The Influence of Steganographic Methods and QR Code Resolutions on Data Hiding in Cover Images
Acta Electrotechnica et Informatica, 2023 This work deals with digital image processing using the steganography technique in real life. Various steganography techniques face data authentication, data security, and copyright issues.

Radio Observations of the AGN and Gas in Low Surface Brightness Galaxies [PDF]
, 2006 LSB galaxies have low metallicities, diffuse stellar disks, and massive HI disks. We have detected molecular gas in two giant LSB galaxies, UGC 6614 and F568-6. A millimeter continuum source has been detected in UGC 6614 as well.

A novel steganography approach for audio files [PDF]
, 2020 We present a novel robust and secure steganography technique to hide images into audio files aiming at increasing the carrier medium capacity. The audio files are in the standard WAV format, which is based on the LSB algorithm while images are ...

Environment, morphology and stellar populations of bulgeless low surface brightness galaxies
, 2015 Based on the Sloan Digital Sky Survey DR 7, we investigate the environment, morphology and stellar population of bulgeless low surface brightness (LSB) galaxies in a volume-limited sample with redshift ranging from 0.024 to 0.04 and $M_r$ $\leq$ $-18.8$.

Dynamical Stability and Environmental Influences in Low Surface Brightness Disk Galaxies [PDF]
, 1996 Using analytic stability criteria, we demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global nonaxisymmetric modes such as bars.

Using the Genetic Algorithm in Developing a Method for Steganography [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 This paper has developed a method for hiding in images, as it was first encrypt the secret message chaoticlly using the chaotic encryption algorithm and secondly execute the steganography in two phases, the first divide the cover image (.BMP, .PNG) to a ...

Low Surface Brightness Galaxies around the HDF-S: II. Distances and volume densities
, 2007 With this study we aim at the spectroscopic verification of a photometrically selected sample of Low Surface Brightness (LSB) galaxy candidates in a field around the Hubble Deep Field-South (HDF-S).

21-cm H I emission from the Damped Lyman-alpha absorber SBS 1543+593 [PDF]
, 2001 We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped Lyman-alpha (DLA) absorption line in the spectrum of the background QSO HS 1543+5921 (z=0.807). We obtain an accurate measure of the velocity

Image Steganography using LSB and LSB+Huffman Code
International Journal of Computer Applications, 2014 Steganography is an important area of research in recent years involving a various number of applications. It is the science of embedding information into cover of the media such as text, image, audio, and video. This paper uses two techniques for Steganography (text into image): Least Significant Bit (LSB) and Least Significant Bit with Huffman code ...
