FIGURE 3.17: Different error diffusion schemes
Other error diffusion schemes are possible; two such schemes are Jarvis-Judice-Ninke
and Stucki, which have error diffusion schemes shown in Figure 3.17.
They can be applied by modifying the Floyd-Steinberg function given at the end of the
chapter. The results of applying these two error diffusion methods are shown in Figure 3.18.
