一种基于盒子维的图像复制-粘贴篡改检测算法

摘要

提出了一种基于盒子维的图像复制-粘贴检测算法。对图像分块后,提取各分块的盒子维与几何矩相结合做为各块的特征量,而后通过对图像块特征向量进行相似性检测来定位篡改区域。实验表明：该算法有较强检测能力,能抵抗高斯白噪声等后处理操作。%In this paper,we put forward a new algorithm for detecting image copy-move forgery based on fractal box dimension is proposed in this paper.The image is firstly divided into overlapping blocks,the fractal box dimension and the geometric moment of each blocks is extracted as the eigenvetors.Then the forgery parts are located by the detection of the similarity between these blocks.The experiments show that the validity of the algorithm on various types of post processing such as Gaussian white noise and so on.
