Perfect segmentation

[feersantana5]

I have done this tutorial https://towardsdatascience.com/how-to-automate-3d-point-cloud-segmentation-and-clustering-with-python-343c9039e4f5 to get better performance using DBSCAN method. However with my own pics I can't get a perfect segmentation as this man does.

Using only DBSCAN method i get:

After the tutorial I get:

I would like to be able to extract the chair using segmentation. Any trick? or parameter I should change?

Hey, DBSCAN is sensitive to parameter settings that depend on your scene:
min_pts and eps

Please check the DBSCAN paper or the Wikipedia article for help on setting these parameters.
