This algorithm makes use of lowpass filter and coring circuit to suppress small noise; utilizes adaptive clamping to eliminate ringingeffect and "wrong colours".
From the experimental result, this new algorithm can give better results than classic Wiener filtering with little ringingeffect on the image border and little vibration on the edge.
实验结果显示，较之经典的维纳滤波恢复结果，新算法能够更好的消除边界的振铃和图像边缘的振动波纹。

An image restored by a recursive solution of traveling wave equation is natural to visual interpretation, without ringingeffect and distortion emerging, but accumulated noise appears on it obviously.
