Journal ArticleDOI
Multipurpose image watermarking algorithm based on multistage vector quantization
TL;DR: This paper presents a novel multipurpose digital image watermarking method based on the multistage vector quantizer structure, which can be applied to image authentication and copyright protection.
Journal ArticleDOI
Digital image watermarking technique based on vector quantisation
Zhe-Ming Lu,Sheng-He Sun +1 more
TL;DR: A digital image watermarking technique based on vector quantisation (VQ) is presented that uses codeword indices to carry the watermark information and simulation results prove the effectiveness of this technique.
Journal ArticleDOI
An efficient encoding algorithm for vector quantization based on subvector technique
TL;DR: A new and fast encoding algorithm for vector quantization is presented that makes full use of two characteristics of a vector: the sum and the variance.
Journal ArticleDOI
VQ-based digital image watermarking method
TL;DR: A vector-quantisation (VQ)-based watermarking method is presented which utilises the codebook expansion technique and is efficient, provides enhanced security and the watermarked image is robust against the effects of VQ compression.
Journal ArticleDOI
Vector quantization based on genetic simulated annealing
TL;DR: Experimental results show that GVQ and GSAVQ need a little longer CPU time than, the maximum decent (MD) algorithm, but they outperform MD by 0.2–0.5 dB in PSNR.
