Block-based discrete wavelet transform singular value decomposition image watermarking scheme using human visual system characteristics

Block-based discrete wavelet transform-singular value decomposition image watermarking scheme using human visual system characteristics  Abstract Digital watermarking has been suggested as a way to achieve digital protection. The aim of digital watermarking is to insert the secret data into the image without significantly affecting the visual quality. This study presents a robust block-based image watermarking […]


Illuminant -based Transformed Spaces for Image Forensics

Illuminant -based Transformed Spaces for Image Forensics Abstract In this paper, we explore transformed spaces, represented by image illuminant maps, to propose a methodology for selecting complementary forms of characterizing visual properties for an effective and automated detection of image forgeries. We combine statistical telltales provided by different imagedescriptors that explore color, shape, and texture features. We focus on detecting image forgeries containing people and […]
