Paper Abstract

We propose an arithmetic coding model for color images processed by the error diffusion. The error diffusion is a dynamic thresholding method of high quality tone rendering. However, there is a problem that probability model of conventional compression methods such as MH and MMR are not suitable for bi-level images processed by the error diffusion. Consequently, much transmission time or much accumulation memory is required. We have constructed a probability model which is based on the processing structure of the error diffusion, and combined arithmetic coding because of its flexibility in the construction of probability models. Simulation results have shown that this coding model is efficient for color images processed by the error diffusion.
