Digital image watermarking technique based onvector quantisation
Zhe‐Ming Lu, Songlin Sun · Electronics Letters · 2000
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, and the watermarked image is robust to VQ compression with the same codebook. The simulation results prove the effectiveness of this technique.
