How to reduce the noise at Point Cloud data?

Hi all.

I'm processing the Point Cloud data with the OpenCV Viz library.

I have Point cloud data, but it has a lot of noise. So, I want to reduce noise.

But I don't know how to apply the Low Pass filter or Median filter.

Could you please let me know how to apply the filter at the Point Cloud?

Thank you. :)

Your question is off topic if you use pointcloud for computing stereo correspondence. Which algorithm do you use to match image?

I don't use Point Cloud to match image. I'm scanning the object with the 3D scanner(Laser triangulation type). Just get raw data from the 3D Scanner and convert to Point Cloud.
