ABSTRACT
Digital color halftoning is the process of transforming continuous-tone color images into images with a limited number of colors. The importance of this process arises from the fact that many color imaging systems contain output devices, such as color printers and low-bit-depth displays, that are bilevel or multilevel with only a few levels. The goal is to create the perception of a continuous-tone color image using the limited color discrimination capability and the lowpass characteristics of the spatial sensitivity of the human visual system (HVS).
