On the implementation of a digital watermarking based on phase congruency

Abstract

In this paper a human visual system (HVS) model guided least significant bit (LSB) watermarking approach for copyright protection is proposed. The projected algorithm can embed more information into less featured surrounded areas within the host image determined by phase congruency. Phase congruency offers a dimensionless quantity which is an excellent measure feature points with high information and low in redundancy within an image. The region with fewer features indicates the most trivial visible aspects of an image, so alteration within these areas will be less noticeable to any viewer. Furthermore the algorithm will be tested by means of imperceptibility and robustness. Thus a new spatial domain image watermarking scheme will be projected with higher bit capacity.
