Coupled harmonic oscillators model with two connected point masses for application in photo-induced force microscopy

open access: yesNanophotonics, 2023
To comprehensively describe the operation of photo-induced force microscopy (PiFM), we have developed a model based on coupled harmonic oscillators. This model features two point masses connected by massless elastic wires, offering greater intuitiveness ...

Hyperspectral Pansharpening: A Review [PDF]

open access: yesIEEE Geoscience and Remote Sensing Magazine, 2015
Pansharpening aims at fusing a panchromatic image with a multispectral one, to generate an image with the high spatial resolution of the former and the high spectral resolution of the latter. In the last decade, many algorithms have been presented in the literature for pansharpening using multispectral data.

A Simplified 2D-3D CNN Architecture for Hyperspectral Image Classification Based on Spatial–Spectral Fusion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Convolutional neural networks (CNN) have led to a successful breakthrough for hyperspectral image classification (HSIC). Due to the intrinsic spatial-spectral specificities of a hyperspectral cube, feature extraction with 3-D convolution operation is a ...

Automatic Detection of Aquatic Weeds: A Case Study in the Guadiana River, Spain

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The spread of aquatic invasive plants is a major concern in several zones of the world's geography. These plants, which are not part of the natural ecosystem, cause a negative impact to the environment, as well as to economy and society. In Spain,

Hyperspectral Subspace Identification [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2008
Signal subspace identification is a crucial first step in many hyperspectral processing algorithms such as target detection, change detection, classification, and unmixing. The identification of this subspace enables a correct dimensionality reduction, yielding gains in algorithm performance and complexity and in data storage.

Robust linear unmixing with enhanced constraint of classification for hyperspectral remote sensing imagery

open access: yesIET Image Processing, 2022
Although hyperspectral data, especially spaceborne images, are rich in spectral information, their spatial resolution is usually low due to the limitation of sensor design and other factors.
