A Convolutional Neural Network with Spatial Location Integration for Nearshore Water Depth Inversion [PDF]

open access: yesSensors, 2023
Nearshore water depth plays a crucial role in scientific research, navigation management, coastal zone protection, and coastal disaster mitigation. This study aims to address the challenge of insufficient feature extraction from remote sensing data in ...

Depth inversion with a 3D structure influences brightness perception. [PDF]

open access: yesPLoS ONE, 2019
Whether or not depth perception influences brightness and/or lightness perception has been repeatedly discussed, and some studies have emphasized its importance. In addition, a small number of studies have empirically tested and shown the effect of depth

Depth model building by constrained magnetotelluric inversion

open access: yesAnnals of Geophysics, 2002
In this paper we describe an approach aimed at integrating seismic and magnetotelluric data in a complex geological setting, characterised by thrust structures, in Southern Apennine, Southern Italy.

Temperature inversions in China derived from sounding data from 1976 to 2015

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2021
Temperature inversions inhibit the transfer of momentum, heat and moisture in the atmosphere and have led to severe air pollution in China. This study investigated the spatiotemporal variation in temperature inversions in China using sounding data for ...

A Self-Adaptive Method for Mapping Coastal Bathymetry On-The-Fly from Wave Field Video

open access: yesRemote Sensing, 2021
Mapping coastal bathymetry from remote sensing becomes increasingly more attractive for the coastal community. It is facilitated by a rising availability of drone and satellite data, advances in data science, and an open-source mindset.

Delayed Inverse Depth Monocular SLAM [PDF]

open access: yesIFAC Proceedings Volumes, 2008
The 6-DOF monocular camera case possibly represents the harder variant in the context of simultaneous localization and mapping problem. In the last years, several advances have been appeared in this area; however the application of these techniques to real world applications it’s difficult so far.

Video-Based Nearshore Bathymetric Inversion on a Geologically Constrained Mesotidal Beach during Storm Events

open access: yesRemote Sensing, 2022
Although geologically constrained sandy beaches are ubiquitous along wave-exposed coasts, there is still a limited understanding of their morphological response, particularly under storm conditions, which is mainly due to a critical lack of nearshore ...

Geophysical and Sedimentological Investigations Integrate Remote-Sensing Data to Depict Geometry of Fluvial Sedimentary Bodies: An Example from Holocene Point-Bar Deposits of the Venetian Plain (Italy)

open access: yesRemote Sensing, 2020
Over the past few millennia, meandering fluvial channels drained coastal landscapes accumulating sedimentary successions that today are permeable pathways.

Inverse Depth to Depth Conversion for Monocular SLAM [PDF]

open access: yesProceedings 2007 IEEE International Conference on Robotics and Automation, 2007
Recently it has been shown that an inverse depth parametrization can improve the performance of real-time monocular EKF SLAM, permitting undelayed initialization of features at all depths. However, the inverse depth parametrization requires the storage of 6 parameters in the state vector for each map point.
