Perceptual identification and discrimination of phase distortions
ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Experimental results on the audibility of phase distortion produced by minimum-phase 4kHz and 15 kHz anti-alias filters are reported. Numerous impulse response pairs with identical spectral magnitudes but linear-phase and minimum-phase responses were compared by five test subjects who listened dichotically on earphones.

Typical perceptual organization in autism: Perceptual grouping and spatial distortion
Autism Research, 2019The extensive literature on global–local processing in people with autism spectrum disorder (ASD) has recently shifted from arguing for a processing impairment among those with ASD to positing an attenuated preference for global processing. One suggestion is that the fast extraction of the global gist is less efficient in ASD, in contrast to the ...

Adaptive Image Coding With Perceptual Distortion Control
IEEE Transactions on Image Processing, 2002This paper presents a discrete cosine transform (DCT)-based locally adaptive perceptual image coder, which discriminates between image components based on their perceptual relevance for achieving increased performance in terms of quality and bit rate. The new coder uses a locally adaptive perceptual quantization scheme based on a tractable perceptual ...

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.

Studies in Perceptual Distortion
A.M.A. Archives of General Psychiatry, 1960Introduction A series of studies has been planned to test the hypotheses (1) that whenever perceptual distortions are induced, by whatever means, the distorting process begins with changes in the orientational percepts—of time, space, body boundary, movement in space, and the gravity-bound feeling of weight—and that these changes proceed in a regular,

PERCEPTUAL DISTORTION INDUCED BY REASONING
British Journal of Psychology, 1966The aim of this investigation was to compare the effects of three different degrees of expectancy on the perception of relative length. It was assumed that expectancy would be ( a ) maximal when erroneous information about the relative length of two equal lines was deduced

Perceptual blocking distortion measure for digital video
SPIE Proceedings, 2000In this paper, a perceptual blocking distortion metric for block-based transform coded digital video is proposed. The metric is based on a spatio-temporal multichannel vision model to calculate the Just Noticeable Distortion (JND) map. The blocking dominant regions are segmented after the spatio-temporal decomposition and the JNDs in these regions are ...

Perceptual distortions in the neural representation of visual space
Experimental Brain Research, 1999The visual mechanism by which human observers determine the separation between objects has long been of interest. This study examines the extent to which separation in visual space can be misperceived in foveal and extrafoveal vision. Foveally, vertical separations were consistently overestimated relative to horizontal separations, a result which is ...

A perceptual quality based rate distortion model
2012 Fourth International Workshop on Quality of Multimedia Experience, 2012Rate and distortion models (R-D models) are important for current image/video encoders. They can help encoders to find the best encoding parameters for improving encoding performance quickly and effectively. However, most of the existing R-D models are based on mean square error (MSE). For the purpose of achieving better perceptual quality in encoding,
