Request for advise about DoN segmentation

[jhyim5589]

First of all, thank you for share your great work and sharing data.

This repo gives me a lot of inspiration and i have tried it with my rosbag log file.

Since our data is from VLP16, our LiDAR coverage is too short.(Points' sparsity)

So I have tried several clustering methods that this repo offering(REC, EC, RG and DoN)

In my opinion(I have just check through my eyes), Distance of Normals methods offer slightly better clustering for farther points.

What I'm asking is that are there any materials that I could refer to, since I have no knowledge about DoN methods.

Hope you could give me an advise. Thank you so much

Sincerly,
