Hiding digital image watermarking in a sound signal using Wavelet Transform and Singular Value Decomposition [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2013
The outgrowing of multimedia applications in communications network brought about an increasing need to provide qualified methods to protect these media and secure communication. These methods include encryption and information hiding.

Error bound of the multilevel adaptive cross approximation (MLACA) [PDF]

open access: yes, 2016
An error bound of the multilevel adaptive cross approximation (MLACA 1, which is a multilevel version of the adaptive cross approximation-singular value decomposition (ACA-SVD), is rigorously derived.

Secure and Robust Image Watermarking Scheme Using Homomorphic Transform, SVD and Arnold Transform in RDWT Domain

open access: yesAdvances in Electrical and Electronic Engineering, 2019
The main objective for a watermarking technique is to attain imperceptibility, robustness and security against various malicious attacks applied by illicit users. To fulfil these basic requirements for a scheme is a big issue of concern.

SVD-matching using SIFT features

open access: yesGraphical Models, 2006
The paper tackles the problem of feature points matching between pair of images of the same scene. This is a key problem in computer vision. The method we discuss here is a version of the SVD-matching proposed by Scott and Longuet-Higgins and later modified by Pilu, that we elaborate in order to cope with large scale variations.

Principal component analysis and its generalizations for any type of sequence (PCA-Seq)

open access: yesВавиловский журнал генетики и селекции, 2020
In the 1940s, Karhunen and Loève proposed a method for processing a one-dimensional numeric time series by converting it into multidimensional by shifts. In fact, a one-dimensional number series was decomposed into several orthogonal time series.

A Randomized Tensor Train Singular Value Decomposition

open access: yes, 2017
The hierarchical SVD provides a quasi-best low rank approximation of high dimensional data in the hierarchical Tucker framework. Similar to the SVD for matrices, it provides a fundamental but expensive tool for tensor computations. In the present work we

Blockwise SVD with error in the operator and application to blind deconvolution [PDF]

open access: yes, 2012
We consider linear inverse problems in a nonparametric statistical framework. Both the signal and the operator are unknown and subject to error measurements.
