  • 摘要:

    該文使用極坐標正弦變換(PST)特征對圖像進行Copy-move篡改檢測，將待檢測圖像轉(zhuǎn)換成灰度圖并進行PST特征提取，并采用改進的快速近似最近鄰搜索算法PatchMatch對特征描述符進行匹配，以克服匹配全局描述符帶來的處理時間較長的缺點。實驗分析表明，該文所提方法不僅對圖像的線性Copy-move篡改和旋轉(zhuǎn)干擾篡改有很好的效果，而且對噪聲和JPEG壓縮干擾篡改也具有一定的魯棒性。最后對綜合干擾篡改實驗測試發(fā)現(xiàn)，在綜合篡改幅度較小的情況下，準確率可以達到98.0%。

    Abstract:

    Polar Sine Transform (PST) is used to detect Copy-move forgeries in the paper, and the image to be detected is transformed into gray scale image and feature extraction is carried out by PST. Improved PatchMatch, a fast approximate nearest neighbor search algorithm, is used to match feature descriptors to overcome the problem of long time consuming caused by matching global descriptors. Experiments show that the proposed method is not only effective for linear Copy-move forgeries and rotation interference forgeries, but also robust to noise and JPEG compression interference forgeries. Finally, the experimental results of synthetic interference forgeries show that the accuracy can reach 98.0% when the synthetic forgeries range is small.
