Dithering using Burkes error diffusion.

The filter represents binarization filter, which is based on error diffusion dithering with Burkes coefficients. Error is diffused on 7 neighbor pixels with next coefficients:

| * | 8 | 4 | | 2 | 4 | 8 | 4 | 2 | / 32

The filter accepts 8 bpp grayscale images for processing.

Sample usage:

// create filter BurkesDithering filter = new BurkesDithering( ); // apply the filter filter.ApplyInPlace( image );
