7.4.7 Find Edge Width
This tool finds edges, and measures spacing between two edges in accordance with ROI direction.
Parameter Settings
Filter Kernel Half-Width
It is used to enhance the edge and suppress noise, and its min. 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 parameter value needs to be set based on
the actual situation.
Contrast Threshold
It is also called gradient threshold, and its range is from 0 to 255. The edge point whose gradient
threshold is larger than this value can be detected. The larger the value, the stronger noise
resistibility, the smaller the number of edges obtained, and even the target edge points are
filtered out.
Edge 0 Polarity
The polarity of the first edge point. It includes White to Black, Black to White, and All.
Edge 1 Polarity
The polarity of the second edge point. It includes White to Black, Black to White, and All.
