摘要
Higher quality is obtained with error diffusion algorithms such as the Floyd Steinberg error-diffusion algorithm used in halftoning methods in which quantization errors are diffused to "future" pixels, by adding a Minimum Brightness Variation Criterion (MBVC) to the design rules of color error-diffusion halftoning methods. Halftone values are constrained to be vertices of a Minimum Brightness Variation Quadruple (MBVQ) associated with each pixel of the color image being processed.
