基于彩色SIFT的图像复制粘贴篡改检测
首发时间:2020-03-20
摘要:21世纪随着计算机图像处理技术的高速发展,各种手机端、PC端的图像编辑软件诸如PS、美图秀秀应运而生,这些软件操作简单,人们可以轻松地运用这些软件去修改和编辑真实的图片,各种图像篡改事件层出不穷。本文就针对篡改检测中普通特征点误匹配率较高的问题,提出一种基于opponentSIFT算子的复制粘贴篡改检测算法,在无需任何先验知识的情况下能够对篡改图像进行有效的鉴别并进行篡改区域的定位,实验表明该方法可以有效地降低误匹配率,并对噪声、JPEG重压缩、图像模糊具有较强的鲁棒性。

Image copy-move tamper detection based on color SIFT
Abstract:With the rapid development of computer image processing technology in the 21st century, a variety of mobile phone and PC-side image editing software such as PS and Meitu Xiuxiu arise at the historic moment. These software operations are simple and people can easily use these software to modify and edit the real pictures.therefore,various image tampering events emerge endlessly. Aiming at the problem of high mismatch rates of common feature points in tamper detection., this paper proposes a copy-move tamper detection algorithm based on the opponentSIFT operator. It can effectively identify tampered images and locate tampered areas without any prior knowledge..Experiments show that this method can effectively reduce the mismatch rate and is robust to noise, JPEG recompression, and image blur.
