Paper Abstract

The direct binary search (DBS) algorithm is one of a family of iterative approaches to signal design. DBS is characterized by a particular search strategy and an efficient approach to evaluating the effect of trial changes. From its origins as a method for synthesis of digital holograms, we trace the evolution of DBS to its current state as a powerful and flexible method for digital half toning and a tool for development of derivative algorithms for digital half toning. We describe the theory that underpins how DBS behaves, and discuss in some detail the use of printer models within DBS. Finally, we describe briefly the application of DBS to color half toning and its use to design halftone screens. A lookup table based algorithm, aperiodic micro screens, and halftones with an embedded watermark.
