Individual differences in metacontrast masking are enhanced by perceptual learning
Consciousness and Cognition, 2009 In vision research metacontrast masking is a widely used technique to reduce the visibility of a stimulus. Typically, studies attempt to reveal general principles that apply to a large majority of participants and tend to omit possible individual ...

Efficient wavelet‐based perceptual watermark masking for robust fingerprint image watermarking
IET Image Processing, 2014 In this study, a robust wavelet-based fingerprint image watermarking scheme using an efficient just perceptual weighting (JPW) model has been proposed.

Just Noticeable Difference Model for Images with Color Sensitivity
Sensors, 2023 The just noticeable difference (JND) model reflects the visibility limitations of the human visual system (HVS), which plays an important role in perceptual image/video processing and is commonly applied to perceptual redundancy removal.

Chinese Character Processing in Visual Masking
Frontiers in Psychology, 2022 It has not been clarified if attention influences perception of targets in visual masking. Three forms of common masks (random pattern, para-/metacontrast, and four dots) were thus chosen in the present study and presented with character targets in three

PLoS 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.

Frontiers 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.

Exploiting entropy masking in perceptual graphic rendering [PDF]
Signal Processing: Image Communication, 2015 Abstract Since the human visual system (HVS) is the ultimate appreciator of most photorealistically rendered images, rendering process can be accelerated by exploiting the properties of the HVS. According to the concept of entropy masking, the HVS is not sensitive to visual distortions in unstructured visual signals.

Perceptual redundancy model for compression of screen content videos
IET 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]
Nature 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.
