基于小波分析和主成分分析的人脸识别研究随着社会的发展，社会各个方面对快速有效的身份验证的要求日益迫切。由 于生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份 验证的理想依据。其中利用人脸特征又是最自然直接的手段，相比其他生物特征， 它具有直接、友好、方便的特点，易于为用户接受。从而，人脸识别吸引了越来 越多来自计算机视觉和信号处理等领域的关注，成为模式识别、图像处理等学科 的研究热点。(Based on wavelet analysis and principal component analysis of the Face Recognition With the social development of all aspects of society in his capacity as quickly and efficiently verify the requirements of increasingly urgent. Biological characteristics as a result of the inherent human attribute, has a strong individual differences in their stability and, therefore, is an ideal basis for authentication. The use of facial features which is the most natural means of direct, compared with other biological characteristics, it has a direct, friendly, convenient and easy for users to accept. Thus, face recognition has attracted more and more from the computer vision and signal processing and other areas of concern, as a pattern recognition, image processing, such as the research subjects.)

PV Array matlab file good for basisc

this is a simple matlab code for adding two numbers with basics tutorial

有限元分析计算的matlab程序，希望对大家有所帮助(finite element analysis of Matlab procedures, we hope to help)

两束相干光的干涉强度和干涉条纹,干涉条纹用图像指令image绘制(Interference of two beams of coherent light intensity and interference fringes)

This is a good demo of showing how the mean shift idea works for image pixel clustering

优点：1.对于信噪比高的信号滤波效果好； ％ 2.对于边沿的保护强过阈值滤波，不会产生阈值滤波情况下的过于平滑与Gibbs现象。 ％缺点：1.由于对边沿信号没做任何处理，所以边沿可能会有脉冲噪声保留下来； ％ 2.计算相关系数中，如果计算出来的小波系数点位置偏差大，则相关系数计算受影响； ％ 3.需要迭代运算，迭代的噪声能量阈值选取很重要，这里以开始段无信号处估计噪声； ％ 4.需要迭代运算，所以运算量比阈值法大； ％ 5.受分解层次影响，在大尺度上小波系数点位置偏差更大，相关系数计算不准确。 ％需要具体调整的地方：1.分解的尺度；()

说明：  使用感知准则进行分类（数据为线性可分的两类）(Perceptual criteria used to classify (the data for the linear separability of two))
