Loudspeaker linearization using perceptual distortion measures
The Thrity-Seventh Asilomar Conference on Signals, Systems & Computers, 2003, 2004Volterra filters are used to model loudspeaker nonlinearities. To compensate for the nonlinearities of the electro-acoustic conversion, the signal is passed through a predistortion filter placed between the audio signal source and the loudspeaker. Predistortion filters based on the inverse of second order Volterra filter increase the signal to noise ...

Image recompression and perceptual distortion analysis
SPIE Proceedings, 2004The aim of this research is to recompress the JPEG standard images in order to minimize the storage and/or communications bandwidth requirements. In our approach, we convert existing JPEG images into JPEG 2000 images. The proposed image restoration method is applied to improve the visual quality when the bit rate becomes low and visually annoying ...

Perceptual distortions in dynamic visual displays
Annual Meeting Optical Society of America, 1985A rotating vector, generated on a high resolution monitor, can appear to break into multiple images away from the point of fixation. This phenomenon was studied by measuring the highest angular velocity that was accompanied by the perception of a single, rotating line. The main findings were that higher angular velocities could be tolerated with higher

Gratings That Induce Perceptual Distortions Mask Superimposed Targets
Perception, 1996Masking is known to depend upon the relationship between the spatial-frequency content of target and mask. This relationship has been held constant in three experiments in order to investigate the separate contribution of the spatial parameters of the mask, in this case a grating with square-wave luminance profile.

Perceptually Induced Distortions in Cognitive Maps
2005Cities on a map that are directly connected by a route are judged closer than unconnected cities. This route effect has been attributed to memory distortions induced by the integration of map information with high-level knowledge about implications of route connections.

Perceptual Distortions When Driving in Fog
Traffic And Transportation Studies (2002), 2002Fog doubles the risk of accidents and modifies driving behavior in a way that leads to greater risk-taking. In a series of experiments performed in a fog chamber and on a driving simulator, we looked at the perceptive difficulties that drivers may encounter under such conditions.
