Abstract
A content-based watermarking strategy relying on an affine invariant embedding domain obtained from affine invariant interest points and a watermark insertion via quantization index modulation is analyzed, namely the effects on the performance of the whole watermarking scheme carried out by the presence or absence of interpolation operations during the design of the invariant domain.
