Attention Mechanism Cloud Detection With Modified FCN for Infrared Remote Sensing Images

IEEE Access, 2021
Semantic segmentation (SS) has been widely applied for cloud detection (CD) in remote sensing images (RSIs) with high spatial and spectral resolution because of its effective pixel-level feature extraction structure.

DenseFuse: A Fusion Approach to Infrared and Visible Images [PDF]

IEEE Transactions on Image Processing, 2018
In this paper, we present a novel deep learning architecture for infrared and visible images fusion problems. In contrast to conventional convolutional networks, our encoding network is combined with convolutional layers, a fusion layer, and dense block ...

Bandgap-independent photoconductive detection in two-dimensional Sb2Te3

Communications Materials, 2022
Achieving photodetectors with a wide spectral range and rapid response remains challenging. Here, Sb2Te3 nanosheets are used to construct a photodetector that covers visible to millimeter wavelengths, with a fast response time of 900 ns.

Local Spatial–Temporal Matching Method for Space-Based Infrared Aerial Target Detection

Sensors, 2022
The feature of a space-based infrared signal is that the intensity of clutter is much stronger than that of an aerial target. Such a feature poses a great challenge to aerial target detection since the existing infrared target detection methods are prone

In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope [PDF]

SPIE Astronomical Telescopes + Instrumentation, 2004
The Infrared Array Camera (IRAC) is one of three focal plane instruments on board the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 μm in two nearly adjacent fields of view ...

Denoising and Feature Extraction for Space Infrared Dim Target Recognition Utilizing Optimal VMD and Dual-Band Thermometry

Machines, 2022
Space target feature extraction and space infrared target recognition are important components of space situational awareness (SSA). However, owing to far imaging distance between the space target and infrared detector, the infrared signal of the target ...

ISO continuum observations of quasars at z=1-4 I.Spectral energy distributions of quasars from the UV to far-infrared [PDF]

, 2000
Eight luminous quasars with $ -30 < M_B < -27$ at z = 1.4 - 3.7 have been observed in the mid- and far-infrared using ISO. All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ...
