代码描述

中文说明:本文所作的贡献是信息的一种新技术能够在数字图像中消除检出微量的关于处理。本文提出了一种可靠的方法,用于删除或隐藏的处理和操作。据此可以估算压缩前的变换系数的分布,然后为压缩的图像添加一些特制的噪音,这样修改后的图像的系数与分布情况相符估计在压缩之前去除图像处理的痕迹。执行此框架工作被首创,查出及消除痕迹从图像系数,它基于图像变换系数的分析。所提出的重要特征是方法的隐藏的图像和它的操纵其能力可以扩展以删除图像增强期间创建的签名痕迹。.结果表明它是一个可靠的人。


English Description:

The contribution of this paper is a new technology of information processing, which can eliminate the problem of trace detection in digital image. This paper presents a reliable method for deleting or hiding operations. According to this, we can estimate the distribution of the transform coefficients before compression, and then add some special noise to the compressed image, so that the coefficients of the modified image are consistent with the distribution. It is estimated that the traces of image processing can be removed before compression. Performing this framework work was pioneered to detect and eliminate traces from image coefficients, which are based on the analysis of image transformation coefficients. An important feature of the proposed method is the hidden image and its manipulation, whose ability can be extended to delete signature traces created during image enhancement. It turns out that he is a reliable person.
