Hyperspectral Imaging (HSI) in anatomic left liver resection

International Journal of Surgery Case Reports, 2019
Abstract Introduction Anatomic liver resection is based on the description of functional segments, which rely on the organs arterial and portal venous blood supply. Vascular inflow control of the left liver is performed by occlusion of the left hepatic artery (LHA) and left portal vein (LPV ...

Maize disease detection based on spectral recovery from RGB images

Frontiers in Plant Science, 2022
Maize is susceptible to infect pest disease, and early disease detection is key to preventing the reduction of maize yields. The raw data used for plant disease detection are commonly RGB images and hyperspectral images (HSI).

Compression and Noise Reduction of Hyperspectral Images using Tucker Decomposition and Discerete Wavelet Transform [PDF]

, 2012
International audienceThe compression of hyperspectral images (HSIs) becomes recently very attractive issue for remote sensing applications because of their volumetric data. In this paper, an efficient method for joint hyperspectral image compression and

CSA-MSO3DCNN: Multiscale Octave 3D CNN with Channel and Spatial Attention for Hyperspectral Image Classification

Remote Sensing, 2020
3D convolutional neural networks (CNNs) have been demonstrated to be a powerful tool in hyperspectral images (HSIs) classification. However, using the conventional 3D CNNs to extract the spectral−spatial feature for HSIs results in too many ...

EnMAP: hyperspectral Imager (HSI) for Earth observation: current status [PDF]

International Conference on Space Optics — ICSO 2018, 2019
The Environmental Mapping and Analysis Program (EnMAP) is a German space borne science mission that aims at characterizing the Earth’s environment on a global scale. The single payload of the satellite is the Hyperspectral Imager (HSI). It is capable of measuring the solar radiance reflected from the Earth’s surface as a continuous spectrum in the ...

HSICityV2: Urban Scene Understanding via Hyperspectral Images [PDF]

, 2021
Light in all spectrum travel in the physical world. The trichromatism (RGB) human vision captures and understands it. Machine vision makes an analogy which use RGB camera for semantic segmentation and scene understanding.

Combining spectral matching and anomalous change detection for target rediscovery in hyperspectral images [PDF]

, 2014
In surveillance applications, tracking a specific target by means of subsequent acquisitions over the monitored area is of great interest. Multitemporal HyperSpectral Images (HSIs) are particularly suitable for this application. Multiple HSIs of the same

Spectral Correlation and Spatial High–Low Frequency Information of Hyperspectral Image Super-Resolution Network

Remote Sensing, 2023
Hyperspectral images (HSIs) generally contain tens or even hundreds of spectral segments within a specific frequency range. Due to the limitations and cost of imaging sensors, HSIs often trade spatial resolution for finer band resolution.

In vivo evaluation of a hyperspectral imaging system for minimally invasive surgery (HSI-MIS)

Surgical Endoscopy, 2023
Abstract Background Hyperspectral Imaging (HSI) is a reliable and safe imaging method for taking intraoperative perfusion measurements. This is the first study translating intraoperative HSI to an in vivo laparoscopic setting using a CE-certified HSI-system for minimally invasive surgery (HSI-MIS).
