To calibrate the counting line:
Select the counting line with the mouse.
Check the "Enable Calibration" box under the “Object Crossing Line A/B” rule in the
Analysis properties.
Use the mouse to drag the calibration markers to adjust the distance between the
calibration markers until the distance is approximately the size of the objects to be
counted.
The small markers on either side of the big markers indicate the minimum and
maximum width which is counted as a single object.
Apply the settings.
Shadow Filter
The counting line features a shadow filter which is designed to remove the effects of object
shadows affecting the counting algorithm. Shadows can cause inaccurate counting results by
making an object appear larger than its true size or by joining two or more objects together.
If shadows are causing inaccurate counting, the shadow filter should be enabled by selecting
the "Enable Shadow Filter" check box for the line. It is recommended that the shadow filter
only be enabled when shadows are present because the algorithm can mistake certain parts
of an object for shadows and this may lead to worse counting results.
