Label Connected Components : keep unconnected points

[ThomasRisto]

Hello !

I've been using the Label Connected Components segmentation and I realised that once the segmentation is done, the points that were not clustered just disappeared.

I figured out a trick (merging clusters + distance with the original cloud + threshold) to get them back, but it should not be very difficult to have the algorithm save the remaining points in a last cluster...

That would be very useful if I want, for example, to perform another segmentation with other parameters on these points...

Thanks again for listening to the community !

If you don't want to lose any points you can simply set the 'Min points per component' to 0 (instead of 10 by default).

Then the components are sorted by size, so you can easily get the smallest (at the end) and merge them.

Thanks for the hint, I'll do that
