We decided to use the iris image and lossy compress it using JPEG to make its size fit within the available lossless capacity.
      


In this paper,we present a novel HVS based visual masking and self adaptive image public watermarking using chaotic array,and define a new noisesensitivity using forth order cumulant in visual masking.In this algorithm,chaotic array is embedded to the sub low frequency coefficients of the block DCT,then visual masking is made according to the noisesensitivity.Under the affect of noisesensitivity,Visual masking accomplish self adaptive controllable intensity of watermark.Without original image,we can remarkably...

In this paper,we present a novel HVS based visual masking and self adaptive image public watermarking using chaotic array,and define a new noisesensitivity using forth order cumulant in visual masking.In this algorithm,chaotic array is embedded to the sub low frequency coefficients of the block DCT,then visual masking is made according to the noisesensitivity.Under the affect of noisesensitivity,Visual masking accomplish self adaptive controllable intensity of watermark.Without original image,we can remarkably detect the existence of watermark by public key.With common signal distortion or geometric distortion (such as lossy compress,cropping etc.),watermark can achieve better robust.

本文提出了一种新的使用混沌阵列 ,基于HVS视觉掩盖自适应的公开图像水印算法 ,利用四阶累积量定义了视觉掩盖中的噪声敏感度 .该方法将混沌阵列作为水印嵌入到图像子块的DCT次低频系数中去 ,然后根据噪声敏感度进行视觉掩盖 .实验结果表明 ,在噪声敏感度的作用下 ,视觉掩盖实现了自适应地调整水印嵌入强度 ;在无原始数据的情况下 ,通过使用密钥能够清晰地检测出水印的存在 ;在常见的信号失真和几何失真下 (有损压缩 ,剪切等 ) ,水印具有很好的稳健性 .

It is the first time to expound the watermark application under images uniting in this paper. With the affecting of JPEG lossy compressing, the universal solving scheme is proposed, and the corresponding security analysis is made. In the direction of this scheme, a watermark algorithm is proposed which can resist the JPEG lossy compressing and images uniting question. The test results prove its both characters.

该文首次阐述水印在图像合并操作下的应用,综合考虑JPEG有损压缩的影响,提出了通用的解决方案, 并作了相应的安全性分析。在该方案的指导下,提出了一种抗JPEG压缩和图像合并的水印算法,通过试验,证明该算法具有很强的抗压缩性和抗合并性。

Moving images have great data relativity along time zone,which are used to shield unchanged data in order to get large same continuum data.Those data can be compressed on run-length encoding.Two algorithms acted between frames are put forward,that are loss-free compress algorithm based on XOR and lossy compress algorithm based on differential quantum,which are benefit for distance education,network meeting and watching system.

运动图像在时间域上的数据相关性很大,利用相关性屏蔽无变化数据,使之表现为大量连续相同数据,进而用行程编码进行压缩。对帧间施行的基于异或运算的无损压缩算法和基于差值量化的有损压缩算法对远程教学及网络视频会议图像传输、监视系统的开发有重要实用价值。
