Analysis of threshold modulations in one-dimensional error diffusion

Error diffusion is a numerical method for the binarization of continuous tone data. Modified error diffusion algorithms exist that introduce threshold modulations into the process. this article generalizes an analytical model of error diffusion to include those threshold modulated algorithms. The ag...

Description
Summary:Error diffusion is a numerical method for the binarization of continuous tone data. Modified error diffusion algorithms exist that introduce threshold modulations into the process. this article generalizes an analytical model of error diffusion to include those threshold modulated algorithms. The agreement between analytical prediction and the result of numerical error diffusion is shown.
