Remarks

The filter allows to fill black holes in white object in a binary image. It is possible to specify maximum holes' size to fill using MaxHoleWidth and MaxHoleHeight properties.

The filter accepts binary image only, which are represented as 8 bpp images.

Sample usage:

Copy
// create and configure the filter
FillHoles filter = new FillHoles( );
filter.MaxHoleHeight = 20;
filter.MaxHoleWidth  = 20;
filter.CoupledSizeFiltering = false;
// apply the filter
Bitmap result = filter.Apply( image );

Initial image:
