Median
The Median filter substitutes the value of a data point with the median calculated within a specified
window around the data point.
Missing data points will not be filled with the median value calculated from data points in the
neighbourhood.
To configure X or Y median:
1. Go to the Scan page.
2. Choose Profile or Surface mode in the Scan Mode panel.
If one of these modes is not selected, you will not be able to configure the median filter.
3. Expand the Filters panel by clicking on the panel header or the button.
4. Click on the Median tab.
5. Enable the X or Y setting and select the maximum width value.
6. Save the job in the Toolbar by clicking the Save button .
7. Check that the laser profiling is satisfactory.
Smoothing
Smoothing works by substituting a data point value with the average value of that data point and its
nearest neighbors within a specified window. Smoothing can be applied along the X axis or the Y axis. X
smoothing works by calculating a moving average across samples within the same profile. Y smoothing
works by calculating a moving average in the direction of travel at each X location.
If both X and Y smoothing are enabled, the data is smoothed along X axis first, then along the Y axis.
Missing data points will not be filled with the mean value calculated from data points in the
neighbourhood.
