Forward Looking Radar Imaging by Truncated Singular Value Decomposition and Its Application for Adverse Weather Aircraft Landing [PDF]

open access: yesSensors, 2015
The forward looking radar imaging task is a practical and challenging problem for adverse weather aircraft landing industry. Deconvolution method can realize the forward looking imaging but it often leads to the noise amplification in the radar image. In

Truncated singular value decomposition in ripped photo recovery [PDF]

open access: yesITM Web of Conferences, 2021
Singular value decomposition (SVD) is one of the most useful matrix decompositions in linear algebra. Here, a novel application of SVD in recovering ripped photos was exploited. Recovery was done by applying truncated SVD iteratively.

Hyperspectral Multispectral Image Fusion via Fast Matrix Truncated Singular Value Decomposition

open access: yesRemote Sensing, 2022
Recently, methods for obtaining a high spatial resolution hyperspectral image (HR-HSI) by fusing a low spatial resolution hyperspectral image (LR-HSI) and high spatial resolution multispectral image (HR-MSI) have become increasingly popular.

A New Truncation Strategy for the Higher-Order Singular Value Decomposition [PDF]

open access: yesSIAM Journal on Scientific Computing, 2012
We present an alternative strategy for truncating the higher-order singular value decomposition (T-HOSVD). An error expression for an approximate Tucker decomposition with orthogonal factor matrices is presented, leading us to propose a novel truncation strategy for the HOSVD, which we refer to as the sequentially truncated higher-order singular value ...

An Investigation of Extended-Dimension Embedded CKF-SLAM Based on the Akaike Information Criterion [PDF]

open access: yesSensors
Simultaneous localization and mapping (SLAM) faces significant challenges due to high computational costs, low accuracy, and instability, which are particularly problematic because SLAM systems often operate in real-time environments where timely and ...

Reconstruction of Mercury's internal magnetic field beyond the octupole [PDF]

open access: yesAnnales Geophysicae, 2022
The reconstruction of Mercury's internal magnetic field enables us to take a look into the inner heart of Mercury. In view of the BepiColombo mission, Mercury's magnetosphere is simulated using a hybrid plasma code, and the multipoles of the internal ...
