RST resilient multi-bit image watermarking based on BITPLANE centroids

Abstract

How to efficiently resist geometric attacks remains a challenging direction in watermarking research. In this paper, a multi-bit image watermarking scheme based on image centroids is presented. Some measures including adaptive low pass filter, finely tuning the partitioning are used to further improve the performance. The experimental results show that the scheme can achieve high capacity as well as good robustness against rotation, scaling and translation (RST) attacks and considerable robustness against typical image processing.
