Data Hiding in Perceptually Masked OpenEXR Image
2019 IEEE 21st International Workshop on Multimedia Signal Processing (MMSP), 2019 High dynamic range (HDR) imaging is able to capture and display significantly more colors when compared to the legacy imaging technology. Recently, HDR environment is gaining popularity and becoming common in our daily life, which resulted in the growing number of HDR images.

A perceptual masking approach for noise robust speech recognition [PDF]
EURASIP Journal on Audio, Speech, and Music Processing, 2012 This article describes a modified technique for enhancing noisy speech to improve automatic speech recognition (ASR) performance. The proposed approach improves the widely used spectral subtraction which inherently suffers from the associated musical noise effects. Through a psychoacoustic masking and critical band variance normalization technique, the

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.

An Interactive Perceptual Rendering Pipeline using Contrast and Spatial Masking [PDF]
, 2007 International audienceWe present a new perceptual rendering pipeline which takes into account visual masking due to contrast and spatial frequency. Our framework predicts inter-object, scene-level masking caused by partial occlusion and shadows.

The plasticity of the human perceptual systems in processing auditory- and spatial-frequencies [PDF]
, 2009 A common technique in research on visual and auditory perception is to embed stimuli in noise. The traditional assumption is that, when noisy stimuli are repeatedly presented to an observer, each noise component remains equally unpredictable.
