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…
Embedding of binary image in the Gray planes
V. N. Gorbachev, L. A. Denisov, E. M. Kainarova
For watermarking of the digital grayscale image its Gray planes have been used. With the help of the introduced representation over Gray planes the LSB embedding method and detecti…
Decay and storage of multiparticle entangled states of atoms in collective thermostat
A. M. Basharov, V. N. Gorbachev, A. A. Rodichkina
We derive a master equation describing the collective decay of two-level atoms inside a single mode cavity in the dispersive limit. By considering atomic decay in the collective th…
Quantum channel for light based on integrals of motion
V. N. Gorbachev, A. I. Trubilko
A method based on integrals of motion for collective processes has been introduced to achieve physical schemes in which one of the systems is insensitive to interaction. Decoherenc…
