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.

noise should be removed.
