Abstract: | A digital image watermarking technique based on vector quantisation (VQ) is presented. This technique uses codeword indices to carry the watermark information. The technique is secret and efficient: the watermarked image is robust to VQ compression with the same codebook. The simulation results prove the effectiveness of this technique |
