Abstract: This paper presents a color image error diffusion method based on MBVC with adaptive filtering. It points the problem that exists in the MBVC method using fixed error diffusion coefficients leads to “directional artificial texture”. This method intelligently amends filter coefficients by using adaptive way. The Minimal Brightness Variation Criterion is dealt to get halftone results. It can reduce color noise because of the difference between each color. The experimental results show that this algorithm can get better visual quality than the previously published known results.

Key words: Minimal Brightness Variation Criterion（MBVC）, adaptive filtering, error diffusion, mean squared error
