Abstract :
A digital halftoning method is proposed based on a multiscale error diffusion technique for digital halftoning. It can improve the diffusion performance by effectively removing pattern noise and eliminating boundary and "blackhole" effects. A dot overlap compensation scheme is also proposed to eliminate the bias in the gray scale of the printed images.
