Various image processing applications exploit a model of the human visual system (HVS). One element of HVSmodels describes the masking-effect, which is typically parameterized by psycho-visual experiments that employ superimposed sinusoidal stimuli. Those stimuli are oversimplified with respect to real images and can capture only very elementary maskingeffects. To overcome these limitations a n...

UNLABELLED A 1 degrees -spot was flashed up on a screen, followed by a snugly fitting annular mask. We measured the amount of masking as a function of stimulus luminance. The surround was always mid-gray, the masking ring was either black or white, and the luminance of the spot target ranged from 0% to 100% of white in 4% steps. Observers reported the apparent lightness of the masked spot by ad...

Visual masking has been used both to study characteristics of visual perception and as a tool to explore other aspects of cognition (see Breitmeyer & Ögmen (2000) and Enns & Di Lollo (2000) for recent reviews). Given the long history and strong interest in masking, it is significant when fundamentally new properties of masking are discovered. In a series of publications, Enns and Di Lollo (1997...

In this study, targets were nonsense sentences spoken by a Chinese female, and maskers were nonsense sentences spoken by other 1, 2, 3, or 4 Chinese females. All stimuli were presented by two spatially separated loudspeakers. Using the precedence effect, manipulation of the delay between the two loudspeakers for the masker determined whether the target and masker were perceived as coming from t...

ION EXCHANGE RESIN AS AN IMPOSING METHOD FOR TASTE MASKING: A REVIEW A. M. Suthar* and M. M. Patel Saraswati School of Pharmacy, Ranela, Gujarat, India Kalol Institute of Pharmacy, Kalol, Gujatat, India ABSTRACT Taste masking becomes a pre-requisite for bitter drugs to improve the patient compliance especially in the pediatric and geriatric population. Conventional taste masking techniques such...

Listeners’ ability to understand a target speaker in the presence of one or more simultaneous competing speakers is subject to two types of masking: Energetic and informational. Energetic masking occurs when target and interfering signals overlap in time and frequency resulting in portions of target becoming inaudible. Informational masking occurs when the listener is unable to segregate the ta...
