Modeling radiometric uncertainty for vision with tone-mapped color images
- Pattern Analysis and Machine Intelligence, IEEE Transactions on
"... Abstract-To produce images that are suitable for display, tone-mapping is widely used in digital cameras to map linear color measurements into narrow gamuts with limited dynamic range. This introduces non-linear distortion that must be undone, through a radiometric calibration process, before compu ..."

Radiometric Survey as a Useful Tool in Geological Mapping of Western Nigeria
- Journal of Geography and Geology
, 2012
"... Gamma ray Spectrometer (DISA-300) and broadband gamma ray scintillometer (BGS-ISL) were used to evaluate the radiometric properties of rocks (Igneous, Sedimentary and Metamorphic) in parts of southwestern Nigeria. The study revealed that although the two instruments used recorded different gamma rad ..."

reports/202 The Effect of Radiometric Correction on Multicamera Algorithms
"... We present preliminary results confirming the importance of radiometric correction in multicamera applications. Although, in this paper we compensate for systematic noise only, we review all noise sources in the video sensor (systematic and random). We use a simple model for radiometric correction o ..."

of digital images. The correction procedure is tested on the disparity map computation in stereo matching, particularly in a case where stereo usually fails- almost textureless white surface. Without correcting radiometricly, the matching algorithm matches systematic noise components in the two images
Robust Radiometric Calibration for Dynamic Scenes in the Wild
"... The camera response function (CRF) that maps linear irradiance to pixel intensities must be known for computa-tional imaging applications that match features in images with different exposures. This function is scene dependent and is difficult to estimate in scenes with significant mo-tion. In this ..."

-tion. In this paper, we present a novel algorithm for ra-diometric calibration from multiple exposure images of a dynamic scene. Our approach is based on two key ideas from the literature: (1) intensity mapping functions which map pixel values in one image to the other without the need for pixel correspondences
Nüesch D, Radiometric Normalization for Multimode Image Comparison
- Proc. EUSAR
, 1998
"... Intercomparison of backscatter collected by SAR sensors at heterogeneous radar look angles gives rise to highly variable ground areas being associated with each pixel location within a radar geometry (slant or ground range) image. Many elements within a digital elevation model (in map geometry) can ..."

RADIOMETRIC CALIBRATION OF DIGITAL PHOTOGRAMMETRIC CAMERA IMAGE DATA
"... Since a few years, digital frame cameras are being used for the recurrent conventional photogrammetric mapping tasks within Flanders (Belgium). As a result, area-wide, but mixed-sensor-type (Ultracam, DMC, …) time series of digital airborne imagery are emerging. Since only recently, a trend can be o ..."

DWI Denoising Using Spatial, Angular, and Radiometric Filtering
"... Abstract. In this paper, we study the effectiveness of the concurrent utilization of spatial, angular, and radiometric (SAR) information for denoising diffusion-weighted data. SAR filtering smooths diffusion-weighted images while at the same time preserves edges by means of nonlinear combination of ..."

Post-processing Approach for Radiometric Self-Calibration of Video
"... We present a novel data-driven technique for radiometric self-calibration of video from an unknown camera. Our approach self-calibrates radiometric variations in video, and is applied as a post-process; there is no need to access the camera, and in particular it is applicable to internet videos. Thi ..."
