2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
The Hyperspectral Imager Suite (HISUI) is the Japanese next-generation Earth observation project, which will be composed of hyperspectral imager (185 spectral bands in VNIR-SWIR region with 30 m spatial resolution) and multispectral imager (4 spectral bands in VNIR region with 5 [m] spatial resolution), and is being developed by Japanese Ministry of ...

Assessment of HISUI radiometric performance using vicarious calibration and cross-calibration
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The Hyperspectral Imager Suite (HISUI) is a future hyper-spectral and multispectral sensor developed by Japanese Ministry of Economy, Trade, and Industry (METI). Radiometric calibration of satellite sensor system is very important for the higher level products with high quality.

OCO/GOSAT Preflight Cross-Calibration Experiment
IEEE Transactions on Geoscience and Remote Sensing, 2010The Orbiting Carbon Observatory (OCO) by NASA's Jet Propulsion Laboratory (JPL) and Greenhouse gases Observing SATellite (GOSAT) by JAXA were built to provide independent measures of the global distributions of carbon dioxide (CO2) from space. GOSAT achieved a successful orbit on January 23, 2009, and OCO failed its launch attempt on February 24, 2009.

Camera calibration by vanishing point and cross ratio
International Conference on Acoustics, Speech, and Signal Processing, 2003The authors present a unified camera calibration method in which radial distortions can be considered or ignored. The usually tangled process of calibrating intrinsic and extrinsic camera parameters in the zero-distortion case is separated by using vanishing points as calibration points.

Calibration and cross-validation of MCCB and CogState in schizophrenia
Psychopharmacology, 2015Cognitive impairment associated with schizophrenia is a key predictor of functional outcomes. The FDA-accepted MATRICS Consensus Cognitive Battery (MCCB) is held to be the gold standard measure but there are concerns about its ease of administration, reliance on language causing problems with translation and possible practice effects.

Calibration of estuarine current crosses
Estuarine, Coastal and Shelf Science, 1982Abstract Tethered current crosses are simple, reliable tools in making measurements of estuarine currents in the absence of surface waves. The standard error of the estimate of current speed is less than 5 cm s−1 for the particular crosses and weights used in a calibration experiment.

Radiometric cross-calibration of Terra ASTER and MODIS
SPIE Proceedings, 2015Calibration and validation play an essential role during the acquisition and processing of satellite data for Earth Observing System satellites in addition to being an integral part of maintaining scientific values of archived satellite data. The Advanced Spaceborne Thermal Emission and Reflection and Radiometer (ASTER) and Moderate Resolution Imaging ...

Multicenter comparison of calibration and cross calibration of PET scanners.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 2002The purpose of this study was to compare the calibration of PET scanners and their cross calibration to peripheral devices in a multicenter study.Twenty-three dedicated PET scanners were investigated, applying standardized protocols. To ensure exact determination of the activity used, dose calibrators were checked using (68)Ge standards.Nine of 19 and ...

Cross-Calibration Between QuikSCAT and Oceansat-2
IEEE Transactions on Geoscience and Remote Sensing, 2014This paper presents the procedure to perform cross-calibration of radar backscatter between the QuikSCAT and Oceansat-2 ocean wind scatterometers. Both QuikSCAT and Oceansat-2 are Ku-band dual pencil beam, rotating antenna scatterometers with similar design.

A reflectance-based cross calibration of the Landsat sensors
Earth Observing Systems XXII, 2017First launched in 1972, the Landsat satellite sensors have provided the longest continuous record of high quality images of the Earth’s surface that are used in both civilian and military applications. Extraction of quantitative information (e.g., surface reflectance) from the Landsat image data is only possible through an accurate absolute radiometric
