Applying median filtering will effectively reduce the impulse noise, which can combine waveletpacket transform and median filter.
将子波包变换和中值滤波相结合，可以有效地降低图像噪声。

In traditional denoising methods for signals, we usually use the method of threshold to achieve denoising by the threshold disposing of waveletpacket transform.
传统信号去噪方法常采用门限法对噪声信号的小波或小波包变换做阈值处理以达到去噪的目的。
