• 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 polarities, including dark to light, light to dark and any.
• Edge Type: it includes strongest edge, last edge, first edge and all.
• Find Direction: it includes top to bottom and left to right.
• Min. Edge Score: find the minimum score of the edge. The edge with a score lower than
the minimum score will be filtered out.
• Max. Result Number: maximum number of searching.
• Sort Method: score ascending, score descending, direction forward and direction reverse.
The results are sorted according to the selected type.
Position Correction
The tool of position correction is used to assist positioning and precise positioning, and modify
target motion deviation. It establishes the reference of position deviation according to match points
and match frame angle in the template matching result, and then realize ROI coordinate rotation
deviation of detection box according to the relative position deviation of running point and fiducial
point in the template matching result, as shown below.
