Remarks

The filter represents binarization filter, which is based on error diffusion dithering with Stucki coefficients. Error is diffused on 12 neighbor pixels with next coefficients:

        | * | 8 | 4 |
| 2 | 4 | 8 | 4 | 2 |
| 1 | 2 | 4 | 2 | 1 |

/ 42

The filter accepts 8 bpp grayscale images for processing.

Sample usage:

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

Initial image:
