信号处理是结构健康监测系统一个重要组成部分。小波变换作为有效的信号处理工具能对被分析信号进行更细致分析，获得比傅立叶分析更多的信号特征。将小波分析应用于航空结构材料的结构健康监测中，对检测信号进行时频局部化处理，获得与结构状态相联系的特征。-Signal processing is a structural health monitoring system an important part. Wavelet transform as an effective signal processing

This an implementation of the algorithm for calculating the Structural SIMilarity (SSIM) index between two images.- This is an implementation of the algorithm for calculating the Structural SIMilarity (SSIM) index between two images.

利用小波变换实现对故障信号的特征提取 构造特征向量-Wavelet transform feature extraction of fault signals structural feature vector

对结构损伤加速度值进行小波分析，再对其加载噪声，最后进行去噪处理-Acceleration values for structural damage analysis, and then the noise of its load, and finally de-noising
