Protect digital images based on matrix norm quantization of digital, watermarking algorithm
2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery, 2009As a protection and authentication technology, digital watermarking technology has been used in the image field. In this paper, a digital watermarking algorithm is proposed based on integer wavelet transform to protect digital images and estimate its integrity and authenticity. Using matrix norm quantization, watermarks are embedded into low-frequency,

Using Matrix Decomposition and Frequency Transforms to Detect Forgeries in Digital Images
2019 IEEE-RIVF International Conference on Computing and Communication Technologies (RIVF), 2019Digital images are very popular, but they are quite easy to manipulate. This may have bad consequences, especially when the editing changes important content in the images. Therefore, detecting traces of modifications in digital images is an urgent need.

A novel and efficient digital image steganography technique using least significant bit substitution
Scientific ReportsSteganography is used to hide sensitive types of data including images, audio, text, and videos in an invisible way so that no one can detect it. Image-based steganography is a technique that uses images as a cover media for hiding and transmitting ...

Bimrocks are a kind of rocks in which blocks are randomly distributed in a matrix. Despite their wide distribution in nature, their significant effects on the failure of rock structures such as slopes, mines and tunnels have been neglected.

A Novel Digital Image Hiding Scheme Based on Matrix Decomposition
2009 International Forum on Information Technology and Applications, 2009Digital image is an important way to get information, so people pay more attention to the security of digital images. The technology of digital image hiding was born in order to enhance the security of digital images. The stego-images obtained by some hiding methods will not get people's attention, which will protect digital images from being modified ...

Digital-Image-Based Study of Circular Holes in an Elastic Matrix
MRS Proceedings, 1990AbstractUsing a digital-image-based representation of a continuum composite, we apply computer simulation techniques to obtain the elastic moduli of a matrix containing randomly-centered circular voids. As the area fraction of the voids increases, the elastic moduli of the composite decrease until they eventually vanish at the percolation threshold. We

Digital image forensic approach based on the second-order statistical analysis of CFA artifacts
Digital Investigation. The International Journal of Digital Forensics and Incident Response, 2020The truthfulness of digital images can be evaluated by investigating the CFA artifacts introduced due to the interpolation process of the image acquisition phase.
