Is there a relationship between peak‐signal‐to‐noise ratio and structural similarity index measure?

open access: yesIET Image Processing, 2013
In this study, the authors analyse two well‐known image quality metrics, peak‐signal‐to‐noise ratio (PSNR) as well as structural similarity index measure (SSIM), and the authors derive an analytical relationship between them which works for some kinds of common image degradations such as Gaussian blur, additive Gaussian noise, Jpeg and Jpeg2000 ...

Peak Detection as Multiple Testing [PDF]

open access: yes, 2010
This paper considers the problem of detecting equal-shaped non-overlapping unimodal peaks in the presence of Gaussian ergodic stationary noise, where the number, location and heights of the peaks are unknown.

Performance analysis of peak signal-to-noise ratio and multipath source routing using different denoising method

open access: yesBulletin of Electrical Engineering and Informatics, 2022
The problem of denoising iris pictures for iris identification systems will be discussed, as well as a novel solution based on wavelet and median filters. Different salt and pepper extraction algorithms, as well as Gaussian and speckle noises, were used.

Infrared–Visible Image Fusion via Cross-Modal Guided Dual-Branch Networks

open access: yesApplied Sciences
In the field of low-altitude aerial drone data fusion, the fusion of infrared and visible light images remains challenging due to issues such as large modal differences, insufficient cross-modal alignment, and limited global context modeling. Traditional

Comparative Analysis of Filters for Cancellation of Power-line-interference of ECG Signal [PDF]

open access: yesInternational Journal Bioautomation, 2019
Filtering noises/artifacts from the electrocardiogram (ECG) can sustain the efficient clinical decision making. Comparative analysis of several filtering techniques is proposed: two adaptive noise cancellation techniques, Least Mean Square (LMS ...

Novel Implementation of Audio Encryption Using Pseudorandom Byte Generator

open access: yesApplied Sciences, 2021
In this paper, we present an algorithm for encrypting audio files based on the Ikeda map, a mathematical function of chaos theory. Detailed experimental, security and theoretical analysis is provided on the proposed algorithm using histogram analysis ...

Fuzzy Logic and Singular Value Decomposition based Through Wall Image Enhancement [PDF]

open access: yes, 2012
Singular value decomposition based through wall image enhancement is proposed which is capable of discriminating target, noise and clutter signals. The overlapping boundaries of clutter, noise and target signals are separated using fuzzy logic.

Performance of peak signal‐to‐noise ratio quality assessment in video streaming with packet losses

open access: yesElectronics Letters, 2016
The effect of packet losses over error‐prone networks on visual quality of distributed video contents, estimated through subjective opinion and PSNR as an objective measure is analysed. It is shown that, within a fixed content, the variation of PSNR is a reliable indicator of the variation of packet loss rates.

Extracting More Data from LiDAR in Forested Areas by Analyzing Waveform Shape [PDF]

open access: yes, 2012
Light Detection And Ranging (LiDAR) in forested areas is used for constructing Digital Terrain Models (DTMs), estimating biomass carbon and timber volume and estimating foliage distribution as an indicator of tree growth and health. All of these purposes
