Image Quality Assessment Based on Quaternion Singular Value Decomposition

open access: yesIEEE Access, 2020
We propose an image quality assessment metric based on quaternion singular value decomposition that represents a color image as a quaternion matrix, separates image noise information using singular value decomposition and extracts features from both the ...

A blind watermarkingalgorithm based on DWT and SVD

open access: yesJournal of Measurement Science and Instrumentation, 2014
This paper presents a new digital image blind watermarking algorithm based on combination of discrete wavelet transform(DWT)and singular value decomposition(SVD).First of all,we make wavelet decomposition for the original image and divide the acquired ...

Weak peak identification of gamma spectrum based on singular value decomposition

open access: yesHe jishu
BackgroundWhen performing gamma-ray spectroscopy analysis of samples with low levels of radioactive nuclide content, the weak peaks are difficult to be identified.PurposeThis study aims to propose a new method for identifying peaks in γ spectra by ...

Modeling Electromechanical Overcurrent Relays Using Singular Value Decomposition

open access: yesJournal of Applied Mathematics, 2012
This paper presents a practical and effective novel approach to curve fit electromechanical (EM) overcurrent (OC) relay characteristics. Based on singular value decomposition (SVD), the curves are fitted with equation in state space under modal ...

SINGULAR VALUE DECOMPOSITION IN DIGITAL IMAGE ANALYSIS

open access: yesInformatika, 2017
The paper describes new properties of the singular matrix decomposition. It is shown that permutation of rows or columns of the matrix or matrix rotation by 90 degrees does not change the set of its singular numbers.

Through-Wall Image Enhancement Based on Singular Value Decomposition

open access: yesInternational Journal of Antennas and Propagation, 2012
Singular value decomposition and information theoretic criterion-based image enhancement is proposed for through-wall imaging. The scheme is capable of discriminating target, clutter, and noise subspaces.

The Stability of Isometry by Singular Value Decomposition

open access: yesMathematics
Hyers and Ulam considered the problem of whether there is a true isometry that approximates the ε-isometry defined on a Hilbert space with a stability constant 10ε.

Fractional Norm Regularization Using Truncated Singular Value Decomposition

open access: yesIEEE Access
In a previous work, a solution to the fractional norm regularization (FNR) was discovered in a closed form and an inverse perturbation was adopted as a tool to overcome the ill condition of a matrix whose inverse is required by the fixed-point FNR.
