Abstract: By using Wasserstein’s concept of the barycentric and barycentric coordinates,a blind region detection algorithm for image region-duplication forgery using Wasserstein barycentric coordinates as image descriptors is proposed.The initial search block of the image is determined by measuring the minimum Euclidean distance between the Wasserstein barycentric coordinates of each image block.The initial search block is extended,and a patch with high correlation is searched for by using the improved PatchMatch algorithm to search for a complete image repetition area.Experimental results show that the proposed algorithm can detect the repeated region by using blind detection algorithm based on the Wasserstein histogram Euclidean metric.The copying and pasting forged regions are also very robust for forged regions with rotation and zoom geometry attacks.
