ABSTRACT
This chapter provides the theory of point process statistics and extend them to discrete-space for use in characterizing the spatial arrangement of minority pixels within a binary dither pattern. The pair correlation may, therefore, be insufficient, by itself, at describing binary dither patterns uniquely when patterns are allowed and even preferred to be anisotropic. Stochastic geometry is the area of mathematical research interested in complex geometrical patterns. Spectral analysis was first applied to stochastic dither patterns by Ulichney to characterize dither patterns created via error-diffusion. The chapter discusses halftone visibility, showing how a model of the human visual system is used to measure the differences seen by a human viewer between an original continuous-tone image and a binary halftone. In understanding the process of color reproduction, it is important to have an understanding of the human visual system and how the eye sees color.
