Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

open access: yes, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

REDUCED BINOCULAR DEPTH INVERSION IN PATIENTS WITH ALCOHOLISM [PDF]

open access: yesAlcohol and Alcoholism, 1998
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 higher degree of familiarity (e.g. photographs of faces) are displayed.

Estimating Snow Depth Using Multi-Source Data Fusion Based on the D-InSAR Method and 3DVAR Fusion Algorithm

open access: yesRemote Sensing, 2017
Snow depth is a general input variable in many models of agriculture, hydrology, climate, and ecology. However, there are some uncertainties in the retrieval of snow depth by remote sensing.

Analytic Inversion of Emission Lines of Arbitrary Optical Depth for the Structure of Supernova Ejecta [PDF]

open access: yes, 2000
We derive a method for inverting emission line profiles formed in supernova ejecta. The derivation assumes spherical symmetry and homologous expansion (i.e., $v(r) \propto r$), is analytic, and even takes account of occultation by a pseudo-photosphere ...

Dense RGB-D visual odometry using inverse depth [PDF]

open access: yesRobotics and Autonomous Systems, 2016
In this paper we present a dense visual odometry system for RGB-D cameras performing both photometric and geometric error minimisation to estimate the camera motion between frames. Contrary to most works in the literature, we parametrise the geometric error by the inverse depth instead of the depth, which translates into a better fit of the ...

A Noise De-Correlation Based Sun Glint Correction Method and Its Effect on Shallow Bathymetry Inversion

open access: yesRemote Sensing, 2022
Sun glint on the sea surface is the unavoidable noise in optical remote sensing images. Water depth retrieval based on optical remote sensing images is vulnerable to sun glint contamination.

Ground-based detections of thermal emission from CoRoT-1b and WASP-12b [PDF]

open access: yes, 2011
We report a new detection of the H-band thermal emission of CoRoT-1b and two confirmation detections of the Ks-band thermal emission of WASP-12b at secondary eclipses. The H-band measurement of CoRoT-1b shows an eclipse depth of 0.145%\pm0.049% with a 3-{

Unmanned Aerial Vehicle Depth Inversion to Monitor River-Mouth Bar Dynamics

open access: yesRemote Sensing, 2021
Monitoring the morphological evolution of a river-mouth bar is of both practical and scientific importance. A large amount of sediment is transported from a river to surrounding littoral cells via a deltaic bar after an extreme weather event. However, it

X-ray image reconstruction from a diffraction pattern alone

open access: yes, 2003
A solution to the inversion problem of scattering would offer aberration-free diffraction-limited 3D images without the resolution and depth-of-field limitations of lens-based tomographic systems. Powerful algorithms are increasingly being used to act as

Spectropolarimetric NLTE inversion code SNAPI

open access: yes, 2018
Inversion codes are computer programs that fit a model atmosphere to the observed Stokes spectra, thus retrieving the relevant atmospheric parameters. The rising interest in the solar chromosphere, where spectral lines are formed by scattering, requires ...
