8.6.1 Find Contours (base)

The filter finds borders of the objects at black and white images, which allows to select different objects.

The filter is applied right after the image processing with the threshold transformation and is a part of the composite filter for searching contours.

Filter parameters:

  • Show one the source image (ShowOnSource);
  • Size of approximation (approximateSize);
  • Minimum perimeter (minPerimetr);
  • Maximum perimeter (maxPerimetr).

The Show one the source image (ShowOnSource) parameter shows contours in the source image. Size of approximation (approximateSize) — is approximation (rounding) of size. Minimum perimeter (minPerimetr) — minimum value of particle perimeter. Maximum perimeter (maxPerimetr) is a maximum value of the particle perimeter.


Altami software products work under the most popular modern operating system such as Windows, Linux и Macintosh.
