Abstract
Based on digital watermarking technique of vector quantization,in vector coding process,in the protected im-age in a typical digital watermark is embedded,the watermark can be recovered from the image,which can effectively in a copyright dispute for copyright proof.Whisper of vector quantization in the according to the different characteristics are de-fined into different groups,then each binary watermark bits are embedded into the selected vector quantization coding block, which is characterized in that the watermark also exist in the vector quantization compression image and vector quantization decoding of reconstruction image.Because the watermark is hidden in the compressed image,the compression image with the watermark has the characteristics of small size,fast transmission speed and the storage space can be saved in the compres-sion,thus replacing the original transmission on the internet.In addition,the reconstructed image is robust to prevent dam-age or remove the watermark.关键词
