Abstract
Dithering with blue noise mask has no artifact as the error diffusion and it is very simple to implement. But it does not represent well the local property of edges. In this paper, a local adaptive masking technique is proposed. By controlling the local adaptive factors, the amount of high pass filtered and blue noise components are controlled. It was shown that the proposed algorithm has similar effects on simple threshold in background, blue noise masking in mid- level and high pass filtering in edge regions. The resulting image shows good gray-tone reproduction as well as good edge characteristic.
