滤波过程中，根据噪声记录数组的信息，剔除噪声点周围的其它噪声点的灰度信息，使噪声点的灰度值得到较好的还原。

In course of filtering, it can get rid of other noise points round the noise point being filtered with the array.

包括了最佳维纳滤波反褶积与窗函数滤波反褶积对于背景电导率信号还原的处理方法。

In these methods, we use the optimum Wiener filtering and Window filtering deconvolution technique to process the background conductivity signal.
