Highlights Analysis System (HAnS) for Low Dynamic Range to High Dynamic Range Conversion of Cinematic Low Dynamic Range Content [PDF]
IEEE 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 ...

Superimposing dynamic range [PDF]
ACM 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.

Different Heterotrimeric G Protein Dynamics for Wide-Range Chemotaxis in Eukaryotic Cells
Frontiers in Cell and Developmental Biology, 2021 Chemotaxis describes directional motility along ambient chemical gradients and has important roles in human physiology and pathology. Typical chemotactic cells, such as neutrophils and Dictyostelium cells, can detect spatial differences in chemical ...

Robust Dynamic Range Computation for High Dynamic Range Content [PDF]
Electronic 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).

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

DFT Spread-Optical Pulse Amplitude Modulation for Visible Light Communication Systems
IEEE Access, 2022 DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) has been proposed in visible light communication (VLC) to overcome the limited modulation bandwidth of light emitting diode (LED).

Dynamic-range estimation [PDF]
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2006 It has been widely recognized that the dynamic-range information of an application can be exploited to reduce the datapath bitwidth of either processors or application-specific integrated circuits and, therefore, the overall circuit area, delay, and power consumption.

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

A Scheme for Long-distance High-resolution Detection of Fiber Link
Guangtongxin yanjiu, 2021 Aiming at the problem of low spatial resolution of Optical Time Domain Reflectometer (OTDR) in long distance optical fiber link detection, this paper proposes a new scheme of Linear Frequency Modulation (LFM) -Golay OTDR.
