Novel content-adaptive tampering detection and self-recovery algorithm study
摘要
Abstract
In order to address the problem that embedding a large number of watermarks(authentication watermark and ref-erence watermark)in the original image can easily cause image distortion,we propose to embed a small amount of reference watermark.To reduce the image distortion,it is proposed to embed a small amount of reference watermark information in the edges,contours,and other regions of the original image.In recovering the tampered region,it is proposed to transform the tampered block matching problem into a minimization problem of non-local self-similar image blocks using an image restora-tion method,and then replicate the similar information of the attack image itself to recover the tampered region.The experi-mental results show that the algorithm obtains the mean PSNR of the embedded watermarked image over 60 dB and the mean PSNR of the recovered image over 40 dB at a watermark capacity of 0.015 626.关键词
