Is this method removing noise or smoothing the pointcloud

Dear @chenhonghua ,

Many thanks for this great work.

I have concern about how you define the task.
I have some concerns regarding how the task is defined in the RePCD-Net paper. From my understanding, it appears to be more of a smoothing approach for a corrupted 3D point cloud.

My question is that can this method actually remove points which are considered noise

For example, I have a pointcloud in which the red points are noise:

Can RePCD Net remove and output ,as I consider, a noise-free pointcloud like this:

Please take a look, I look forward to your reply.

hi, I observe that the red noise is kind of more like outliers.
I think RePCD-Net cannot well remove them. As for the outlier removal, this task could be defined as a classification problem. Maybe we can train a network to predict a label (outlier or not) for each point.
