A new filter algorithm named K neighborhood adaptive filter is proposed here for smoothing strong impulsedisturbance in the difference image.
针对运动景物在差分图像中产生强脉冲干扰的特点，提出K邻域自适应滤波算法；

The control quality indexes under the same optimal PD parameters and the different integral time set by the different weighted factor are compared and the impulsedisturbance analyse is given.
比较在相同优化PD参数和按不同加权因子整定优化积分时间的控制品质指标并进行脉冲扰动分析。
