Toward Achieving a Trade-Off for SVD-Based Image Watermarking Using Mojette Transform

IEEE Access
Imperceptibility and robustness are a part of trade-off components in image watermarking schemes and become one of the most studied in this field. Increasing imperceptibility usually will reduce the robustness, conversely, increasing the robustness may ...

Text-image watermarking based on integer wavelet transform (IWT) and discrete cosine transform (DCT)

Applied Computing and Informatics, 2019
Text-images still have a great importance, despite the spread of electronic texts. Text-images are protected using digital watermarking. This paper proposes a watermarking method applied to text-images.

GA Based Robust Blind Digital Watermarking [PDF]

, 2018
A genetic algorithm based robust blind digital watermarking scheme is presented. The experimental results show that our scheme keeps invisibility, security and robustness more likely than other proposals in the literature, thanks to the GA pretreatment.

Lost in Space? “Invisible” Marks, Artworks, and Artists

RevistArquis, 2013
This paper addresses the issue of invisibility as relating to visual art through a discussion of my practical and theoretical research. Visual art addresses, at least partly, our sense of visual perception.

Feature Image Watermarking Based on Bicubic Interpolation of Wavelet Coefficients Using CRT

CommIT Journal, 2017
The main objective of watermarking method is to improve the robustness and imperceptibility. This paper introduces an improved CRT watermarking method using absolute value of interpolated wavelet coefficients aiming to improve the imperceptibility and ...

Hughlings Jackson's "imperception" and anosognosia [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2002
One of the earliest to attempts to localise specific functions to anatomical regions of the brain was that of Franz Joseph Gall,1 who distinguished six varieties of memory, which he localised in the frontal lobes. Auburtin in 1864 related the faculty of language to the frontal lobes, and Broca2 and Dax highlighted the left side of the brain.3 The right
