- W2352265591 abstract "The copy and paste operation of image region,one of the most commonly used tamper means,can hide important goal or cause some false appearance. According to the tamper modelcopy-transform-mobile-paste,a blind detection algorithm for fake images is proposed. Firstly,the image's features are extracted by using SIFT algorithm; Secondly,the extracted vectors of image features are matched with the nearest neighbor search of the product quantization to locate roughly the tampered region; Finally,the tampered region is located accurately by calculating the Euclidean distance of suspicious blocks. The experimental results show that the algorithm can not only detect the copy and paste tamper region with rotation and zoom transformations,but also can resist blur and noise post-processing." @default.
