Lensless Multispectral Camera Based on a Coded Aperture Array [PDF]

open access: yesSensors, 2021
Multispectral imaging can be applied to water quality monitoring, medical diagnosis, and other applications, but the principle of multispectral imaging is different from the principle of hyper-spectral imaging. Multispectral imaging is generally achieved

Drone-Aided Detection of Weeds: Transfer Learning for Embedded Image Processing

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
In this article, we address the problem of hogweed detection using a drone equipped with red, green, blue (RGB) and multispectral cameras. We study two approaches: 1) offline detection running on the orthophoto of the area scanned within the mission and ...

Single-shot detection of 8 unique monochrome fringe patterns representing 4 distinct directions via multispectral fringe projection profilometry

open access: yesScientific Reports, 2021
Spatial resolution in three-dimensional fringe projection profilometry is determined in large part by the number and spacing of fringes projected onto an object. Due to the intensity-based nature of fringe projection profilometry, fringe patterns must be
