Comparison of two wavelet based image watermarking schemes

This paper presents two semi-blind watermarking techniques, based on sets of significant wavelet coefficients, in the three lowest detail subbands of a cover-image. The first method modifies the magnitude of triplets of significant coefficients, according to a sequence of information bits. We show t...
