L filter,multistage L filter,and the filter combined L filter with curvature flow filter through many iterations,could filter image noise of higher, middle,and lower SNR level respectively.

提出了L-曲率流滤波器的图像降噪(滤波)算法,该方法按图像信噪比大小分高、中、低3类,分别由L滤波器降噪、多级L滤波器降噪以及多次迭代的组合滤波器降噪,并进行了实验研究。

The real-time problem existed in the application of L filter in background suppress is solved.

提出了一种基于图像局部统计特征的自适应背景抑制算法,给出了一种近似估计图像噪声方差的方法,解决了L滤波在背景抑制应用中实时性的问题。

Afterwards, we make K-L filtering to the data, then the signal-noise ratio of seismic data is improved greatly.

之后又对记录进行了K-L滤波,从而大大地提高了地震记录的信噪比。
