Understanding the Window and Skip Settings
The Bridge Value tool measurements use a histogram of the ranges that make up the profile. The
Window and Skip parameters together determine what segment of the heights in the histogram is used
to calculate the bridge value. The following diagram illustrates what points of a histogram would be
included for calculating the bridge value where
Window is roughly 85% and Skip is roughly 15% of the
histogram.
Profile point heights in the white area are included in the calculation of the average. Profile point heights
in the grey area are excluded. By adjusting the
Window and Skip parameters, you can exclude profile
point heights that correspond to unwanted features on the target. In road roughness applications, for
example, you could exclude rocks, cracks, tining valleys, and so on, to get an accurate representation of
the tire-to-road interface.
