Abstract
Among the various digital halftoning methods, carrier procedures have the advantage of being fast and requiring few computational resources. However, because they are pixel-oriented algorithms, they offer less flexibility than more complex algorithms that involve the information from a neighborhood or the entire image in the quantization of each pixel. By introducing noninteger ratios between the carrier and raster period, the carrier procedure can be adapted to the spectral characteristics of the visual system. The spectral noise distribution can be optimized in this regard for two-dimensional, periodic carriers with arbitrary shape.
