opy-move盲检测中SIFT与SURF算法比较
Comparison of SIFT and SURF Algorithms on Copy-move Forgeries Detection
数字图像的篡改方式有很多种,其中copy-move（复制粘贴）是通过将同幅图像中的一块区域复制粘贴到其他区域实现对图像的篡改,该篡改容易操作且效果明显。SIFT、SURF特征算法是检测图像篡改比较广泛，具有较好的棒性和区分性的算法。本文就从这两种算法对于图像复制粘贴篡改以及后续修饰（模糊、缩放、旋转）的检测速度和匹配点方面进行比较与分析。实验表明SURF是SIFT算法检测速度的3到7倍，并且在图像经过模糊篡改后检测效果好于SIFT算法，但在图像复制粘贴后经过缩放和旋转篡改的精度是不及SIFT算法的。?
here are many ways to tamper with digital images , in which copy-move can achieve tamper images by copying an area and pasting into other areas in the same image, this tamper method is easy to operate and the effect is obvious. SIFT and SURF algorithms are widely used with good robustness and discrimination.In this paper, we compare these two kinds of algorithms about the detection speed and matching points if the image have been tampered with copy-move and subsequent modifications (blur, rotate, scale).The experiment results show that SIFT algorithm is 3 to 7 times faster than the detection rate of SURF algorithm,and the detection effect is better than the SIFT algorithm after the image is tampered with blur.But the accuracy is not as good as the SIFT algorithm when the image tampered with scaling and rotation after copy-move.
