摘要 在数字图像伪造检测中,取证过程容易导致伪造痕迹丢失,造成图像内容鉴别困难。为此,研究数字图像伪造检测方法的可靠性。给出图像复制-移动伪造检测流程,分析下采样处理对图像伪造检测的影响。理论分析与实验结果表明,在一定情况下,下采样处理会移除数字图像的伪造痕迹,影响检测结果。 In view of image content authentication problem caused by some forensic operations disturbing forgery traces, this paper investigates the reliability of digital image forgery detection methods. It addresses the use of down-sampling process in image forgery detection, and in-depthly analyzes the influence of sub-sampling process on image copy-move forgery detection. Theoretical analysis and experimental results demonstrate that sub-sampling operation may remove the telltale traces of image copy-move forgery and influence the detection results.
