Reducing the Complexity of Multiscale Error Diffusion
Multiscale error diffusion (MED) is superior to conventional error diffusion algorithms as it can eliminate directional hysteresis completely. However, the complexity of this frame-oriented process is much higher and makes it not suitable for real-time applications. In this paper, a fast MED algorithm is proposed. The complexity of this algorithm is remarkably reduced as compared with conventional MED algorithms. It also supports parallel processing
