer is．the higher the frictional coeficient is．From the viewpoint of reducing frictional coeficient，the thickness of sulphurized layer should be smaller．)

合成孔径雷达目标的特征提取及其识别技术。国防科大写的！(synthetic aperture radar target feature extraction and recognition technology. Written by which this university!)

说明：  实现了离散小波变换和连续小波变换，用于小波分析。(Discrete wavelet transform and continuous wavelet transform are implemented for wavelet analysis.)

用matlab实现标准四步相移条纹,可自己设定条纹的高度和宽度；最后得到包含相位信息的条纹包裹图。(Using matlab to achieve the standard four-step phase shift stripes, stripes can set their own height and width finally get the phase information contained stripes wrapped map.)
