Mechanical-fault-diagnosis-method
- 经验小波变换(EWT)是一种新的自适应信号分解方法, 该方法继承了EMD 和小波分析方法的各自优点, 通过提取频域极大值点自适应地分割傅里叶频谱以分离不同的模态, 然后在频域自适应地构造带通滤波器组从而构造正交小波函数, 以提取具有紧支撑傅立叶频谱的调幅-调频(AM-FM)成分。本文将该方法引用到机械故障诊断中, 提出了一种基于经验小波变换的机械故障诊断方法, 并与EMD方法进行了对比分析。仿真结果表明, 经验小波变换方法明显优于EMD方法, 能有效地分解出信号的固有模态。与EMD 相比较, 该
ECG-signal-denoising
- 在心电信号处理过程中,为了避免产生Gibbs 振荡现象和严重的频率混叠现象,提出一种基于双树复小波变换,并结合最大后验估计确定阈值的心电信号去噪方法。文中采用了信噪比和均方误差来评价双树复小波变换和离散小波变换两种方法对心电信号的去噪效果。实验结果表明: 与传统离散小波变换相比,双树复小波变换去噪更彻底,边界、纹理等特征能较好地保留,可以作为一种生物医学信号降噪处理的新方法。-In ECG signal processing, in order to avoid the phenomena of

MSc---Orthogonal-vs-Biorthogonal-Wavelets-for-Ima
- Eective image compression requires a non-expansive discrete wavelet transform (DWT) be employed consequently, image border extension is a critical issue. Ideally, the image border extension method should not introduce distortion under compressio
