I have a point cloud representing top view of two nearby objects. Performing segmentation using pcsegdist identifies them as one segment. I feel like I would be able to separate them into two objects after applying erosion. How can I achieve erosion in pointclouds?

Thanks!

Transform the point cloud into an image, then you can use Matlab image processing tools and functions.

A quick search on the File Exchange lead me to this function, but I have not tested it myself.

@DGM This can be useful if we can convert the point clouds into voxel/grid representation. If you have any ideas about conversion from point clouds to voxel/grid, you may share here.
