摘要：

In recent years, there are many reversible data hiding schemes proposed. Most schemes are guaranteed that the original cover image can be reconstructed completely. When the secret data are hidden in the compression image, the receiver need to extract the secret data, reconstruct the original cover image and compress the image to save the space. In 2006, Chang et al. proposed a reversible data hiding scheme based on side match vector quantisation (SMVQ). Their method can extract the secret data and reconstruct the SMVQ-compressed cover image. In this paper, we proposed a capacity-enhanced reversible data hiding scheme. The hiding payload size of secret data of our proposed scheme is more than those of both Chang and Wu's and Chang et al.'s schemes for VQ- and SMVQ-based compressed images.
