Robust Radiometric Calibration and Vignetting Correction
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008In many computer vision systems, it is assumed that the image brightness of a point directly reflects the scene radiance of the point. However, the assumption does not hold in most cases due to nonlinear camera response function, exposure changes, and vignetting.

Radiometric Calibration from Noise Distributions
2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007A method is proposed for estimating radiometric response functions from noise observations. From the statistical properties of noise sources, the noise distribution for each scene radiance value is shown to be symmetric for a radiometrically calibrated camera.

Absolute radiometric calibration facility [PDF]
, 1995 For earth observation instruments accurate on ground calibration is necessary to characterize sensor parameters that are used for the in orbit calibration. TNO Institute of Applied Physics has developed an absolute radiometric calibration facility for the calibration of both complete instruments and diffusers.

Camera response estimation. Radiometric calibration
2009 IEEE 5th International Conference on Intelligent Computer Communication and Processing, 2009Real time vision requires accurate information about the environment that is to be processed. The quality of the acquired images depends on many factors, such as weather and lighting conditions (sun, rain, snow, fog, mist), entering and going out of tunnels, shadows, cars headlights.

The MISR radiometric calibration process
Remote Sensing of Environment, 2007One important objective of the Multi-angle Imaging SpectroRadiometer (MISR) is retrieving global aerosol loading and microphysical properties. Accuracy depends on many factors, including the availability of a complete catalog of particle types with their associated size distributions, shapes, single-scattering albedos, vertical profiles, and spectral ...

Radiometric Measurement and Calibration
20097.1 Introduction This chapter deals with the numerous measurements for which we use radiometers and spectroradiometers. This is the true meaning of the word radiometry, the measurement of radiant energy. First, we describe the types of measurements made. Next is a discussion on errors, their sources, and treatment. The generalized measurement equation

Radiometric Calibration in Thermal Infrared
2013Calibration is defined by the Working Group on Calibration and Validation (WGCV) of the International Committee on Earth Observation Satellites (CEOS) as the process of quantitatively defining the system response to known, controlled signal inputs (Belward 1999).

Construction of Radiometric Calibration Pads
8th SAGA Biennial Technical Meeting and Exhibition, 2003Radiometric data give information about the amounts of potassium, uranium and thorium that are present on the surface of the earth (Heiland 1963). This information is measured as a spectrum of the gamma radiation that is emitted as a result of decay in radioactive elements.
