INVERSE MONOIDS OF DOT-DEPTH TWO
International Journal of Algebra and Computation, 1993It 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.

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).

The inverse problem of depth dose curve estimation
Physics in Medicine and Biology, 1997The 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.

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.

Water depth inversion from satellite dataset
2014 IEEE Geoscience and Remote Sensing Symposium, 2014Within 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, 1981The 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

Depth of Ankle Inversion and Discrimination of Foot Positions
Perceptual and Motor Skills, 2010Ankle inversion injuries are common, yet little is known about the error associated with different positions as inversion depth increases. In this study, absolute judgments made without feedback were used to measure discrimination of different extents of ankle inversion which arose from active movements made to physical stops by 20 self-reported right

Deghosting through Depth Domain Inversion
Proceedings, 2015We describe a method for performing deghosting in the image domain. The method consists of a multi-dimensional deterministic deconvolution of a standard migrated image using non-Hessian form operators. The operators, created by modelling with ghost effects followed by standard migration, compensate for both dip-dependent illumination and ghost effects,

What's in a Face? The Role of Depth Undulations in Three-Dimensional Depth-Inversion Illusions
Perception, 2014Upright hollow human faces produce among the strongest depth-inversion illusions (DIIs), but why? We considered the role of depth undulations by comparing four types of hollow objects: An ellipsoid, a human mask, and two symmetric ‘Martian’ masks, which wavered in depth like the human mask but which lacked face-like features.

Impaired binocular depth inversion in patients with alcohol withdrawal
Journal of Psychiatric Research, 1996Binocular depth inversion represents an illusion of visual perception. Such inversion does not occur in all cases, especially when objects with a higher degree of familiarity (e.g. photographs of faces) are displayed. Cognitive factors are assumed to override the binocular disparity cues of stereopsis.
