针对齿轮滚动轴承等的早期损伤类故障, 提出将小波包分解作为包络分析的前置处理手段以提取振动信号的故障信息特征 。 在简述小波包基本原理的基础上, 通过仿真信号, 对振动信号的具体处理过程进行分析, 并对可能遇到的问题, 提出处理办法, 然后应用于诊断实例 。 (Early damage fault for rolling bearings and other gear, the proposed wavelet packet decomposition as pre-processing means envelopment analysis to extract characteristic vibration signal fault information. On the basis of the basic principles outlined wavelet packet, through simulation signal processing for specific vibration signals are analyzed, and the problems that may be ncountered, proposed approach, and then applied to the diagnosis example.)

meanshift图像分割
1.mean shift 的迭代过程只做了一次(为了简单)
2.对图像中的某一点进行平移时,只考虑了距离它小于2*hr的点,而不是图像中所有的 点。
3.实验过程中只用到了gauss核,虽然提供了method的选择,但在进行值域加权时只用 到gauss核,如果需要请自己改正。(meanshift segmentation)

QualityGuidedUnwrap2D_r1
基于matlab实现干涉显微镜图像重构中的二维解包裹函数。( QualityGuidedUnwrap2D implements 2D quality guided path following phase
unwrapping algorithm.
Inputs: 1. Complex image in .mat double format
2. Binary mask (optional)
Outputs: 1. Unwrapped phase image
2. Phase quality map
This code can easily be extended for 3D phase unwrapping.
Technique adapted from:
D. C. Ghiglia and M. D. Pritt, Two-Dimensional Phase Unwrapping:
Theory, Algorithms and Software. New York: Wiley-Interscience, 1998.

第五次作业
说明: 1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换,并显示其频谱,用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。(提示:显示频谱时,可以先对频谱取对数,这样可以压缩动态范围很大的频谱,获得更好的显示效果)(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))
