2) double thresholds
双重阈值
1.
In this paper,the authors put forward an approach to extract fetal heart signal based on coif5 wavelet transform and double thresholds.
由于胎心多普勒信号具有信噪比低、非平稳的随机性特点,提出基于coif5小波,结合双重阈值方法的胎心音信号提取算法。
3) threshold denoising method
阈值去噪重构
4) overlap block complex threshold
重叠块复阈值
1.
And the relationship of coefficients of wavelet packet is considered,and overlap block complex threshold algorithm is proposed.
同时考虑小波包系数之间的相互关系,提出了重叠块复阈值算法。
