Additional procedures which can be executed at the finalization stage.
Remove markers. Use this procedure only when the scanning was made in
marker tracking mode. Put a tick against Remove markers and choose marker
radius in order to remove it from object geometry. This parameter can vary
depending on the model of your scanner, as well as on marker type: markers
can be both magnetic and printed by you on the printer.
Markers are not removed on the texture

The algorithm automatically identifies all markers on the surface, removes
them and fills newly formed holes. If markers are in areas of the surface with
nonuniform geometry, the holes may be filled incorrectly. Therefore, when
placing markers, it is recommended not to overrun the perimeter of an ob-
ject, as well as to avoid an area with significantly large geometry.
Filtering by size. The filtering algorithm removes noise and extra objects
which could fall into the field of scanner vision in the process of scanning.
When the Leave the biggest part option is chosen all smaller objects as com-
pared to the largest one will be removed. When the Remove parts smaller
than option is chosen the algorithm will remove objects that are smaller in
size than the selected value (in polygons).
