Gradients in urban material composition: A new concept to map cities with spaceborne imaging spectroscopy data [PDF]

open access: yes, 2019
To understand processes in urban environments, such as urban energy fluxes or surface temperature patterns, it is important to map urban surface materials. Airborne imaging spectroscopy data have been successfully used to identify urban surface materials

Texture analysis of vertebral bone marrow using chemical shift encoding–based water-fat MRI:a feasibility study [PDF]

open access: yes, 2019
Summary This feasibility study investigated the spatial heterogeneity of the lumbar vertebral bone marrow using chemical shift encoding–based water-fat MRI. Acquired texture features like contrast and dissimilarity allowed for differentiation of pre- and

Three‐dimensional point cloud reconstruction of inverse synthetic aperture radar image sequences based on back projection and iterative closest point fusion

open access: yesIET Radar, Sonar & Navigation, 2023
In order to recover the three‐dimensional (3D) structure of the target from sequential inverse synthetic aperture radar (ISAR) images, the factorisation method is generally used.
