Integrated Airborne LiDAR Data and Imagery for Suburban Land Cover Classification Using Machine Learning Methods

open access: yesSensors, 2019
It is valuable to study the land use/land cover (LULC) classification for suburbs. The fusion of Light Detection and Ranging (LiDAR) data and aerial imagery is often regarded as an effective method for the LULC classification; however, more in-depth ...

Resorption of retromolar bone grafts after alveolar ridge augmentation—volumetric changes after 12 months assessed by CBCT analysis

open access: yesInternational Journal of Implant Dentistry, 2021
In this pilot study, a volumetric analysis of retromolar onlay bone grafts over a period of 12 months was conducted, using repeated CBCT imaging combined with automated image registration.

3D imaging of a nuclear reactor using muography measurements with Micromegas detectors [PDF]

open access: yesEPJ Web of Conferences, 2023
Transmission muography is a non-invasive and non-destructive imaging method which allows to estimate the integrated density of a volume in a given direction (also referred as opacity).

3D imaging, 3D printing and 3D virtual planning in endodontics [PDF]

open access: yesClinical Oral Investigations, 2018
The adoption and adaptation of recent advances in digital technology, such as three-dimensional (3D) printed objects and haptic simulators, in dentistry have influenced teaching and/or management of cases involving implant, craniofacial, maxillofacial, orthognathic and periodontal treatments.

On the cohomology of 3D digital images

open access: yesDiscrete Applied Mathematics, 2005
We propose a method for computing the cohomology ring of three--dimensional (3D) digital binary-valued pictures. We obtain the cohomology ring of a 3D digital binary--valued picture $I$, via a simplicial complex K(I)topologically representing (up to isomorphisms of pictures) the picture I.

An in vivo study to investigate an original intramedullary bone graft harvesting technology

open access: yesEuropean Journal of Medical Research, 2023
Background Harvesting bone graft (BG) from the intramedullary canal to treat bone defects is largely conducted using the Reamer–Irrigator–Aspirator (RIA) system.

Linearly modulated multi-focal diffractive lens for multi-sheet excitation of flow driven samples in a light-sheet fluorescence microscope

open access: yesJournal of the European Optical Society-Rapid Publications, 2023
Light sheet fluorescence microscope with single light sheet illumination enables rapid 3D imaging of living cells. In this paper we show the design, fabrication and characterization of a diffractive optical element producing several light sheets along a ...

3D Computational Ghost Imaging [PDF]

open access: yesThe Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013
Computational ghost imaging retrieves the spatial information of a scene using a single pixel detector. By projecting a series of known random patterns and measuring the back reflected intensity for each one, it is possible to reconstruct a 2D image of the scene.

3D-Imaging Endoscopy Through Electronic Focusing

open access: yesIEEE Photonics Journal
Conventional endoscopic systems provide two-dimensional images of three-dimensional structures. Real depth information is lost in these systems. Therefore, depth perception relies uniquely on monocular cues, such as occlusions, shadows or motion parallax.
