Perceptual Templates Improvement through Action Video Game Playing and Comparison to Perceptual Learning

open access: yesi-Perception, 2011
Action video game playing substantially improves visual performance; however, the source of this improvement remains unclear. Here we use the equivalent external noise technique to characterize the mechanism by which action video games may facilitate ...

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‐

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 ...

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

Correlation Noise Estimation in Distributed Video Coding [PDF]

open access: yes, 2011
Video compression is achieved by exploiting spatial and temporal correlations in the frame sequence. A frame is typically predicted by the encoder from previously coded information (such as blocks and/or frames), and the residual between the frame and its prediction is entropy coded.

Video Enhancement Using Adaptive Spatio-Temporal Connective Filter and Piecewise Mapping

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
This paper presents a novel video enhancement system based on an adaptive spatio-temporal connective (ASTC) noise filter and an adaptive piecewise mapping function (APMF).

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 ...
