Running Parameter
Edge Mode: it includes single edge and edge pair modes.
- Single edge mode detects the edge position in the specific area and can be
used to locate, count and verify the presence or absence.
- Edge pair mode detects edge spacing in a specific area.
Filter Size: it is used to enhance the edge and suppress noise, and its minimum value is 1.
When the edge is blurred or there is noise interference, you can increase its value to make the
detection result more stable. If the distance between the edge and the edge is smaller than the filter
size, it will affect the accuracy of the edge location or even lose edge. This value needs to be set
based on the actual situation.
Edge Threshold: The edge threshold is the gradient threshold, ranging from 0 to 255. Only
edge points whose edge gradient threshold is greater than this value are detected. The larger the
value is, the stronger the anti noise ability is, the less the number of edges is, and even the target
edge points are screened out.
Edge Polarity: it has three modes, including dark to light, light to dark and both.
Edge Pair Width: it means that the size of the pixel spacing of the edge pairs that are
expected to be output. Adjusting this parameter separately cannot directly screen out the expected
edge pairs. Only when one or more score methods, including current position normalization score,
relative position normalization score, space score, space gap score and relative space gap score, are
enabled, adjusting this parameter is meaningful.
Max. Result Number: it is the maximum number of edge pairs expected to be output. If
the logarithm actually found is greater than this parameter, the edge pair of this parameter is output
according to the score from high to low. Otherwise, the actual edge pair quantity is output.
Sort Method: score ascending, score descending, direction forward and direction reverse.
The results are sorted according to the selected type.
Projection Direction: it includes from top to bottom and from left to right.
