Reduced binocular depth inversion in schizophrenic patients

Schizophrenia Research, 2002
Binocular depth inversion represents an illusion of visual perception, serving to invert the perception of implausible hollow objects, e.g. a hollow face into a normal face. Such inversion occurs frequently, especially when objects with a high degree of familiarity (e.g. photographs of faces) are displayed.

Inverse Depth Parametrization

2011
This chapter presents a parametrization for point features within monocular SLAM which permits efficient and accurate representation of uncertainty during undelayed initialisation and beyond, all within the standard EKF (Extended Kalman Filter).

Gravity inversion with depth normalization

2020
<p>Actually the most common method of gravity data interpretation is a manual fitting method. In this case, the density model is divided into many polygons with constant density and each polygon is editing manually by interpreter.

Q-compensation Through Depth Domain Inversion

Proceedings, 2015
We propose a new method that enables Q-compensation after depth imaging and within the framework of depth domain inversion. The approach relies on deterministic operators that capture the dip-dependent amplitude and phase anelastic effects seen by the waves as they propagate through a 3D anelastic medium, and corrects for them by inversion in the image

INVERSE MONOIDS OF DOT-DEPTH TWO

International Journal of Algebra and Computation, 1993
It is shown that the pseudovariety of inverse monoids of dot-depth two is decidable and is equal to the Malcev product of the pseudovariety generated by the 5 element Brandt semigroup and the variety of semilattices.

Water depth inversion from satellite dataset

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
Within an effort to estimate near-shore bathymetry from satellite scenes, a method based on wave celerity and wavelength estimation is developed. These wave characteristics are extracted from SPOT-5 panchromatic and multispectral scenes. The method allows us to associate the wavelength and the celerity of the same detected wave and to estimate the ...

Depth Perception in Linear and Inverse Perspective Pictures

Perception, 1981
The range of pictorial depth perception was tested with four pictures from the repertoire of European art, rather than the customary line drawings or photographs. These pictures included those rendered in linear perspective and inverse perspective, as well as those with different degrees of depth. Using Pandora’ Box, the subjects were asked to place a

The inverse problem of depth dose curve estimation

Physics in Medicine and Biology, 1997
The inverse problem of the depth dose curve is formulated and a proposition for its solution is presented. The solution is based on the approximation of the observation equation with a numerical quadrature operator and the regularization of this inverse problem with a smoothness side constraint.

Reduced binocular depth inversion in regular cannabis users

Pharmacology Biochemistry and Behavior, 2003
The binocular depth inversion illusion (BDII) has been shown to be a sensitive measure of impaired visual information processing under conditions including cannabinoid-intoxicated states, alcohol withdrawal, sleep deprivation, and in patients with positive symptoms of schizophrenia.

AVO inversion on depth migrated traces

SEG Technical Program Expanded Abstracts 2001, 2001
It is generally recognized that avo inversion is better conducted on depth migrated traces, although it is not often done because of computational costs and the fact that it may provide only marginal improvement in regions of low dip and small lateral velocity gradients.
