摘    要:由于有功能强大的计算机和图像处理软件的存在,普通用户可以将数字图像篡改成他们想得到的任何形式.如果这些篡改图用在媒体或法律上,对社会将造成很大的影响,所以检测数字篡改变成了一个非常严峻的问题.在大多数情况下,数字篡改图像是很逼真的,但是在处理过程中也会留下一些痕迹.将图像的颜色滤波阵列特性和模糊估计的方法结合起来对图像进行篡改检测,对多幅图像操作,实验证明有不错的检测效果.

关 键 词:篡改图像  模糊估计  颜色滤波阵列  检测篡改  利用  颜色滤波阵列  特性  模糊估计  检测效果  estimation  character  array  color  filter  验证  操作  多幅图像  篡改检测  结合  方法  处理过程  情况  问题  数字图像  影响

Abstract:With powerful computer and editing software,ordinary users could turn digital images into what they want.These forgeries, if used in the mass media or courts of law,can have an important impact on this society.So the detecting of digital tampering has become a crucial problem.In most of the time,digital tampering is not perceptible by human,but some traces of digital tampering may be left in the media during the process.The blur estimation and color filter array character are used to detect forgery.The performance of the proposed method is demonstrated on several forged images and is proved to have good effect.
Keywords:image forgery  blur estimation  color filter array (CFA)  detect forgery
