Hybrid watermarking for improving detector performance

Published: 23 October 2006 Publication History

Abstract

In this paper, we describe the adaptive hybrid watermarking scheme to improve the watermark detector's performance. In the hybrid watermarking, the conventional spatial watermarking and QIM scheme are applied simultaneously to the spatial domain of the image. According to the edge-map of the image the spatial watermarking is applied to the flat region and the QIM is applied to the high frequency region including edge and texture. The threshold between flat and edge is decided empirically and watermark blocks are embedded repeatedly into the image. In the detection process, we show how to estimate the threshold value by ACF(Auto-Correlation Function). Experimental results show the proposed hybrid watermarking estimates the watermark signal correctly than the conventional spatial watermarking.
