The Hessian biased singular value decomposition method for optimization and analysis of force fields [PDF]

open access: yes, 1996
We present methodology (HBFF/SVD) for optimizing the form and parameters of force fields (FF) for molecular dynamics simulations through utilizing information about properties such as the geometry, Hessian, polarizability, stress (crystals), and elastic ...

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.

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.

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.

Reseaech on identification of caving coal and rock traits

open access: yesGong-kuang zidonghua, 2017
In order to recognize caving coal and rock traits in fully mechanized caving face, an identification method based on continuous wavelet transform and improved singular value decomposition (SVD) was proposed.

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.
