public class BinaryDilatation3x3 : BaseUsingCopyPartialFilter


The filter represents an optimized version of Dilatation filter, which is aimed for binary images (containing black and white pixels) processed with 3x3 structuring element. This makes this filter ideal for growing objects in binary images – it puts white pixel to the destination image in the case if there is at least one white neighbouring pixel in the source image.

See Dilatation filter, which represents generic version of dilatation filter supporting custom structuring elements and wider range of image formats.

The filter accepts 8 bpp grayscale (binary) images for processing.
