ABSTRACT: In mobile environment, a low-complexity is
the significant feature because the mobile device has very limited resources
due to power consumption. In this paper, we propose a low-complexity
watermarking scheme for mobile device. We apply the minimum average correlation
energy Mellin radial harmonic (MACE-MRH) correlation filter to watermark
detection. By the scale tolerance property of MACE-MRH correlation filter, the
proposed watermark detector can be robust to scaling attacks. Empirical
evidence from a large database of test images indicates outperforming performance
of the proposed method.
