—This paper proposes a CS based watermarking
algorithm. In this algorithm, the watermarking image embeds
into the compressive measurement vectors by the encoder. The
measurement vectors are sparse in suitable basis. The resulting
watermarked measurements recover by using both the OMP
and the OMP-PKS reconstruction algorithms. Then the
decoder uses to extract the watermarking image.
In an experimental study, results obtained by the OMP and
the OMP-PKS algorithms are compared. The results show that
the OMP-PKS algorithm achieves performance superior to that
of the OMP reconstruction algorithm.
