Abstract
New implementations of error diffusion algorithms are proposed. These methods replace the complex, real time computations with a series of table lookups and a summation. They lower the computational cost and increase the processing speed. Implementation details are given in this paper. These implementations make the level-dependent error diffusion possible that an optimal error filter is used for a certain range of tone levels. Other advantages of these methods are also discussed.
