- 这是一个简单的高次逼近函数的函数图像,它可以作为去噪的阈值函数,在阈值处是连续的。函数中的n值可以自己任意设置。还有几个阈值函数和阈值,在小波变换的每一层上选择不同的阈值-This is a simple high-order function of the approximation functions of the image, it can be used as a threshold function of de-noising,The function is continuous a

- 小波阈值自动选取方案去噪,并用HHT对去噪后的轴承信号进行处理,提取故障特征。-Wavelet threshold de-noising program automatically chooses, for bearing with HHT denoised signal processing, fault features.
