Running Parameter
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 any.
Widest: represents the edge pair with the largest spacing within the detection range.
Narrowest: represents the edge pair with the smallest spacing within the detection range.
Strongest: represents the edge pair with the largest average gradient within the detection
range.
Weakest: represents the edge pair with the smallest average gradient within the detection
range.
First Pair: represents the edge pair whose center of the edge pair within the detection range
is closest to the starting point of the search.
Last Pair: represents the edge pair whose center of the edge pair within the detection range
is furthest to the starting point of the search.
Closest: represents the set of edge pairs closest to the ideal width within the detection
scanning range.
