Stereo Matching in the Presence of Sub-Pixel Calibration Errors

open access: yes, 2009
Stereo matching commonly requires rectified images that are computed from calibrated cameras. Since all under-lying parametric camera models are only approximations, calibration and rectification will never be perfect.

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Introducing Equivalent Radar Cross Section – A First Step Toward new Radiometric Requirement Definitions

open access: yes, 2014
Stringent radiometric SAR system requirements often significantly shape the design and cost of modern SAR systems. Yet the wording in current requirement documents is ambiguous, and a diligent conformance assessment at the end of project phases currently

Evaluating tools for predicting and measuring radiometric performance of germicidal ultraviolet systems

open access: yesPhotochemistry and Photobiology, EarlyView.
An evaluation of simulation and measurement tools for germicidal ultraviolet (GUV) systems is presented to inform their design and deployment to control the spread of airborne pathogens. Abstract Germicidal ultraviolet (GUV) air treatment technologies can be effective and safe for reducing airborne disease transmission.

Radiometric calibration methods from image sequences

open access: yes, 2008
In many computer vision systems, an image of a scene is assumed to directly reflect the scene radiance. However, this is not the case for most cameras as the radiometric response function which is a mapping from the scene radiance to the image brightness

Railroad Valley Radiometric Calibration Test Site (RadCaTS) as Part of a Global Radiometric Calibration Network (RadCalNet)

open access: yes, 2020
The Radiometric Calibration Network (RadCalNet) is a coordinated multinational effort to provide in situ data that are suitable for the radiometric calibration and validation of Earth observation sensors that operate in the visible to shortwave infrared ...

Geometric, Radiometric, Polarimetric and Along-Track Interferometric Calibration of the new F-SAR System of DLR in X-Band

open access: yes, 2008
Since November 2006, DLR operates F-SAR - a new airborne SAR sensor beside its experimental airborne SAR sensor E-SAR. F-SAR is a totally new development utilizing most modern hardware.
