What's in a Mask? Information Masking with Forward and Backward Visual Masks

Quarterly Journal of Experimental Psychology, 2011
Three experiments tested how the physical format and information content of forward and backward masks affected the extent of visual pattern masking. This involved using different types of forward and backward masks with target discrimination measured by percentage correct in the first experiment (with a fixed target duration) and by an adaptive ...

Energetic Masking and Masking Release

2017
Masking is of central interest in the cocktail party problem, because interfering voices may be sufficiently intense or numerous to mask the voice to which the listener is attending, rendering its discourse unintelligible. The definition of energetic masking is problematic, but it may be considered to consist of effects by which an interfering sound ...

Contrast masking in human vision.

Journal of the Optical Society of America, 1980
Contrast masking was studied psychophysically. A two-alternative forced-choice procedure was used to measure contrast thresholds for 2.0 cpd sine-wave gratings in the presence of masking sine-wave gratings.

Mask in the Mirror: The Living Mask Illusion

Perception, 2011
Self-perception in a mirror is a dynamic process involving self-motion and autonomous self-exploratory control of facial poses and expressions.In a previous work, apparitions of strange faces in the mirror were experienced, often as other beings appearing in place of one's own face.

Improved wavelet-based watermarking through pixel-wise masking

IEEE Transactions on Image Processing, 2001
A watermarking algorithm operating in the wavelet domain is presented. Performance improvement with respect to existing algorithms is obtained by means of a new approach to mask the watermark according to the characteristics of the human visual system ...

Informational and energetic masking effects in the perception of two simultaneous talkers.

Journal of the Acoustical Society of America, 2001
Although most recent multitalker research has emphasized the importance of binaural cues, monaural cues can play an equally important role in the perception of multiple simultaneous speech signals.

“The mask who wasn’t there”: Visual masking effect with the perceptual absence of the mask.

Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015
Does a visual mask need to be perceptually present to disrupt processing? In the present research, we proposed to explore the link between perceptual and memory mechanisms by demonstrating that a typical sensory phenomenon (visual masking) can be replicated at a memory level.

Seeing (through) masks: An exploration of masks and mask making

Visual Anthropology, 2000
In the form of a collage I juxtapose my experience of mask‐making with various interpretations of the nature and meaning of masks in order to explore the questions of whether masks can have meaning for those outside the culture of origin and whether encountering cultural artifacts like masks can enhance our own self‐understanding. I conclude, with some

Image enhancement via adaptive unsharp masking

IEEE Transactions on Image Processing, 2000
This paper presents a new method for unsharp masking for contrast enhancement of images. The approach employs an adaptive filter that controls the contribution of the sharpening path in such a way that contrast enhancement occurs in high detail areas and

EUV Mask and Mask Metrology

2009
For the successful implementation of extreme ultraviolet lithography (EUVL) technology for the future semiconductor fabrication process, EUV mask technology is considered to be one of the most critical issues. Since EUV light is strongly absorbed by most materials, reflective optics is applied to all the optical components, including the mask.
