Recalibration of over 35 Years of Infrared and Water Vapor Channel Radiances of the JMA Geostationary Satellites

open access: yesRemote Sensing, 2019
Infrared sounding measurements of the Infrared Atmospheric Sounding Interferometer (IASI), Atmospheric Infrared Sounder (AIRS), and High-resolution Infrared Radiation Sounder/2 (HIRS/2) instruments are used to recalibrate infrared (IR; ~11 µm ...

Identifying Radiation Absorption and Creating Shadow on the Body of Pigeon Towers in the Villages of Isfahan and Tabriz [PDF]

open access: yesمسکن و محیط روستا, 2021
In most parts of our country, especially the two hot and dry and cold and dry climates, there have been pigeon towers with different shapes and forms for keeping and breeding pigeons. Circular or square in plan, they are made of clay and brick.

A Study on the Blue Coloration of Ao-ike Pond, Aomori Prefecture, Japan: Formulation of a Physical Model in Terms of Radiance and Image Analyses

open access: yesApplied Sciences, 2021
The blue coloration model of a closed pond, Ao-ike Pond, Aomori Prefecture, Japan, was formulated in terms of radiance by applying a theory of observation devices proposed by Szirmay-Kalos (2008) and Hanaishi’s reverse ray tracing method.

Machine learning estimation of tissue optical properties

open access: yesScientific Reports, 2021
Dynamic, in vivo measurement of the optical properties of biological tissues is still an elusive and critically important problem. Here we develop a technique for inverting a Monte Carlo simulation to extract tissue optical properties from the ...

Urban Radiance Fields

open access: yes2022 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2022
The goal of this work is to perform 3D reconstruction and novel view synthesis from data captured by scanning platforms commonly deployed for world mapping in urban outdoor environments (e.g., Street View). Given a sequence of posed RGB images and lidar sweeps acquired by cameras and scanners moving through an outdoor scene, we produce a model from ...

Using Ground Targets to Validate S-NPP VIIRS Day-Night Band Calibration

open access: yesRemote Sensing, 2016
In this study, the observations from S-NPP VIIRS Day-Night band (DNB) and Moderate resolution bands (M bands) of Libya 4 and Dome C over the first four years of the mission are used to assess the DNB low gain calibration stability.
