PLoS ONE, 2019 The neural representation and perceptual salience of tonal signals presented in different noise maskers were investigated. The properties of the maskers and signals were varied such that they produced different amounts of either monaural masking release,

A Neural Network Model of Inhibitory Processing in Subliminal Priming [PDF]
, 2006 Masked Priming Experiments have revealed a precise set of facilitatory and inhibitory visual-motor control processes. Most notably, inhibitory effects have been identified in which prime-target compatibility induces performance costs and prime-target ...

Spectral-PQ: A Novel Spectral Sensitivity-Orientated Perceptual Compression Technique for RGB 4:4:4 Video Data [PDF]
arXiv, 2022 There exists an intrinsic relationship between the spectral sensitivity of the Human Visual System (HVS) and colour perception; these intertwined phenomena are often overlooked in perceptual compression research. In general, most previously proposed visually lossless compression techniques exploit luminance (luma) masking including luma spatiotemporal ...

Quality assessment methods for perceptual video compression [PDF]
, 2021 This paper describes a quality assessment model for perceptual video compression applications (PVM), which stimulates visual masking and distortion-artefact perception using an adaptive combination of noticeable distortions and blurring artefacts. The method shows significant improvement over existing quality metrics based on the VQEG database, and ...

Perceptual thresholds for the effects of room modes as a function of modal decay [PDF]
, 2015 Room modes cause audible artefacts in listening environments. Modal control approaches have emerged in scientific literature over the years and, often, their performance is measured by criteria that may be perceptually unfounded.

Image Inpainting by End-to-End Cascaded Refinement with Mask Awareness [PDF]
, 2021 Inpainting arbitrary missing regions is challenging because learning valid features for various masked regions is nontrivial. Though U-shaped encoder-decoder frameworks have been witnessed to be successful, most of them share a common drawback of mask unawareness in feature extraction because all convolution windows (or regions), including those with ...

Why Are Deep Representations Good Perceptual Quality Features?
, 2020 Recently, intermediate feature maps of pre-trained convolutional neural networks have shown significant perceptual quality improvements, when they are used in the loss function for training new networks.

Visual Attention Guided Pixel-Wise Just Noticeable Difference Model
IEEE Access, 2019 The just noticeable difference (JND) models in pixel domain are generally composed of luminance adaptation (LA) and contrast masking (CM), which takes edge masking (EM) and texture masking (TM) into consideration.

Color Video JND Model Using Compound Spatial Masking and Structure-Based Temporal Masking
IEEE Access, 2020 In order to provide high transmission efficiency and visual quality for the color image/video in internet, effective estimation of its inherent just noticeable distortion (JND) is continuously an important topic.
