The purpose of this paper is to embed information on codes when using search-order coding (SOC) to compress index table. The proposed method reassigned the shorter indicators to the indices that can be transformed to SOC codes and those that can not be transformed are assigned by the other indicators. If the cover image is a smooth image, the proposed method can significantly reduce the size of compression...
This paper proposes a novel data embedding method for embedding secrets into VQ indices by using the Chinese Remainder Theorem (CRT). In the experimental results, the hiding capacity is flexible which corresponds to the pre-defined prime parameters. In addition, a reversible mechanism is imported into the scheme so the original VQ indices can be restored after extracting secrets retrieval.
