Associations of noise kurtosis, genetic variations in NOX3 and lifestyle factors with noise-induced hearing loss

open access: yesEnvironmental Health, 2020
Background Noise-induced hearing loss (NIHL) is a complex disease caused by environmental and genetic risk factors. This study was to explore the association of noise kurtosis, triphosphopyridine nucleotide oxidase 3 (NOX3) and lifestyles with NIHL ...

A novel video noise reduction method based on PDE, adaptive grouping, and thresholding techniques

open access: yesThe Journal of Engineering, 2021
Undoubtedly, video block‐matching and 3D filtering (VBM3D) has achieved a significant improvement in video denoising. Nevertheless, in practice, failure to distinguish between the different noise areas, ignoring noise variances and pixel intensity, false‐

Using Noise Level to Detect Frame Repetition Forgery in Video Frame Rate Up-Conversion

open access: yesFuture Internet, 2018
Frame repetition (FR) is a common temporal-domain tampering operator, which is often used to increase the frame rate of video sequences. Existing methods detect FR forgery by analyzing residual variation or similarity between video frames; however, these

Video recording true single-photon double-slit interference [PDF]

open access: yes, 2016
As normally used, no commercially available camera has a low-enough dark noise to directly produce video recordings of double-slit interference at the photon-by-photon level, because readout noise significantly contaminates or overwhelms the signal.

Video Denoising and Enhancement via Dynamic Video Layering

open access: yes, 2017
Video denoising refers to the problem of removing "noise" from a video sequence. Here the term "noise" is used in a broad sense to refer to any corruption or outlier or interference that is not the quantity of interest.

BCI-Walls: A robust methodology to predict if conscious EEG changes can be detected in the presence of artefacts.

open access: yesPLoS ONE, 2023
Brain computer interfaces (BCI) depend on reliable realtime detection of conscious EEG changes for example to control a video game. However, scalp recordings are contaminated with non-stationary noise, such as facial muscle activity and eye movements ...

Development of a video-rate range finder using dynamic threshold method for characteristic point detection [PDF]

open access: yes, 1999
This study develops a video-rate stereo range finding circuit to obtain the depth of objects in a scene by processing video signals (R, G, B, and brightness signals) from binocular CCD cameras. The electronic circuit implements a dynamic threshold method
