connected_components

Assigns an ID to each cluster of connected components in a point cloud. The point cloud is subdivided
into a 3D grid, and a classical Connected-Component Labeling algorithm is applied in 3D.

Airborne LiDAR (Light Detection and Ranging) interface for data
manipulation and visualization. Read/write 'las' and 'laz' files, computation
of metrics in area based approach, point filtering, artificial point reduction,
classification from geographic data, normalization, individual tree segmentation
and other manipulations.

connected_components function

<dl><dt>las</dt>
<dd>A LAS object representing the point cloud data.</dd>
<dt>res</dt>
<dd>Grid resolution. If two non-empty voxels are contiguous, they are considered part of
the same component.</dd>
<dt>min_pts</dt>
<dd>Minimum number of points in a cluster. If a cluster contains fewer than <code>min_pts</code>
points, it is assigned an ID of 0, indicating that it does not belong to any group.</dd>
<dt>name</dt>
<dd>A string specifying the name of the new attribute used to store the ID of each cluster.</dd>
<dt>connectivity</dt>
<dd>integer. 6, 18 or 26 neighbors search.</dd></dl>
