摘要
对小波变换理论知识做了简要介绍,并详细的分析了小波阈值去噪方法的原理和实现,分析了传统阈值函数去噪方法的优缺点,提出改进阈值函数。最后结合理论分析和实验实例得出改进阈值函数相比与传统的阈值函数在多阈值选取小波信号去噪方面具有更好的光滑性和相似性。
Do a simple introduction of Wavelet transform theoretical knowledge, and a detailed analysis of the wavelet threshold denoising method and the implementation of the principle, analysis of the traditional thresholding function denoising method of the advantages and disadvantages, made an improved-threshold function. Combination of theoretical analysis and experimental examples it comes that the improved-threshold function compared with the traditional threshold function in wavelet signal denoising area with better smoothness and similarity.
