RHFM结合形态学滤波的数字图像Copy-Move篡改取证方法
Forensics method of digital image copy-move forgery based on RHFM and morphological filtering
摘要
Abstract
For the image is easy to attack by copy⁃move forgery,a forensics method of image copy⁃move forgery based on radial⁃harmonic Fourier moment and morphological filtering is proposed. The detection image is divided into multiple overlapping circular area blocks,after that the invariant feature of the circular area blocks is extracted by means of radial⁃harmonic Fourier moment,and sorted in the form of dictionary. And then,the Euclidean distances among the feature vectors are calculated and compared to match the area blocks and obtain the detection graph. Finally,the window filtering and morphologic operation are used to remove the false matching results in detection graph to get the final detection graph. The experimental results show that the proposed method can effectively detect the copy⁃move forgery attack,and has good robustness for the attacts of forgery image affine transform and signal processing.关键词
