Abstract
This paper proposes a zero watermarking algorithm using new Hu invariant moments. It combines the features of Hu invariant moment and few of new invariant moments to form a more complete feature vectors. This method maintained the original Hu moment translation, scaling and rotational invariance of original Hu invariant moments, but also contain more detail information than the original Hu invariant moments. The algorithm through a series of adding noise, filtering and JPEG compression simulation, The results show that the algorithm of the conventional signal processing and geometric attacks is better robustness than the original seven Hu moment invariants have some improvement.关键词
