=== Basic Parameters === 


**Ground From Trajectory**\\
Relative position of the ground to trajectory. Ground height is defined by trajectory height. 

**Search Slice Height Min**\\
Minimum height of the slice to get the trunks.

**Search Slice Height Max**\\
Maximum height of the slice to get the trunks.

**Grid Cell Size**\\
The size of a cell in the scanning grid. 

**Grid Cell Pts Min**\\
Minimum number of points required in a scanning grid cell within the search slice. 

**Histogram Cell Size**\\
The size of a cell within the histogram grid. These cells are used to identify density peaks on the horizontal slice to get the trunks.

**Histogram Cell Pts Min**\\
The minimum number of points in a histogram cell, within the search slice height min and max. To make it count as possible trunk.
 
**Trunk Diameter Max**\\
The maximum diameter for a trunk.

**Distance Between Trunks Min**\\
The minimum distance between two trunks of two different trees to be detected.
