Digital watermarking algorithm based on wavelet moment modulating
|
Abstract:
To enhance the capacity to resist attacks such as rotation and cropping,an algorithm based on wavelet moment modulation was proposed.Wavelet moments are invariant to rotation,translation and scaling change of the host image,and they also have wavelet's ability:to observe signal with multi-resolution.An imperceptible watermarking was hidden in a host image by modulating the wavelet moments of the host image.The experimental results in section 3 and section 4 show that this algorithm can effectively resist signal processing attacks,such as filtering,compression,especially rotation and cropping,and the detection does not need the host image.
