RemoveSmallHoles

Fills the smallest holes of a binary image.

Access to parameter description

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

In order to fill the small holes, this algorithm amounts to filtering the complement of the input image with: See also
