ABSTRACT Data hiding in the compression domain is a very common method. Nowadays, the images to be transferred are usually compressed first. Therefore, data hiding in the compression domain becomes more and more important. Joint-neighbor coding uses the pixel that wants to be compressed, and its nearby pixels are used to embed the secret information. Absolute Moment Block Truncation Coding (AMBTC) and the joint-neighbor coding are combined to embed the secret information in the compression domain. Compared with Block Truncation Coding (BTC), AMBTC has lower computation and less distortion. The experiment result shows that our proposed method is effective.

一种改进的可逆数据隐藏块截断编码压缩图像

摘要 在压缩域中隐藏数据是一种非常常见的方法。现在，要传输的图像通常首先被压缩。因此，压缩域中的数据隐藏变得越来越重要。联合邻居编码使用想要压缩的像素，其附近的像素用于嵌入秘密信息。绝对矩块截断编码 (AMBTC) 和联合邻居编码相结合，将秘密信息嵌入到压缩域中。与块截断编码 (BTC) 相比，AMBTC 具有更低的计算量和更少的失真。实验结果表明我们提出的方法是有效的。
