Title:
   Error diffusion: recent developments in theory and applications 

Speaker:     Chai Wah Wu, IBM T. J. Watson Research Center

Abstract:

Error diffusion is a popular technique for digital halftoning.
The purpose of this talk is to illustrate the versatility of error
diffusion with applications beyond halftoning and to show its connection
to deep mathematical questions.  I will present some recent developments
in the theory and applications of error diffusion and related algorithms.
In particular, I will present several stability results of error diffusion
and show applications in a variety of areas besides image halftoning
including scheduling, image watermarking and data hiding, and image
enhancement in LCD displays.
