I have attached a 3D point cloud here . You can call the function using:
DisplayReconstructedScene( RimPointCloud_filt_lst_sq, J1 );
It looks like this:
How can I process this further and remove all noise? I want only the circular object's surface to be detected. Kindly let me know if further information is required. I want to remove those tiny groups of data points which are away from the main data points.
I have already tried pcdenoise. It didn't show any difference to my results.

Yea, pcdenoise did not help me, even after trying various parameters. I had to write a custom code. However, it would be easy if I knew this .

Maybe too late but someone need for answer.
Latest Matlab has Point cloud processing toolbox.
pcdenoise function will suit for your work. But you need to change parameters for neighbor and sigma threshold.
ptCloudOut = pcdenoise(ptCloudIn)
cheers.
