利用小波变换，EMD以及两者的综合分别进行轴承信号背景噪声去噪分析-Using wavelet transform, EMD and the combination of the two separate bearing signal denoising of background noise

一些matla实现的图像处理算法，有emd,和BEMD分解的程序，及图像去噪等算法。-Some matla realize image processing algorithm, emd, and BEMD decomposition process, and image denoising algorithm.

三种emd去噪方法：1、直接使用小波阈值，进行硬阈值去噪；2、使用具有emd分解特性的阈值去噪；3、emd分解后的平移不变去噪。(Three kinds of EMD denoising methods: 1. Direct use of wavelet threshold for hard threshold denoising; 2. Use of threshold denoising with EMD decomposition characteristics; 3. Translati
