This paper presents a novel method for fusing two or more differently exposed Low Dynamic Range LDR images of a High Dynamic Range HDR scene. Illumination estimation is applied to coarse and fine scales leading to the contrast decomposition process at both scales and assessing to the definition of the “well-exposed” pixels in the original exposure sequence. Membership functions are then employe...
High Dynamic Range (HDR) Photography is used to capture 180 images of the sky dome and provide data for image-based lighting in lieu of CIE sky models.
Robotics applications often requires vision systems capable of capturing a large amount of information related to a scene. With many camera sensors, the perception of information is limited in areas with strong contrasts. The High Dynamic Range (HDR) vision system can deal with these limitations. This paper describes the HDR-ARtiSt hardware platform (High Dynamic Range Advanced Real-time imagin...
High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to correct optical defects in real time. Indeed, these defects scatter light and give birth to speckles in the image plane. Speckles can be cancelled by driving a deformable mirror to measure and compen...
The development of single-shot, high-dynamic-range temporal measurement devices has become necessary for characterizing high-energy petawatt laser pulses. Because of the low repetition rate of such systems, no device offers high-dynamic-range measurements in a single-shot mode. In addition, investigating the unexpected temporal behavior of pulses amplified by new techniques such as analyzed in ...
In this report we propose a HDR synthesis framework based on MAP estimation. We start with introducing a physical model for the HDR imaging process, and then make several basic assumptions. Based on these we reach a model where our previous formulation on HDR deghosting could be considered an instantiation, by picking particular densities and choosing appropriate parameters. Finally, we extend ...
The authors test 168 luminance-calibrated high dynamic range photographs with associated subjective user data against a set of plausible visual comfort metrics and identify metric thresholds at which discomfort can be consistently identified with minimal false-positives. Correlations were identified with vertical eye illuminance, DGI, DGP 5 ∗ Ltask, max. window luminance and max. workplane lumi...

This contribution evaluates the impact of chroma subsampling using two different downsampling filters using objective metric. Objective results show that distributing 4:4:4 is more efficient than its 4:2:0 counterpart for medium to high bit-rates. For low bit-rates, this increase in efficiency is reduced and in some cases even reversed.
