Perceptual masking: Peripheral vs central factors [PDF]

open access: yesPerception & Psychophysics, 1971
Perceptual masking was studied under binocular and dichoptic conditions in order to separate peripheral and central interference effects. Under binocular conditions, when the test flash (TF) and the blanking flash (BF) fell on both retinas, both retroactive and proactive masking were demonstrated. Under dichoptic conditions, when the TF fell on one eye

Perceptual Image Fusion Using Wavelets [PDF]

open access: yesIEEE Transactions on Image Processing, 2017
A perceptual image fusion method is proposed that employs explicit luminance and contrast masking models. These models are combined to give the perceptual importance of each coefficient produced by the dual-tree complex wavelet transform of each input ...

A new empirical challenge for local theories of consciousness [PDF]

open access: yes, 2021
Local theories of consciousness state that one is conscious of a feature if it is adequately represented and processed in sensory brain areas, given some background conditions.

A perceptual evaluation of 3D unsharp masking [PDF]

open access: yesSPIE Proceedings, 2009
Much research has gone into developing methods for enhancing the contrast of displayed 3D scenes. In the current study, we investigated the perceptual impact of an algorithm recently proposed by Ritschel et al.1 that provides a general technique for enhancing the perceived contrast in synthesized scenes.

Investigating the influence of masker and target properties on the dynamics of perceptual awareness under informational masking.

open access: yesPLoS ONE, 2023
Informational masking has been investigated using the detection of an auditory target embedded in a random multi-tone masker. The build-up of the target percept is influenced by the masker and target properties.

Effects of presentation level on speech-on-speech masking by voice-gender difference and spatial separation between talkers

open access: yesFrontiers in Neuroscience, 2023
Many previous studies have reported that speech segregation performance in multi-talker environments can be enhanced by two major acoustic cues: (1) voice-characteristic differences between talkers; (2) spatial separation between talkers.

Perceptual redundancy model for compression of screen content videos

open access: yesIET Image Processing, 2022
Screen content video (SCV) consists primarily of text areas, computer graphics and other computer‐generated content and possesses unique perceptual characteristics.

Perceptual restoration of masked speech in human cortex [PDF]

open access: yesNature Communications, 2016
AbstractHumans are adept at understanding speech despite the fact that our natural listening environment is often filled with interference. An example of this capacity is phoneme restoration, in which part of a word is completely replaced by noise, yet listeners report hearing the whole word.

Masking of figure-ground texture and single targets by surround inhibition: a computational spiking model. [PDF]

open access: yesPLoS ONE, 2012
A visual stimulus can be made invisible, i.e. masked, by the presentation of a second stimulus. In the sensory cortex, neural responses to a masked stimulus are suppressed, yet how this suppression comes about is still debated.

JND-Based Perceptual Video Coding for 4:4:4 Screen Content Data in HEVC [PDF]

open access: yes, 2018
The JCT-VC standardized Screen Content Coding (SCC) extension in the HEVC HM RExt + SCM reference codec offers an impressive coding efficiency performance when compared with HM RExt alone; however, it is not significantly perceptually optimized.
