RemoveSmallSpots

Removes the smallest objects of a binary image.

Access to parameter description

This algorithm removes spots smaller than a user-defined size in a binary image.
The objectSize parameter indicates the maximum size, in pixels, of the spots to be removed.

In order to remove the small spots, this algorithm amounts to filtering the image with: See also
