Compared with the traditional thresholdfunctions, the improved one was more advantageous in ultrasonic signal denoising.
相对于经典的阈值函数,改进的阈值函数在超声信号去噪中更具有优势。

The corresponding nonlinear thresholdfunctions (bivariate shrinkage function) are derived from the model using the Bayesian estimation theory.
基于贝叶斯估计理论,得到了相应的非线性阈值函数(双变量收缩函数)。

As for non-threshold function, a novel logic synthesis algorithm is proposed, which can transform non-threshold function to the sum of some thresholdfunctions.
