利用聚类技术实现纹理分割
说明： a）针对合成纹理图像（共有4 个合成纹理图像，见文件夹：
Texture_mosaic_data）中每一个像素提取纹理特征向量；
b）利用聚类技术（推荐用k‐均值聚类，可以从网上查找原码）对特征向
量空间中的点进行聚类，类别数可根据图像中的实际纹理类数确定。最后把类
属标签映射成图像形式显示（如下图，其中b、d、f、h 为相应的基准分割图像）。(A) for synthetic texture images (there are 4 synthetic texture images in total, see the folder:
Texture feature vector is extracted from every pixel in texture;
B) use clustering technology (K-means clustering is recommended, and the original code can be found on the Internet) to search the feature direction
The number of categories can be determined according to the actual number of texture classes in the image. Last class
The generic label is mapped to an image (as shown in the figure below, where B, D, F, h are the corresponding reference segmentation images).)

Objective: To realize the intensity distribution of the pattern on the focal plane behind the lens.
Realization:
1. Wavelength, aperture, shape, incident wavefront, two-dimensional target distribution and size of diffractive optical elements can be set by themselves.
2. The phase is quantized by 8 steps and recalculated.
3. Replace the sampling interval of the output surface and recalculate it.)

dual-tree
首先将非平稳的故障振动信号进行双树复小波包分解，得
到不同频带的分量；然后对每个分量求其峭度值和相关系数并进行比较；最后选取峭度值和相关系数较大的分量
进行软阈值降噪和双树复小波包重构，即可有效地消除振动信号中噪声的干扰，同时保留信号中的有效信息即实
现了故障特征信息的提取。(In view of the above situation, a new fault diagnosis
method is proposed based on dual-tree complex wavelet packet transform and threshold de-noising. Firstly, the
non-stationary fault signal is decomposed into several different frequency band components through dual-tree
complex wavelet packet decomposition. Secondly, Kurtosis and the cross-correlation coefficient of each
component are obtained and compared. Due to the kurtosis reflecting the signal variations, if the kurtosis value is
bigger, the degree of the change of signal is bigger too. The correlation coefficient can reflect the proximity
between the component and the original signal at the same time, the correlation coefficient is bigger, the more
similar with the original signal. Finally, the components that have a bigger value are chosen to be de-noised by a
soft threshold and reconstructed by dual-tree complex wavelet packet transform. The noise interference was
eliminated effectively, and the effective si)
