Watermarking Method by Alternative Representation of Document Backgrounds

Abstract (in Japanese) (See Japanese page) 
(in English) When a digital watermark is embedded in a document image, the watermark patterns are interfered with by the background element of the document, resulting in deterioration of the watermark quality. This paper proposes an alternative representation of document backgrounds by a watermark to decrease the deterioration, in which the background element is separated from the document image, and the watermark is embedded to represent the characteristic of the backgrounds. To represent the background element, the dot size of the watermark is changed from the basic dot patterns, preserving the characteristics of the watermark.
