An image digital watermarking based on DWT in invariant wavelet domain

Abstract

In the face of geometrical attacks,all shortcomings of the almost all digital watermarking algorithms have been exposed.Perhaps there is no algorithm against every attack especially geometrical attacks.It is designed a novel blind image watermarking algorithm of Scalar Costa System based on the DWT transformation in the Rotation-and Scale-and Translation-(RST) Moment Invariant Wavelet,i.e.RSTMIW domain.The experiments show that this novel algorithm is robust against RST geometrical,filter and noise attacks,however,sensitive to some local geometrical attacks.
