近年来，许多研究人员对可逆数据隐藏技术进行了研究，大多数人提出了只保证原始封面图像能够完全重建的可逆数据隐藏方案。一旦秘密数据被嵌入到压缩域中，并且接收方希望以压缩模式存储封面图像以节省存储空间，则接收方必须提取秘密数据，重建封面图像，并再次压缩封面图像以生成压缩代码。提出了一种基于边匹配矢量量化(SMVQ)的数字压缩图像可逆数据隐藏方案。在该方案中，接收端只需执行两个步骤即可达到相同的目的：提取秘密数据和重构原始SMVQ压缩码。实验结果表明，对于基于VQ和基于SMVQ的压缩图像，本文提出的方案在隐藏数据量、视觉质量和压缩比等方面均优于其他信息隐藏方案。实验结果进一步证实了该方案的有效性和可逆性。
Many researchers have studied reversible data hiding techniques in recent years and most have proposed reversible data hiding schemes that guarantee only that the original cover image can be reconstructed completely. Once the secret data are embedded in the compression domain and the receiver wants to store the cover image in a compression mode to save storage space, the receiver must extract the secret data, reconstruct the cover image, and compress the cover image again to generate compression codes. In this paper, we present a reversible data hiding scheme based on side match vector quantization (SMVQ) for digitally compressed images. With this scheme, the receiver only performs two steps to achieve the same goal: extract the secret data and reconstruct the original SMVQ compression codes. In terms of the size of the secret data, the visual quality, and the compression rate, experimental results show that the performance of our proposed scheme is better than those of other information hiding schemes for VQ-based and SMVQ-based compressed images. The experimental results further confirm the effectiveness and reversibility of the proposed scheme.
