Dear Web Surfer;

This website was first assembled in the summer of 1998 to draw attention to the halftoning research that I was doing at the University of Delaware while earning my Ph. D. in Electrical Engineering. The work that I was doing then focused exclusively on green-noise halftoning where the illusion of continuous-tone is produced in binary display devices using a stochastic arrangement of clustered dots.

Since the first published work, "Green-Noise Digital Halftoning," was published in the proceedings of the IEEE's 1998 International Conference on Image Processing (ICIP), my work has resulted in six journal papers including an article in the December 1998 issue of the Proceedings of the IEEE, two patent applications filed by the University of Delaware, nine conference proceedings papers, one Ph. D. dissertation, and the book Modern Digital Halftoning by Marcel Dekker Inc.

Today, the work is far more diverse with our introduction of stochastic moiré, the fluctuation in texture created by two overlapping stochastic dither patterns, and with new approaches to digital watermarking. But I haven't forgotten my past as I am still in the process of developing green-noise and green-noise masks for color printing applications.

With this letter, I invite you to further browse our website for more information regarding our work at Kentucky. Please enjoy this site as it is for your benefit that we host it.

Sincerely,


Dr. Daniel Leo Lau
