二进小波和非线性变换的图像增强项目 二进小波和非线性变换的图像增强项目(Image enhancement project based on two in wavelet and nonlinear transform)

说明：  实现k-l变换，代码短，效率高，适合初学者进行上机练习，原理简单，比较容易懂和实现。(Achieve kl transformation, the code short, high efficiency, suitable for beginners to practice on the machine, simple in principle, relatively easy to understand and achieve.)

用matlab编写的提升小波算法，应用于图像处理，很好用(Matlab prepared using lifting wavelet algorithm used in image processing, very good use)

采用小波变换的方法实现心电信号的滤波，分别使用了硬阈值、软阈值和改进阈值方法，并实现了滤波效果的评价（均方差和信噪比）(Wavelet transform of ECG signal filtering method, respectively, using a hard threshold and soft threshold and improve the threshold method, and to achieve the filtering effect of the evaluation (both variance and signal to noise ratio))

以labview为平台通过小波分析方法对波形进行处理。(Labview as a platform for analysis of the waveform by wavelet processing.)

实现信号希尔伯特变换，以及小波变换，小波变换要求数据长度是2的N次幂(The signal Hilbert transform and wavelet transform, wavelet transform requires that the data length 2 is N th)

该程序主要是通过小波变换来实现对心音信号的去噪处理(The program is mainly achieved by wavelet denoising of heart sound signals)

针对滚动轴承信号的特点，构造脉冲响应小波，采用连续小波变换的方法提取滚动轴承故障信号，提出两种诊断方法。(For Rolling signal characteristics and tectonic pulse response wavelet using continuous wavelet transform to extract the rolling bearing fault signals, and proposed two diagnostic methods.)

说明：  用MATLAB编程实现实现滤波，与数字信号处理相关(Implementing filtering)
