Paper Abstract

Algorithms are investigated for the printing or display of color images at near original image quality with a minimum number of output colors. Each algorithm consists of a quantizer possibly used in conjunction with haiftoning. We consider both image independent and image dependent quantizers implemented in RGB or in the uniform color space L*u*v*. The halftoning techniques that we use are multilevel extensions of error diffusion and ordered dither. Image quality resulting from use of these algorithms is measured by subjective evaluation.
