Mixing tone mapping operators on the GPU by differential zone mapping based on psychophysical experiments [PDF]
, 2016 © 2016 In this paper, we present a new technique for displaying High Dynamic Range (HDR) images on Low Dynamic Range (LDR) displays in an efficient way on the GPU. The described process has three stages. First, the input image is segmented into luminance

Human Visual System Model-Based Optimized Tone Mapping of High Dynamic Range Images
IEEE Access, 2021 High dynamic range (HDR) image and video technology can provide significant picture quality improvement over the standard dynamic range (SDR). However, when HDR content is represented on an SDR display, dynamic range compression may result in image ...

Visible and Near-Infrared Image Acquisition and Fusion for Night Surveillance
Chemosensors, 2021 Image fusion combines images with different information to create a single, information-rich image. The process may either involve synthesizing images using multiple exposures of the same scene, such as exposure fusion, or synthesizing images of ...

Fully-automatic inverse tone mapping algorithm based on dynamic mid-level tone mapping [PDF]
, 2020 High Dynamic Range (HDR) displays can show images with higher color contrast levels and peak luminosities than the common Low Dynamic Range (LDR) displays. However, most existing video content is recorded and/or graded in LDR format.

Deep Reformulated Laplacian Tone Mapping
CoRR, 2021 Wide dynamic range (WDR) images contain more scene details and contrast when compared to common images. However, it requires tone mapping to process the pixel values in order to display properly. The details of WDR images can diminish during the tone mapping process.

The Modulation Technology of Chaotic Multi-Tone and its Application in Covert Communication System
IEEE Access, 2019 With the development of communication countermeasure technology, the existing communication mode is exposed to intercept or decipher in the covert transmission of information. Therefore, the development of a new concept and principle covert communication

Invertible Tone Mapping with Selectable Styles
CoRR, 2021 Although digital cameras can acquire high-dynamic range (HDR) images, the captured HDR information are mostly quantized to low-dynamic range (LDR) images for display compatibility and compact storage. In this paper, we propose an invertible tone mapping method that converts the multi-exposure HDR to a true LDR (8-bit per color channel) and reserves the

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
