Superimposing dynamic range [PDF]

open access: yesACM SIGGRAPH Asia 2008 papers, 2008
We present a simple and cost-efficient way of extending contrast, perceived tonal resolution, and color space of reflective media, such as paper prints, hardcopy photographs, or electronic paper displays. A calibrated projector-camera system is applied for automatic registration, radiometric scanning and superimposition.

Highlights Analysis System (HAnS) for Low Dynamic Range to High Dynamic Range Conversion of Cinematic Low Dynamic Range Content

open access: yesIEEE Access, 2021
We propose a novel and efficient algorithm for detection of specular reflections and light sources (highlights) in cinematic content. The detection of highlights is important for reconstructing them properly in the conversion of the low dynamic range ...

Robust Dynamic Range Computation for High Dynamic Range Content [PDF]

open access: yesElectronic Imaging, 2017
High dynamic range (HDR) imaging has become an important topic in both academic and industrial domains. Nevertheless, the concept of dynamic range (DR), which underpins HDR, and the way it is measured are still not clearly understood. The current approach to measure DR results in a poor correlation with perceptual scores (r ≈ 0.6).

Dynamic Range Expansion Using Cumulative Histogram Learning for High Dynamic Range Image Generation

open access: yesIEEE Access, 2020
In modern digital photographs, most images have low dynamic range (LDR) formats, which means that the range of light intensities from the darkest to the brightest is much lower than the range that can be perceived by the human eye.

Increasing ADC dynamic range in information-measuring systems by methods of digital signal processing [PDF]

open access: yesОмский научный вестник, 2020
The article deals with the method of increasing the dynamic range of a standard analog-to-digital converter. The method is based on interpolation of signal sections, which are limited in amplitude, using undistorted sections.
