Abstract: Content authentication requires that the image watermarks must highlight malicious attacks while tolerating

#Content authentication # self authentication # recovery watermark # DWT # PQ sequence

Abstract: This paper presents a new approach for evaluating image quality. The method is based on the histogram similarity

#Image quality measures # RMS contrast # histogram similarity # SSIM # HIQ # minkowski distance metric

Abstract: In this paper, authors propose a new reversible data hiding scheme that has two passes. In first pass, the cover

#Reversible data hiding # pixel location # location map # non-overlapping blocks
