Application of New Hu Invariant Moments in Zero Digital Watermarking
摘要
Abstract
This paper proposes a zero watermarking algorithm using new Hu invariant moments. It combines the features of Hu invariant moment and a few of new invariant moments to form a more complete feature vectors. We can use the feature vectors to construct zero watermarking system more effectively. This method can be used to achieve more accurate object recognition in pattern recognition field and it can also be used to achieve retrieval performance more perfectly than original Hu invariant moments in image retrieval field, meanwhile. It can not only maintain the translation, scaling and rotational invariance of original Hu invariant moments, but also contain more detail information than the original Hu invariant moments. Accordingly it can describe the image more fully. Therefore this method can improve the robustness and credibility of watermarking system efficiently using the new invariant moments and original seven Hu invariant moments.关键词
