[Waveletwavelet_function

Description: 常规小波阈值去噪方法是在假定小波系数独立的条件下进行处理的,没有考虑到小 波系数在相邻尺度上的相关性.因此,也同样受到去噪和保留有用高频信息两难的困扰-Conventional wavelet thresholding denoising method is the assumption that the wavelet coefficients under the conditions of an independent deal with, and does not take into account the wavelet coefficients in adjacent scales of relevance. Therefore, it will also be useful by the de-noising and retain high-frequency information dilemma problems
