EC Circle Search

Measurement Parameters
This processing item searches the input image for parts having a high degree
of similarity to the target circle mark (model), and measures its circle evalu-
ated value (similarity) and position.In a normal search, image pattern models
are used that look at the color and light/dark information. In EC Circle Search,
however, models are used that look at the profile.Therefore, this processing
assures a reliable search even for low-contrast or noisy images.It is also pos-
sible to measure the number of circles in the input image.
• This counts how many circles there are of the specified size.Since circles
are extracted using the shape information in „Round", the circles being
deformed or dirty does not affect counting.
