Spatio-temporal Functional Regression on Paleo-ecological Data [PDF]

arXiv, 2008
The influence of climate on biodiversity is an important ecological question. Various theories try to link climate change to allelic richness and therefore to predict the impact of global warming on genetic diversity. We model the relationship between genetic diversity in the European beech forests and curves of temperature and precipitation ...

Automated corrosion surface quantification in steel transmission towers using UAV photogrammetry and deep convolutional neural networks

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Corrosion in steel transmission towers poses a challenge to structural integrity and safety, requiring efficient detection methods. Traditional visual inspections are unsustainable due to the complexity and volume of structures. Their manual, qualitative, and subjective nature often leads to inconsistencies in maintenance planning.

Complete Model for Automatic Object Detection and Localisation on Aerial Images using Convolutional Neural Networks

Journal of Communications Software and Systems, 2018
In this paper, a novel approach for an automatic object detection and localisation on aerial images is proposed. Proposed model does not use ground control points (GCPs) and consists of three major phases.

A Novel Georeferenced Dataset for Stereo Visual Odometry [PDF]

arXiv, 2013
In this work, we present a novel dataset for assessing the accuracy of stereo visual odometry. The dataset has been acquired by a small-baseline stereo rig mounted on the top of a moving car. The groundtruth is supplied by a consumer grade GPS device without IMU.

Georeferencing Brazilian Highway Addresses

Journal of Geographic Information System, 2016
The usage of georeferencing as a search tool has suffered a massification after the diffusion of technologies developed by Google and Microsoft. In this context, problems related to the location of properties situated on highways are becoming quite usual in Brazil, because properties registration in highway is permitted in the country and this ...

Thermal Infrared Image Georeferencing using an Ensemble of Land Cover Predictions [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Precise georeferencing of remote sensing data is usually implemented in a post-processing fashion and is a crucial step for Earth observation applications such as change detection, natural hazard management, and ground target tracking. It is particularly

Knowing the past for managing the present: A comparison between historical cartography and satellite images for the study of Rome's city centre [PDF]

, 2013
The idea of this paper, develops from the consideration that, since the second half of the XXth century, urban planning of Italian historical centers seems constrained by the fear of compromising the architectures of the past.

An Optimal Algorithm for Changing from Latitudinal to Longitudinal Formation of Autonomous Aircraft Squadrons [PDF]

arXiv, 2017
This work presents an algorithm for changing from latitudinal to longitudinal formation of autonomous aircraft squadrons. The maneuvers are defined dynamically by using a predefined set of 3D basic maneuvers. This formation changing is necessary when the squadron has to perform tasks which demand both formations, such as lift off, georeferencing ...

A joint estimation approach for monotonic regression functions in general dimensions

Scandinavian Journal of Statistics, EarlyView.
Abstract Regression analysis under the assumption of monotonicity is a well‐studied statistical problem and has been used in a wide range of applications. However, there remains a lack of a broadly applicable methodology that permits information borrowing, for efficiency gains, when jointly estimating multiple monotonic regression functions.
