An Innovative Pixel Scoring Method for Watermarking of Binary Document Images

Abstract

In order to embed a watermark into a binary document image, some subset of image pixels needs to be modified. This modification will cause a document image distortion. Careful selection of image pixels can make distortion appear less visible. We propose a new binary document image pixel scoring method, the Structural Distortion Measure, whose objective is to identify image pixels whose modification, as part of a watermark embedding process, will minimize document image visible distortion.

A Improve Robust Watermarking Algorithm for Binary Images

“…It is very challenging to undetectably embed information into a binary image. In recent years, with the development of binary images watermarking, there were a few methods being proposed, such as spatial domain [1] [2], wavelet transform domain [3] [4] and specific format document [5]. More than that, some of them put forward many good suggestions on enhancing capacity [6], developing robustness [7] and improving security [8] for binary images.…”
