Adjusting the Edge Level
In an ECM search, processing is executed on the edge extraction image. Change this item as necessary
when the edge is not extracted or is extracted along with noise.
Important
In model registration, extract as much of the edge as possible, then delete noise etc. in the mask registration to
●
register the entire edge of the model. On the other hand, when measuring, even if the edge has skips, an image
with the noise suppressed makes it possible to search the model stably. To set separate edge extraction
conditions for model registration and for measuring, after registering the model, change the edge extraction
conditions.

FZ3 Processing Items List Manual
Select the range of pixels which are used to extract the edge. With a
larger mask size, search is less affected by variation in pixels.
Adjust the edge extraction level when the edge is hard to see due to
low contrast with the background or when unnecessary background
noise should be removed.
