On the Relation between DBS and Void and Cluster
Abstract:In this paper we compare and contrast two well known approaches for designing screen functions: direct binary search (DBS) and void and cluster (V&C). They are both iterative, search based methods that minimize a metric of error between the perceived halftone and the perceived continuous-tone original image. Despite the many differences between these two approaches, these is a close correspondence between them. In this paper, we will explore these links in detail, and examine their implications for the performance of both algorithms.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
