Multiple codebook data hiding
Type III data embedding
This thesis studies a direct application of multiple codebook data hiding technique in the multimedia applications. It studies the practical implementation of a joint embedding and compression scheme. It presents a study of Type III data embedding technique using multiple codebook design on JPEG-85 compression scheme. The application of the above technique is compared with the Type III data embedding techniques using single codebook design. The comparison is carried out in tenns of the parameters such as mean square error and normalized correlation between the embedded and extracted watermark.
The performance of data hiding rate against the embedding distortion is also studied and on the basis of which, an effort is made to reach an optimal tradeoff between the hiding rate and embedding distortion. On the basis of normalized correlation between the embedded watermark and extracted watermark, an effort is made to ascertain the use of multiple codebook data hiding using type-III methodology and show its advantages over single codebook data hiding.
