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

Sensors, 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 ...

Single-shot 3D coherent diffractive imaging of core-shell nanoparticles with elemental specificity. [PDF]

, 2018
We report 3D coherent diffractive imaging (CDI) of Au/Pd core-shell nanoparticles with 6.1 nm spatial resolution with elemental specificity. We measured single-shot diffraction patterns of the nanoparticles using intense x-ray free electron laser pulses.

Three-dimensional block matching using orthonormal tree-structured haar transform for multichannel images [PDF]

, 2020
Multichannel images, i.e., images of the same object or scene taken in different spectral bands or with different imaging modalities/settings, are common in many applications.

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

European 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.

Video-rate computational super-resolution and integral imaging at longwave-infrared wavelengths [PDF]

, 2017
We report the first computational super-resolved, multi-camera integral imaging at long-wave infrared (LWIR) wavelengths. A synchronized array of FLIR Lepton cameras was assembled, and computational super-resolution and integral-imaging reconstruction ...

3D Images

, 2021
AbstractSpatial (3D) image construction from imaging plate (IP) images and the development of the microautography (MAR) method were presented. A rice grain was sliced every 5 μm, IP images were taken for successive slices, and the series of 2D images acquired by an IP were used to construct 3D images.

3D-Imaging Endoscopy Through Electronic Focusing

IEEE 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.
