JPEG2000 Encoding With Perceptual Distortion Control

open access: yesIEEE Transactions on Image Processing, 2006
In this paper, a new encoding approach is proposed to control the JPEG2000 encoding in order to reach a desired perceptual quality. The new method is based on a vision model that incorporates various masking effects of human visual perception and a ...

On Perceptual Distortion Minimization and Nonlinear Least-Squares Frequency Estimation [PDF]

open access: yesIEEE Transactions on Audio Speech and Language Processing, 2006
In this paper, we present a framework for perceptual error minimization and sinusoidal frequency estimation based on a new perceptual distortion measure, and we state its optimal solution.

Perceptual image distortion

Proceedings of 1st International Conference on Image Processing, 2002
In this paper, we present a perceptual distortion measure that predicts image integrity far better than mean-squared error. This perceptual distortion measure is based an a model of human visual processing that fits empirical measurements of the psychophysics of spatial pattern detection. The model of human visual processing proposed involves two major

Experience of Perceptual Distortion as a Source of Anxiety

Archives of Neurology And Psychiatry, 1958
Important in psychological growth is the emergence of cognitive functions through which external events are apprehended more in terms of perceptual field characteristics and less as outward representations of inner drive processes. As Freud originally proposed, 4 and Rapaport has recently developed at length, 14 the trend from primary toward secondary ...

Perceptual Distortions in Visual-Evoked Potentials

American Journal of Ophthalmology, 1981
We tested ten healthy men, ranging in age from 24 to 55 years, to determine whether "drifting" of a fixation target during pattern-stimulus testing was the result of stimulus-induced ocular movements or a purely perceptual response with no oculomotor basis.
