| Abstract(in English) | Motivated by digital halftoning application to convert a countinious-tone image into a binary image, we discusses how to round a real valued matrix into a binary matrix achieving low discrepancy with respect to the family of all 2×2 square submatrices. In this paper we give a more simple algorithm than known ones and report experimental results. |
