On basis images for the digital image representation
V. N. Gorbachev, L. A. Denisov, E. M. Kaynarova +2
Digital array orthogonal transformations that can be presented as a decomposition over basis items or basis images are considered. The orthogonal transform provides digital data sc…
On the steganographic image based approach to PDF files protection
V. N. Gorbachev, L. A. Denisov, E. M. Kaynarova +1
Digital images can be copied without authorization and have to be protected. Two schemes for watermarking images in PDF document were considered. Both schemes include a converter t…
The blind detection for palette image watermarking without changing the color
V. N. Gorbachev, E. M. Kaynarova, I. K. Metelev +1
To hide a binary pattern in the palette image a steganographic scheme with blind detection is considered. The embedding algorithm uses the Lehmer code by palette color permutations…
Color to Gray and Back transformation for distributing color digital images
V. N. Gorbachev, E. M. Kaynarova, I. K. Metelev +1
The Color to Gray and Back transformation watermarking with a secrete key is considered. Color is embedded into the bit planes of the luminosity component of the YUV color space wi…
