Influence Analysis of Down-sampling on Digital Images Forgery Detection
摘要
Abstract
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-depthiy 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.关键词
