摘要 为了与图像压缩标准JPEG2000相适应,提出了两种可直接在JPEG2000压缩域内进行信息隐藏的方法,分别采用JPEC2000编码过程和解码过程进行实现。它们既支持无损压缩,也适用于有损压缩,从而具有较广的适用范围。实验结果表明这两种实现方法具有较好的不可见性和压缩性。 To comply with JPEG2000, in this paper we propose two methods about how to hide information in digital images compressed with JPEG2000. They are respectively implemented using JPEG2000 encoding process and decoding process. By supporting both loseless compression and lossy compression, the two schemes can be used in more applications. Testing results also indicate that they have good characteristics such as transparency and compression.
