Removing high frequency noise pulses by a low-passfilterand Schmitt-trigger.
用一低通滤波器和施密特触发器排除高频噪声脉冲。

The traditional low-passfilter method can restrain the high frequency part and decrease noise but may destroy image detail, and other methods also have other defects.
传统的低通滤波方法将图像的高频部分滤除,虽然能达到降低噪声的效果,但会破坏图像的细节。

The proposed architecture adopt recursive pyramid algorithm(RPA)instead of the classical pyramid algorithm(PA), only one low-passfilterandhigh-pass filter are required to compute all levels.
