基于不变矩特征的图像区域复制粘贴篡改检测
Detection of image region copy-move forgery based on moment invariant features
摘要
Abstract
Targeting a common means of tempering-the image region copy-move forgery, this paper proposes a detection algorithm based on moment invariant features. The detected image is divided into multiple same-sized overlapping blocks, whose moment invariant features and histogram features are extracted to compose a feature vector. The feature vector is sorted by dictionary to locate the copy-move region according to the predetermined similarity criteria. Experimental results show that the proposed algorithm performs better than the classical detection algorithm based on PC A (Principal Component Analysis) in terms of robustness against rotate operation and it can detect the 90° and 180° rotation accurately.关键词
