局部SMQT特征的人脸检测

Demonstration script for envelope detection. The message signal is +1 for 0 < t < t0/3, -2 for t0/3 < t < 2t0/3, and zero otherwise.(Demonstration script for envelope detection. The message signalis+ 1 for 0 <t <t0/3,-2 for t0/3 <t <2t0/3, and zero otherwise.)

课程设计时编写的matlab程序代码，供做算法研究人员参考，小波包分析提取振动信号中的特征频率。( Course designed to prepare the matlab program code, Algorithm for researchers to do reference, Wavelet packet analysis to extract vibration signal characteristic frequency.)

滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

现代谱估计研究中的经典方法研究仿真，如均方差等。(Modern Spectral Estimation of classical methods of simulation studies.)

说明：  SIFT特征点的提取和匹配，SIFT算法首先在尺度空间上进行关键点检测，确定关键点的位置和关键点所处的尺度，然后使用关键点邻域梯度的主方向作为该点的方向特征，最后由关键点邻域梯度信息生成关键点的特征向量(SIFT algorithm firstly detects the key points in the scale space, determines the location of the key points and the scale of the key points, then uses the main direction of the key point neighborhood gradient as the direction feature of the point, and finally generates the feature vector of the key points from the key point neighborhood gradient information)

将方波周期信号展开成傅里叶级数并生成3次，5次，8次，10次谐波(Expand the square wave into a Fourier series of periodic signal and generates 3 times, 5 times, 8 times, 10 times harmonic)

潮流程序，多初学入门者很好使，，分了多个模块，每个模块均有说明 (Trend of the program, more than the novice beginners to very good make, and divided into multiple modules, each module has a description of)
